A novel wastewater treatment solution currently undergoing evaluation at the Wahiawā Wastewater Treatment Plant on Oʻahu could offer a crucial, cost-effective path forward as Hawaiʻi faces a massive statewide infrastructure overhaul.

The Hawaiʻi Onsite Wastewater Technology Evaluation Program (HOWTEP) was officially launched during the Wastewater Innovation Tech Showcase on August 26, at the Wahiawā Wastewater Treatment Plant.

Executed by the University of Hawaiʻi at Mānoa (WRRC), HOWTEP is a three-year pilot testing program funded by companion bills and . WRRC evaluates innovative systems and provides evaluation reports to the Hawaiʻi Department of Health to support their decision-making and certification process. This directly accelerates the commercialization and approval of affordable wastewater technologies.

The initiative advances accessible, decentralized wastewater solutions to help property owners meet the mandate requiring the replacement, conversion or closure of nearly 88,000 cesspools across the state by January 1, 2050. Beyond system certification, HOWTEP serves as a multi-purpose hub for WRRC to conduct research, offer hands-on student training and perform community outreach.

Honu Hub

Honu Hub, which is supported by a $5 million National Science Foundation grant, is the first technology to be evaluated under the HOWTEP platform. It is led by Assistant Professor Zhiyue Wang (WRRC and Department of Civil, Environmental and Construction Engineering), Professor and Director Tao Yan (WRRC and Department of Civil, Environmental and Construction Engineering) and Professor Daniel Yeh (University of South Florida).

Honu Hub is a decentralized wastewater treatment system designed to process sewage completely above ground. By packing its technology into a compact 52-square-foot space—roughly the size of a standard garden shed—the unit eliminates the need for expensive heavy machinery, extensive excavation and costly landscape restoration.

For many homeowners, replacing a cesspool with a conventional septic system costs between $30,000 and $50,000—a financial burden amplified by difficult terrain, high water tables and tight lot boundaries. Honu Hub was engineered as an affordable alternative designed to drastically lower these conversion costs.

“The WRRC team鈥檚 role in this is to help with research and development to improve the technology and study the fate and transport of emerging contaminants in this system,” Wang said.

The University of Hawaiʻi at Mānoa has received a $2 million award from the National Science Foundation (NSF) to lead a multi-institutional effort to develop artificial intelligence (AI)-enabled tools that can help detect environmental threats to food production systems before they become major problems. The effort comes as public health officials continue to investigate foodborne illness outbreaks tied to cyclospora, underscoring the need for faster, more proactive approaches to identifying potential threats in the food supply.

The $4 million NSF Established Program to Stimulate Competitive Research (EPSCoR) Track II Focused EPSCoR Collaboration (FEC) award is led by 糖心视频 Mānoa in partnership with the University of Nebraska鈥揕incoln. 糖心视频鈥檚 portion of the award is $2 million, with the four-year project starting September 1, 2026. This marks only the second time 糖心视频 has received an NSF EPSCoR Track II FEC award.

Team of experts to cross variety of fields

The project will combine AI, environmental sampling, advanced genetic analysis and high-resolution chemical analysis to identify and monitor potential risks to aquaculture, livestock and agricultural systems.

Led by principal investigator Tao Yan, director of the (WRRC) and professor in the , the project brings together researchers from across 糖心视频, including WRRC, College of Engineering, 糖心视频 Cancer Center, School of Ocean and Earth Science and Technology and College of Tropical Agriculture and Human Resilience.

“Food production systems are increasingly challenged by microbial pathogens and chemical contaminants that can threaten animal health, food safety and economic sustainability,” Yan said. “By combining environmental surveillance with AI, we aim to develop early-warning technologies that can identify emerging risks before they reach critical levels. This collaboration will strengthen Hawaiʻi鈥檚 and Nebraska鈥檚 research capacity while preparing the next generation of scientists and engineers to address complex challenges in food security.”

Creating a proactive approach

Current monitoring methods often identify problems only after disease outbreaks occur or contaminants have reached harmful levels. The project aims to create a proactive approach by continuously analyzing environmental data to detect warning signs earlier.

Researchers will develop new AI models capable of interpreting complex biological and chemical data, including information from metagenomics (the study of genetic material collected from environmental samples) and high-resolution mass spectrometry, which identifies chemical compounds.

The research team will test the technologies in aquaculture and beef cattle production systems, with the goal of improving food safety, protecting animal health and increasing the resilience of food production systems.

The collaboration will support STEM education and workforce development by providing research opportunities for junior faculty members, graduate and undergraduate students, and K–12 participants. Outreach efforts will engage industry partners, regulators and communities to encourage adoption of new technologies.

The partnership builds research capacity in two EPSCoR jurisdictions (Hawaiʻi and Nebraska) while establishing a long-term collaboration focused on using AI and biotechnology to address food system challenges.

The , facilitated by the University of Hawaiʻi, hosted its fifth Scientific Oversight Workshop last week on 糖心视频 惭腻苍辞补鈥檚 campus, bringing together a mix of 糖心视频 teams, the Agency for Toxic Substances and Disease Registry and national environmental health experts.

Led by the Thompson School Registry Hub, one of the collaborating units at the Red Hill Registry, the event worked to understand existing environmental data and the registry鈥檚 early exposure data to assess which information would be useful for determining exposure in future health research of registry participants.

