- EOA, has led the efforts with the ongoing Watching Our Watersheds (WOW) Trash Outfall Monitoring Project (MP) to help achieve trash flow reduction goals required by the Municipal Regional Stormwater NPDES Permit (MRP) 3.0, provision C.8.h.iii. In partnership with and across several countywide programs during the 2024-2025 work year, EOA:
- Sampled three storm events at 10 monitoring locations and collected 30 samples using trash net devices for trash sampling and monitoring water flow with water level sensors in outfall pipes.
- Performed qualitative assessments of catchment areas, including observations of trash sources and trash controls.
- Categorizing and measuring total trash collected per catchment area during each storm event.
- Calculated annual trash loading rates per catchment site based on average trash volume per sampled wet weather event, water flow data per wet weather event and total events in a rainy season.
The work performed by EOA, on behalf of clients identified successful compliance to the MRP and identified specific areas of focus for the 2025 Work Year.
