In July, Stormwater Maui had the opportunity to be water quality mentors for a UHMC Upward Bound team for their student-led project-based learning assignment. Our presenters discussed the movement of water within an ahupua’a and how stormwater runoff can carry pollutants into surface water bodies. We highlighted common stormwater pollutants such as oil, chemicals, fertilizer, pesticides, and sediment, discussing their typical sources and the impact of large quantities of these pollutants on receiving water bodies.

This session provided students with a unique perspective on how land-based activities contribute to water pollution and encouraged solution-based thinking to prevent contaminated runoff from entering streams and the ocean. Additionally, Stormwater Maui conducted Outfall Site Inspections at Paia Bay and Kahului Harbor, where students learned how to complete our outfall inspection checklist and record visual observations.

Students gained insight into our daily work and the efforts of HDOT Highways to mitigate potential stormwater pollution. They also explored the challenges of stormwater management and designed a prototype to address these issues. Using supplies from our AASHTO STEM Outreach Solutions Environmental Module, students examined water flow and filtration methods, employing different filter fabrics to target various pollutants.

This hands-on experience not only educated students about stormwater pollution but also encouraged them to think innovatively about safeguarding our water resources. HDOT Highways Maui District values the opportunity to support the growth of future leaders and environmental stewards.