“As a result of this workshop and our cross-sector expert dialogue, we are able to begin to frame our approach to assessing an individual鈥檚 exposure to jet-fuel-contaminated water,” said Rosana “Sanie” Weldon, director of the Red Hill Registry.

Water experts, hydrologists, microbiologists and chemists from the (WRRC) and shared project-related updates on jet fuel degradation by fuel-eating microbes, hydraulic modeling of the Red Hill water lines, chemical compound classifications, early water screening results and more.

The Red Hill Registry shared current research methodologies, early exposure data reported by registry participants and community outreach efforts aimed at increasing the scientific rigor of the data being collected by the registry.

“The types of studies and health analyses that we want to be able to investigate will only be really effective if there’s a large cohort of folks enrolled and participating with the registry,” said Eamonn Clarke, postdoctoral researcher in the Marron Lab within WRRC and presenter at the Scientific Oversight Workshop.

The group discussed the challenges of complex data sets as well as how to conduct future research with assumptions and generalizations for unknown data.

“We have made a lot of progress at the workshop toward understanding what was in the water, when, and which areas were hardest hit. All of those things matter as we try to understand the health issues that emerged,” said Gina Solomon, Chief of the Division of Occupational, Environmental, and Climate Medicine at University of California, San Francisco.

The next Red Hill Registry Scientific Oversight Workshop is proposed for spring 2027.

Co-designed with the community, the Red Hill Registry aims to track health outcomes to inform future research and clinical guidance on fuel exposure and provide resources for the estimated 93,000 people who experienced the fuel spill.

A new project led by the University of Hawaiʻi at 惭腻苍辞补 will use artificial intelligence (AI) to help predict how rising seas and stronger storms could threaten coastal freshwater supplies and ecosystems.

Associate Professor Jonghyun “Harry” Lee of the 糖心视频 惭腻苍辞补 and has been awarded a under its Collaborations in Artificial Intelligence and Geosciences program. 糖心视频 惭腻苍辞补 will serve as the lead institution on a three-year, nearly $1 million collaborative project, alongside the University of Texas at Austin, to advance AI applications in geoscience.

Rising seas, stronger storms, saltwater contamination of freshwater resources and coastal ecosystem degradation pose increasing threats to coastal communities. These environmental pressures impact drinking water supplies, agriculture, infrastructure, local economies and daily life for millions of people.

To address these challenges, the joint project will develop fast, accessible AI models to better understand how water exchanges between coastal aquifers and the ocean. By combining recent advances in AI with traditional environmental modeling, the team aims to predict critical coastal risks鈥攕uch as seawater intrusion into freshwater aquifers and freshwater flowing from land into the ocean鈥攆aster and more accurately.

“This project will improve our understanding and prediction of how groundwater and the ocean interact in Hawaiʻi鈥檚 coastal aquifers, helping communities better protect freshwater resources and coastal ecosystems from challenges, such as seawater intrusion and coastal inundation,” principal investigator Lee said.

Advancing coastal science through next-gen AI

The researchers will develop a new system that combines AI with proven physics models to better understand coastal water systems. This approach creates high-speed 鈥渟urrogate models鈥� capable of running complex simulations of groundwater and ocean interactions at a fraction of the cost, while preserving essential physics laws at the land-sea boundary.

Key features and goals of the project include:

• Flexible AI architecture: Combining different AI tools to analyze both long-term ocean patterns and short-term events, such as storm surges.
• Real-world testing: Validating models on benchmark applications in Hawaiʻi and Texas coastal systems.
• Near-real-time forecasts: Enabling rapid assessments of seawater intrusion and coastal groundwater discharge to support digital twin models of complex ecosystems.
• Practical decision tools: Providing actionable insights to guide water management, infrastructure planning and long-term coastal resilience.
• Open science and education: Developing open-source software, interactive visualization tools, and interdisciplinary training for students and early-career researchers.

“Students and postdocs working on this project will be supported by hands-on research and training at the intersection of groundwater hydrology, coastal science, computational modeling, and artificial intelligence, preparing them for careers addressing Hawaiʻi鈥檚 water and environmental challenges,” Lee stated.

While long-term data shows that Hawaiʻi is getting drier overall, short, intense downpours that cause sudden, dangerous flash floods are getting stronger in the islands, according to a new study by researchers at the University of Hawaiʻi at Mānoa.

Published in the , the research from the College of Tropical Agriculture and Human Resilience (CTAHR) is the first comprehensive study to analyze extreme hourly rainfall patterns across the state over 50 years (1966鈥�2020). The team examined decades of hourly data from 117 rain gauges across Kauaʻi, Oʻahu, Molokaʻi, Maui and Hawaiʻi Island, uncovering climate trends that traditional 24-hour daily averages often miss.

Bursts of intense rain

In steep, mountain-filled tropical watersheds like 贬补飞补颈ʻ颈鈥檚, bursts of intense rain lasting one to six hours can overwhelm stream channels and storm drains before emergency alerts are even issued.

“If we want to understand extreme weather, like storms and floods, we really need to look at short-duration, high-temporal-resolution data rather than daily or monthly averages,” said Professor Yinphan Tsang of CTAHR鈥檚 Department of Natural Resources and Environmental Management and the principal investigator.

The study鈥檚 major findings include:

• Common heavy rains, happening once every two years, are generally becoming less intense across the state.
• Short, sudden bursts of rain lasting one to three hours—the severe storms that usually occur only once every 20 to 100 years—are getting significantly stronger.
• Storms lasting 6 hours or longer are weakening more noticeably than shorter one- to three-hour storms.

Researchers noted that rainfall trends vary widely even between neighboring areas. Because of 贬补飞补颈ʻ颈鈥檚 unique mountains and island terrain, rainfall intensity can increase in one neighborhood while decreasing just a few miles away.

Researchers also identified two distinct peaks when Hawaiʻi is most vulnerable to extreme hourly rain events: October through December and February through March. These heavy rains are overall driven by cold fronts, Kona storms and other winter weather systems moving through the islands. The extreme events occurring from February through March, near the end of the wet season, were unexpected and could take people by surprise. Other systems, such as tropical storms, could also bring extreme rainfall during the summer season.

Vital data for climate adaptation

The findings offer updates for emergency responders, county planners and infrastructure design.

The study was a collaborative effort at 糖心视频 Mānoa bringing together experts from CTAHR, the School of Ocean and Earth Science and Technology, the College of Social Sciences and the Water Resources Research Center. The research was primarily compiled by Maxime Gayte with co-authors including faculty members Professor Yinphan Tsang, Professor Pao-Shin Chu (Hawaiʻi State Climatologist), Professor Thomas W. Giambelluca, Jr., Researcher Yu-Fen Huang, and Researcher Hanpei Zhang.

A new University of Hawaiʻi report released August 17 finds that the 糖心视频 System has significant strengths in water-related education, research and workforce development, but greater coordination across programs could help Hawaiʻi build stronger pathways into careers focused on wai (water) stewardship.

The report co-authored by a multidisciplinary team of 糖心视频 researchers is based on interviews with 38 糖心视频 faculty members, alumni, program directors and coordinators. It identifies opportunities to better connect students with water-related courses, hands-on learning, mentors and employment opportunities across the state.

Key insights from interviews:

• Interviewee career pathways were often shaped by connections to family and place (especially for ʻōiwi and kamaʻāina interviewees), mentors (inside and outside of academia) and funding availability.
• There are many water-related courses already offered by 糖心视频 Mānoa and many faculty with water relevant expertise. These tend to be scattered across different departments because of the broad multi-disciplinary nature of water stewardship.
• Overall, interviewees felt that despite strong wai course offerings across the 糖心视频 Mānoa campus, there was a lack of coordination or visibility of water courses and a need for clearer connections between curriculum and employment opportunities.
• Despite the absence of a singular wai degree pathway, several existing programs offer freshwater credentialing options. Faculty and program coordinators help students navigate their academic journeys and find relevant wai courses and mentors using informal referral networks built on pre-existing relationships.
• Interviewees discussed a variety of ideas for credit and non-credit wai education options including certificates, a water focused master鈥檚 degree, non-credit training and a Wai 100 course.
• The 糖心视频 System has strong research infrastructure and existing mechanisms for student research. However, faculty and alumni expressed support for more experiential learning opportunities and curriculum incorporating place- and culture-based learning.
• Faculty and staff understanding of and connection to water sector employers plays a key role in student access to career pathways.
• Personnel from long-standing education and career pathway programs emphasized a few key aspects of their programming approaches, including that 1) programs are adaptive, allowing space and time for growth of the program, 2) programs emphasize nurturing the “gifts” of participants rather than attempting to identify and fill gaps in skills or knowledge and 3) relationships are central and developing trust across staff and program participants is important.
• These programs consider the long-term trajectory of their participants as their primary indicator of success. They want to see program participants secure employment or pursue a degree in a particular field.
• Silos in curricula and conceptualizations of wai may be limiting Hawaiʻi鈥檚 progress in developing effective water management. Leadership to support coordination and systems alignments is needed.

This research is a multi-department collaboration including the 糖心视频 Mānoa , , , and . Funding for this work comes from the Hawaiian Islands Environmental Finance Center of the Hawaiʻi Community Foundation.

A University of Hawaiʻi at Mānoa faculty member has received a $660,000 National Science Foundation (NSF) Faculty Early Career Development (CAREER) Award to study how fuel contamination can affect drinking water during the treatment process.

Emily Marron, an assistant specialist in the and cooperating graduate faculty and instructor in the , will lead the five-year project, which runs through June 2031.

The research focuses on what happens when chlorine—commonly used to disinfect drinking water—reacts with fuel that has entered water supplies after spills or leaks. While chlorine is regularly added to drinking water systems to help control bacterial growth and eliminate harmful pathogens, it can also react with fuel-related chemicals to create unintended byproducts that may pose health risks.

Marron and her research team will use advanced analytical chemistry techniques, such as high-resolution mass spectrometry, to identify the compounds formed during these reactions, measure how quickly they develop and better understand how fuel changes over time affect water treatment. The findings could improve how contaminated drinking water systems are evaluated and treated following fuel releases.

Clean drinking water, complex contamination

“Clean drinking water is something every community depends on,” Marron said. “I hope this research gives scientists and water professionals better tools to understand complex contamination events and make informed decisions that help protect public health.”

The project could also provide new insight into the types of chemical compounds people might have been exposed to in drinking water following the Red Hill fuel contamination in 2021. Rather than recreating the specific conditions of the Red Hill incident, the research will use controlled laboratory experiments to build a scientific framework for studying fuel-contaminated water. The research could also help inform public health decisions and improve response strategies during contamination events.

In addition to the research, the project includes education and community outreach. Marron will develop an undergraduate teaching module in partnership with local water professionals, including the Honolulu Board of Water Supply, to give students hands-on learning opportunities in environmental chemistry and drinking water treatment.

The project will also establish a community-centered laboratory that expands access to low-cost drinking water testing. The effort is designed to help residents better understand water quality, environmental chemistry and the science behind keeping drinking water safe.

The NSF CAREER program is among the foundation鈥檚 most notable awards for early-career faculty, recognizing researchers who integrate innovative research with education and community engagement.

Starting July 1, the Hawaiʻi community can receive free, personalized monthly climate updates tailored specifically to their own neighborhood or coastline delivered straight to their inbox. Developed by the University of 贬补飞补颈ʻ颈鈥檚 Hawaiʻi Climate Data Portal (HCDP), the new Monthly Climate Summary tool translates complex scientific metrics into highly localized, plain-language updates on rainfall, temperature and drought conditions.

Whether you are a rancher monitoring drought signs, a water manager tracking watershed health, a teacher looking for real-world classroom data, or a resident wanting to stay connected to a beloved valley, the tool brings high-resolution climate data directly to the community.

“Not everyone understands how much rainfall typically falls in their area of interest,” said Ryan Longman, director of HCDP and Pacific Islands Climate Adaptation Science Center (PI-CASC) University Consortium program director at (Hawaiʻi Sea Grant). “But if you let them know that it was 50% below normal, or that it was the third driest month in the last century; that鈥檚 the type of information that anyone can understand.”

Tailoring data to traditional boundaries

Subscribers can customize their summaries using traditional Hawaiian geographic boundaries—moku and ahupuaʻa—as well as standard climate divisions and watershed boundaries. This reflects the HCDP team’s commitment to making data meaningful within the state鈥檚 unique cultural and ecological landscape.

To sign up, users can visit the HCDP Climate Summary page, select an area of interest on an interactive map, and enter their email address. Users can subscribe to multiple locations. Each month, they will receive localized climate overviews alongside access to an online dashboard for digging deeper into current and historical trends.

“We wanted end users to be able to connect with the data from the places that meant the most to them,” said Cherryle Heu, HCDP climate data analyst and lead climate summary developer. “When you select a point on the map the numbers will update to tell you exactly what is going on at that location. Given that 贬补飞补颈ʻ颈鈥檚 climate is so diverse, this type of tool allows for local insights that a single statewide average can鈥檛 capture.”

Community-backed resilience

The tool’s development was initially funded by NOAA鈥檚 National Integrated Drought Information System until the grant was canceled in December 2025.

“We were too far along to stop,” Longman said. Support from the DLNR Commission on Water Resource Management allowed the team to complete the tool, a grant from PI-CASC helped support outreach efforts, and the NSF EPSCoR Change Hawaiʻi project provided the cyberinfrastructure foundation that makes it all run.

The HCDP team consists of several grant researchers based in Hawaiʻi Sea Grant and the 糖心视频 Water Resources Research Center. The Pacific Drought Knowledge Exchange Team also led this effort along with collaborators across the state who helped shape the final product.

More than 2 trillion gallons of water鈥攅nough to fill 3 million Olympic-sized swimming pools鈥攊nundated 贬补飞补颈驶颈 in March. The accumulated rainfall over 14 days reached as high as 3,000% of normal historical levels for this time of year, culminating in a destructive 鈥渞ain bomb鈥� over 翱驶补丑耻. Through the University of 贬补飞补颈驶颈鈥檚 贬补飞补颈驶颈 Mesonet and the 贬补飞补颈驶颈 Climate Data Portal, researchers captured the scale of these back-to-back Kona low systems, mapping localized threats and providing crucial data on the state’s severe flooding.

Between March 1 and March 23, statewide rainfall averaged 18.25 inches鈥攎ore than 2.6 times the standard March average of 6.85 inches.

While the first storm (March 10鈥�16) brought hurricane-force wind gusts of 135.4 mph to 贬补飞补颈驶颈 Island and up to 62 inches of rain to Maui, the second Kona storm between March 19 and 23 triggered a new wave of devastation. The second storm dumped up to 61 inches of rain in localized areas, producing destructive floods across eastern and central 惭辞濒辞办补驶颈, West Maui and 翱驶补丑耻.

Communities such as Waialua and Haleiwa on 翱驶补丑耻鈥檚 north shore experienced devastating inundation. 贬补飞补颈驶颈 Mesonet stations highlighted the widespread intensity of the storm: the 碍补驶补濒补 station recorded the island’s highest two-day rainfall of roughly 22 inches, including 19.67 inches in a 24-hour period beginning the evening of March 19. Almost simultaneously, the nearby 碍补濒补丑别驶别 Ridge station above Waimea Valley recorded 9.75 inches in 24 hours.

惭腻苍辞补, Palolo flash floods

As the two-week rainy period neared its end, an intense, localized atmospheric event struck 惭腻苍辞补 and Palolo valleys on March 23. Honolulu Mayor Rick Blangiardi described it as a 鈥渃lassic rain bomb,鈥� heavy rain caused by a stationary storm cell. This 鈥渞ain bomb,鈥� over 惭腻苍辞补 and Palolo valleys, dropped 2 to 4 inches of rain per hour.

Six 贬补飞补颈驶颈 Mesonet stations in the Nu驶uanu-惭腻苍辞补 area recorded between 3.5 and 6.5 inches of rain, the majority of which fell within a three-hour window. Falling on already saturated ground, this turned streams into raging torrents and triggered significant flash floods.

The 贬补飞补颈驶颈 Mesonet, a statewide network of state-of-the-art weather stations, is proving to be a critical source of weather information, especially valuable during extreme events.

鈥淲e are building the mesonet to serve multiple purposes, including research, resource management, support for farmers and ranchers, and others,鈥� said Thomas Giambelluca, 贬补飞补颈驶颈 Mesonet project lead, and former director of the 糖心视频 Water Resources Research Center. 鈥淏ut, providing data when and where it is most needed before and during extreme events like floods and wildfires, might be its most important purpose. Mesonet data will make us better prepared for future events by improving weather forecasts and enabling emergency managers to plan for and respond to extremes.鈥�

Across the state, thousands of Hawaiʻi students spend months investigating scientific questions and testing engineering designs for school, district and . Behind these projects are University of Hawaiʻi mentorship, expert judging and resources that turn classroom concepts into real-world research.

Connecting to real-world research

Science fair projects provide an opportunity to extend classroom learning. Radford High School science teacher Daniella Griffay borrowed from 糖心视频 to teach wave speed and propagation. This led to a connection with Troy Heitmann, assistant researcher at 糖心视频鈥檚 , who mentored Radford student John Phillip English, on improving the magnets used in .

“This project provided a meaningful opportunity for a student to explore renewable energy technology while developing scientific reasoning, engineering design skills and experimental problem-solving experience,” said Heitmann.

In addition to Heitmann鈥檚 mentorship, English used resources developed by STEM Pre-Academy, with support from undergraduate student intern Erik Bendickson.

“The big thing that I learned from the science fair was despite things not going how you plan, it’s just important to be able to bounce back from that and be able to continue to work on something,” English said. “I think that more students honestly should work with professors at 糖心视频. It just gives you a different understanding of things. [Heitmann] would introduce a topic and he would explain it in a simple way and then he would build it up to what was more complicated. He went out of his way to make sure that I was progressing well with the project.”

“I’m not an engineer and needed guidance on how to support this student on their project,” said Griffay. “I am truly grateful not just for the equipment in the lending library but also for the collaborations and expert knowledge.”

Another two of Griffay鈥檚 students were connected by STEM Pre-Academy to a 糖心视频 mentor, Associate Researcher Marek Kirs from 糖心视频鈥檚 . Kirs worked with students Maddison Soria and Skye Gussenhoven in their second year of a project, teaching them to cultivate bacteria and perform disk diffusion assays.

English, Soria and Gussenhoven advanced out of the Central District Science Fair and are headed to the Hawaiʻi State Science Fair in April.

For University of Hawaiʻi at Mānoa PhD student Brian Gorberg, the devastating Kona low storms weren’t just an academic research topic—they were a recurring nightmare that inundated his home three times in less than four weeks. Renting the bottom bedroom of a home in Waialua on Oʻahu’s north shore, Gorberg witnessed the final and most severe flood send an 8-foot wall of water through his place.

After experiencing two recent floods that ruined his belongings, Gorberg was seeking refuge at a friend’s house down the street when the third flood hit. The flash flooding was catastrophic, acting like a “dam spillway” through his neighborhood. The water destroyed his Jeep Patriot given to him by his dad, caused a neighboring house to spin off its foundation, and trapped another neighbor in neck-deep water.

“I got woken up by a giant wave,” Gorberg said. “I assumed the worst because I study hydrology. I assumed the dam failed and I knew I had to get out of the watershed. So, I drove all the way to the evacuation site. I actually ran up the hill because I didn’t believe the evacuation site was safe enough.”

Flooding expertise proved critical

Gorberg’s academic background proved critical during the floods. As an student in the and working with the under advisor Chris Shuler, his expertise allowed him to understand the mechanics of the disaster. During the floods, Gorberg spent hours walking through his neighborhood trying to warn residents ahead of the rising waters.

Gorberg鈥檚 current research work is to create high-end, reproducible flood models and stage height maps to better protect local communities. Working alongside undergraduate students Chiara Duyn, Megan Wong and Anne Dominique, Gorberg created a that provides residents with transparent, scenario-based flood information.

While the app and Gorberg鈥檚 maps currently focus on Windward 翱驶补丑耻 watersheds such as Kāneʻohe, the underlying flood models are designed to be reproducible, and Gorberg aims to eventually expand this mapping to any flood zone across Hawaiʻi. The flood maps simulate exact inundation levels when local streams breach their banks at incremental heights—such as 12, 13 or 14 feet—allowing communities to visualize their risk and prepare for an approaching storm.

Reflecting on the tools he is building, Gorberg emphasized the urgent need for better preparedness in Hawaiʻi.

“Every stream gauge in the mainland has these maps. It’s not fair that Hawaiʻi doesn’t have it, especially considering these events,“ Gorberg said. ”And because there are graduate students like myself who have created this… that’s like the missing link in Hawaiʻi that would honestly solve this event, or would have been different if we had those maps.”

A new (NASEM) is urging clinicians to prioritize ongoing symptom evaluation and continuity of care for individuals potentially exposed to jet fuel contaminated drinking water on Oʻahu in 2021.

The report examined health risks tied to leaks of JP-5 fuel from the Red Hill Bulk Fuel Storage Facility that affected the water supply serving Joint Base Pearl Harbor-Hickam and nearby communities. As many as 93,000 people may have been exposed to the jet fuel through drinking water, inhalation of vapors or skin contact.

University of Hawaiʻi at Mānoa (JABSOM) Dean Emeritus Jerris R. Hedges, JABSOM Chair and Professor Joseph Keaweʻaimoku Kaholokula, JABSOM graduate and clinical faculty member Marcus Kawika Iwane, and JABSOM graduate and 糖心视频 West Oʻahu Professor Ricardo Custodio served on the 16-member multi-disciplinary National Academies “committee on the clinical follow-up and care for those impacted by the JP-5 releases at Red Hill,” which authored this report. 糖心视频 Mānoa Professor of Public Health Sciences Catherine Pirkle and Assistant Professor Aurora Kagawa-Viviani served on the multi-disciplinary peer-review team.

Key NASEM report findings

Researchers found limited evidence linking exposure to short-term respiratory, gastrointestinal, skin and mental health symptoms. However, data remains insufficient to determine specific long-term health effects, and no validated medical tests exist to confirm past exposure or the extent of exposure. As a result, the report recommends clinicians carefully document patient histories and symptoms while ensuring ongoing, patient-centered care.

The report also calls for expanded research and improved environmental monitoring to better understand exposure levels and potential health outcomes. Recommendations include developing biomarkers to detect jet fuel exposure, standardizing water testing methods and conducting long-term studies of exposed populations.

“This report highlights the importance of a registry to collect long-term health information to fill the gaps in truly understanding how JP-5 exposure may impact the community over time,” Kaholokula said. “The more people who enroll in the , the more impactful the research and information becomes.”

“Continued enrollment in the Red Hill Registry and similar programs is critical for future studies and research,” Hedges said. “Such registries will provide important additional knowledge related to the exposure, especially regarding potential long-term effects on women and children.”

The report further highlights the need for improved coordination among federal, state and local agencies to ensure drinking water safety and rebuild public trust following the contamination incident.

“The release of this report reminds families that even though we are removed in time from the May 2021 and November 2021 fuel spills, the voices of the individuals and families who lived through the water crisis are still being heard,” said Rosana “Sanie” Weldon, director of the Red Hill Registry. “By enrolling in the Red Hill Registry, whether you had symptoms or not, you help researchers establish accurate baseline data, detect even small health differences which may present years from now, and ensure that findings truly reflect the whole community.”

Importance of Red Hill Registry

The Red Hill Registry aims to track health outcomes and provide resources and education for those who experienced jet fuel in their drinking water from the Red Hill Bulk Fuel Storage Facility. Based in the at 糖心视频, the registry has dozens of partners supporting the registry from across the 糖心视频 System with technology infrastructure, data security, questionnaire integrity, clinical guidance, water science and more.

From 135 mph wind gusts on Hawaiʻi Island to 62 inches of rainfall on Maui, a recent Kona low system brought weather conditions usually reserved for major hurricanes to the state. These extreme totals were captured by the University of 贬补飞补颈ʻ颈鈥檚 Hawaiʻi Mesonet, a weather monitoring system that is mapping localized threats across areas that previously had no data available. 糖心视频鈥檚 Hawaiʻi Climate Data Portal team created a report on the storm.

Alongside immense flooding, the storm brought destructive winds. The Hawaiʻi Mesonet station at Kaiāulu Puʻuwaʻawaʻa on Hawaiʻi Island recorded a maximum wind gust of 135.4 mph. Winds were briefly sustained at speeds equivalent to a Category 2 hurricane, averaging 105 mph over a 15-minute period.

Maui was hit the hardest, with peak rainfall totals reaching 62 inches in localized regions. Hawaiʻi Island also saw heavy precipitation, with areas recording 16–32 inches, and isolated spots also nearing 62 inches. Both Kauaʻi and Oʻahu recorded maximum totals ranging 16–32 inches. Molokaʻi and Lānaʻi experienced peak amounts 4–16 inches.

The upper elevations of Haleakalā experienced the most extreme rainfall, with 33.2 inches falling during the 24-hr period beginning March 13 at 8:30 a.m., nearly double the highest 24-hr rainfall previously recorded there. That amount is much greater than the NOAA‘s official estimate of 19.7 inches in 24 hours for the 1000-year storm (the rainfall amount with a 0.1% chance of being equalled or exceeded in any given year). Rainfall was even higher at the Kuiki Hawaiʻi Mesonet station on the east rim of Haleakalā crater with 36 inches falling in 24 hours beginning at 6 p.m. on March 13. This amount exceeded the NOAA 24-hr 1000-year extreme rainfall estimate of 28.5 inches.

“Before the project began, Hawaiʻi was one of only 20 states without a comprehensive statewide weather monitoring system, meaning we previously had no access to information in many of these areas,” said Tom Giambelluca, Hawaiʻi Mesonet project lead, and former director of the 糖心视频 Water Resources Research Center. “Now, the system is constantly collecting data on rainfall, soil moisture, and other weather variables that can tell us in real time if an area is highly susceptible to fires or flooding, which ultimately allows us to be as prepared as possible”

To make this information accessible, 糖心视频 launched a real-time weather dashboard offering public access to live weather data from more than 70 monitoring stations currently active across the state. The dashboard updates data every 15 minutes, allowing users to view current, localized conditions including temperature, rainfall, wind, humidity, solar radiation and soil moisture. This creates one of the most comprehensive and timely weather resources available in Hawaiʻi.

The University of Hawaiʻi at Mānoa is expanding its environmental monitoring and research capabilities thanks to a $30,000 donation from the Hawaiʻi Water Environment Association (HWEA).

The HWEA gift will help upgrade the college鈥檚 environmental engineering lab through the acquisition of advanced instruments—most notably a state-of-the-art gas chromatograph system that acts like a high-tech “nose” that can sniff out and measure different gases in the air—expanding 糖心视频鈥檚 ability to analyze environmental samples with higher precision. The measurement of greenhouse gases such as methane, carbon dioxide and nitrous oxide, as well as compounds tied to odor and corrosion concerns, are key issues for wastewater facilities, community health and regulatory compliance.

“This gift is a vital investment in the research and education capacity of our Environmental Biotechnology Research Group at the University of Hawaiʻi at 惭腻苍辞补,” said Zhiyue Wang, assistant professor in the and the . “By supporting everything from the acquisition of advanced analytical equipment and software to student travel and professional seminars, these resources allow us to maintain the high-level technology and scholarly records necessary to solve Hawaiʻi鈥檚 most pressing environmental challenges.”

The upgraded instruments will also provide new learning opportunities for students through lab instruction, capstone projects and research experiences involving advanced analytical techniques used across commercial and municipal laboratories. It also opens the door for deeper collaboration and knowledge exchange between 糖心视频 and water environment professionals statewide, including potential lab tours, seminars and shared learning opportunities.

The lab鈥檚 enhanced capabilities align with HWEA鈥檚 mission to protect and enhance Hawaiʻi鈥檚 water environment by supporting research at the intersection of air and water quality and by helping train the future workforce in modern analytical methods.

University of Hawaiʻi at Mānoa researchers are part of a team that was recently awarded a (NSF) to address the environmental and public health impacts of outdated wastewater infrastructure in island communities. The project is led by the University of South Florida, with 糖心视频 Mānoa playing a key role in research and pilot testing.

Focus on Hawaiʻi鈥檚 water health

In Hawaiʻi alone, an estimated 83,000 cesspools discharge approximately 52 million gallons of untreated wastewater into the ground each day, contaminating coastal waters and damaging coral reefs. Replacing cesspools with approved wastewater systems could cost households $30,000 to $50,000.

The Honu Hub project seeks to ease that burden by developing a solar-powered, compact and certifiable alternative that protects both human health and the environment. These systems are energy-independent and equipped with remote monitoring and automation, making them suitable for cesspool replacement in low-density and isolated areas. The “Honu Hub” represents a new class of small, adaptive and decentralized wastewater infrastructure.

By centering the work in Hawaiʻi, the research team ensures the technology is designed to overcome local challenges, including poor soils, high water tables and saltwater intrusion. The goal is to create a solution that can be adopted throughout the U.S. Pacific region and the continental U.S.

糖心视频 Mānoa researchers are leading the design and real-world pilot demonstration of nutrient capture systems within the Honu Hub. Pilot testing is taking place at the Wahiawā Wastewater Treatment Plant, in collaboration with the City and County of Honolulu.

The award supports the Honu project within NSF鈥檚 Convergence Accelerator program, which aims to develop adaptive, decentralized wastewater infrastructure solutions for island and rural communities facing severe sanitation challenges.

Zhiyue Wang, the project鈥檚 co-principal investigator and assistant professor at 糖心视频 惭ā苍辞补鈥檚 and in the , will assist with the pilot testing of Honu Hub in Hawaiʻi and developing novel technologies for nutrient recovery in the system.

“Collaborating with the University of South Florida, our goal is to empower communities with solutions that protect public health, preserve our nearshore ecosystems and ensure clean water for future generations,” Wang said.

Tao Yan, director of the Water Resources Research Center, is also part of the Honu research team. Wang is working alongside principal investigator Daniel Yeh (University of South Florida), co-principal investigator Stuart Coleman (Wastewater Alternatives and Innovations) and co-principal investigator Allan Smith (Swiftwater Solutions).

To better protect Hawaiʻi鈥檚 people and ecosystems from threats, such as wildfires, drought, flooding, hurricanes, tsunamis, water contamination and more, University of Hawaiʻi at 惭腻苍辞补 and Georgia Tech researchers have secured a to build faster, cheaper, locally made sensors that deliver potentially life-saving data in real-time.

The funding will support the development of low-cost sensors that can be printed in minutes and deployed the same day to collect actionable data for communities and organizations across the state. These sensors could measure water quality or soil contamination signals, and then connect to an AI-enabled handheld device smaller than a cell phone, that processes and transmits data to the web in real-time. Users could then view and interpret the data via a publicly available dashboard.

Community kuleana

To ensure its success, the technology will be co-designed with groups who have kuleana (responsibility) for communities, land and water across Hawaiʻi, including land stewardship organizations, Hawaiian-language immersion schools and community colleges. These ʻ腻颈苍补 (land) stewards, k奴puna (elders), residents and kumu (teachers and educators) will guide priorities, experiment with prototypes and define success criteria.

“We can shorten the path from idea to instrument and build sensors tuned to local priorities without relying on centralized, hard-to-access facilities,” said principal investigator and 糖心视频 惭腻苍辞补 Associate Professor . “Our goal is a design-to-deployment pathway that works on-island: robust, affordable and replicable.”

The team is developing the sensors to pair with a small, durable edge device that can harvest and store energy, run machine learning models and work even with limited network connectivity. An open library of circuits and firmware will let partners quickly customize sensors for measuring targets from pH and turbidity to heavy metals and contaminants.

“This grant recognizes that Hawaiʻi is a key leader in the proper design of disaster and hazard response cyberinfrastructure,” said Josiah Hester, a Kanaka ʻ艑颈飞颈 (Native Hawaiian) and associate professor of computing at Georgia Tech. “Deploying AI devices in austere environments, making AI interpretable and understandable, and providing these capabilities to everyone are key goals we will achieve. As a Native Hawaiian scientist and technologist, it is my own kuleana to translate these technologies that support stewardship, and we as a team are excited to see this work support our communities.”

Building on community ties

The project grows from existing relationships across Oʻahu, Maui and Kauaʻi, including Hawaiian-language immersion schools and stewardship organizations, where residents, educators and resource stewards will guide priorities. The team will convene iterative design workshops, peer exchanges between partner sites on Oʻahu and Maui, and a capstone gathering to synthesize findings and share open designs. Data governance will follow established frameworks to support local control and appropriate confidentiality for sensitive results.

“Our approach follows advances in community-centered co-design where we will design the sensing agenda together with community partners,” added co-principal investigator Aurora Kagawa-Viviani, assistant professor in 糖心视频 惭腻苍辞补鈥檚 and in the . “Building strong and equitable relationships ensures the technology and the data it produces have lasting value long after the prototype. Our design process considers who maintains it, how the data are stewarded, interpreted and made useful for community decision-making.”

The grant will support hands-on training that connects students across K–12, community colleges and research universities with partner sites. The team鈥檚 open hardware, software and design artifacts will be released for others to adapt in island, rural and urban settings facing similar hazards.

Most people who were affected by the November 2021 Red Hill fuel spill continued to experience physical, emotional, social and/or financial impacts more than 20 months after the incident, according to a released October 15, 2025, by the University of Hawaiʻi Economic Research Organization (糖心视频ERO).

The report provides results from a follow-up self-administered online survey conducted in July 2023 (20 months after the spill) with 174 people who had participated in earlier studies by the Centers for Disease Control and Prevention.

Main findings reported in 2023

Ongoing physical and mental health impacts:

• About three quarters (79%) of respondents reported one or more new or worsening physical and/or mental health symptoms since the 2021 fuel spill.
• A majority (68%) reported ongoing symptoms in 2023, nearly two years after the spill.
• Nearly half of respondents (49%) continued to suffer from mental health impacts, followed by neurological symptoms (44%), gastrointestinal issues (36%) and skin/eye symptoms (34%).

Healthcare response:

• The majority (65%) of respondents sought medical care related to the spill.
• Experiences with medical care were mixed: 24% of respondents rated the medical care they received for their exposure to the fuel spill as excellent or good whereas 36% rated their care as bad or very bad.
• More than 50% of respondents said they have a great deal of trust in their healthcare provider to provide correct information; less than 5% said they have no trust.
• The vast majority of open-ended responses about healthcare described dismissed concerns, insufficient documentation of symptoms, inadequate testing options and challenges accessing specialists.

Social and economic impacts:

• Many reported feelings of isolation as a result of health impacts and disaster response.
• Some respondents also pointed to ways that the community organized and supported one another in disaster response.
• Some (18%) reported income loss (median = $13,750 annual income), while the majority (82%) incurred additional out-of-pocket expenses (median = $8,200).
• Only 12% of those with out-of-pocket expenses said they were fully reimbursed, and more than a third (36%) said they received nothing at all.

Institutional trust and perceptions of institutional crisis response:

• Respondents were most satisfied with how the Honolulu Board of Water Supply responded to the crisis and least satisfied with the response of the Navy.
• Many expressed feelings of betrayal, particularly toward the Navy. Many respondents said they felt lied to about the safety of the water, and cited inadequate medical and other crisis response as factors undermining trust.
• Participants discussed a need for greater transparency, accountability and empathy in future crisis response.

“Findings reveal significant and ongoing well-being impacts including physical and mental health challenges, disruptions to social networks and relationships and financial losses,” the study wrote.

Low pay, limited advancement opportunities, and a small applicant pool for specialized positions are among the biggest challenges facing Hawaiʻi鈥檚 water sector, according to a new University of Hawaiʻi report. The study also found a strong commitment among water professionals to public service and community well-being, and highlighted opportunities for 糖心视频 to help strengthen education and career pathways that support a thriving water future for the state.

The report, published October 8, shares insights from 43 representatives from federal, state and county agencies, as well as private and nonprofit organizations. The findings emphasized the need for both technical expertise and a holistic understanding of the political, cultural, economic and historical dimensions of water in Hawaiʻi.

One key finding was, “Many suggested that the University of Hawaiʻi has an important role to play in convening organizations and people across the water sector and in conducting applied and policy relevant research.”

Interviewees cited recruitment and retention challenges driven by low salaries and slow hiring processes, along with a need for more training in specialized areas such as engineering, hydrogeology and aquatic biology. Many also noted that institutional culture and job descriptions do not always effectively attract local candidates with lived experience and a commitment to mālama ʻ腻颈苍补, or caring for the land. The research highlighted the importance of comprehensive, practical training in communication, project management, fieldwork and community engagement.

The report represents the first phase of a collaborative project involving the (糖心视频ERO), , , and .

Funded by the Hawaiian Islands Environmental Finance Center of the Hawaiʻi Community Foundation, the next phase will focus on interviews with 糖心视频 departments and professional development programs to identify assets, gaps and best practices for water-related education and careers statewide.
