The City of Alameda conducts water quality monitoring through the Alameda County Clean Water Program to assess water quality conditions, track pollutants, and evaluate stormwater impacts on local creeks and the San Francisco Bay. Monitoring supports compliance with the Municipal Regional Stormwater Permit (MRP) and provides a consistent basis for understanding conditions and trends over time.
What We Monitor
The Clean Water Program conducts a range of monitoring activities to evaluate water quality conditions, track priority pollutants, and assess stormwater-related impacts in urban watersheds.
- Low Impact Development (LID) features are designed to manage stormwater runoff close to where it falls by mimicking natural hydrology and reducing the transport of pollutants to waterways. The Clean Water Program supports LID monitoring to evaluate pollutant removal performance and hydrologic benefits, and to better understand how these features function once constructed and operating.
- Trash is carried by stormwater can harm aquatic life, degrade habitat, and affect community use of local waterways. The Clean Water Program conducts trash monitoring to evaluate the effectiveness of full trash capture devices in reducing trash discharges to creeks and the San Francisco Bay.
- Mercury and Polychlorinated Biphenyls (PCBs) are persistent legacy pollutants that accumulate in sediment and aquatic organisms. Monitoring often includes sediment sampling, which helps identify where these pollutants are present in the urban environment and supports efforts to reduce risks to water quality and public health associated with Bay-caught fish.
- Pesticides detected in local creeks may originate from residential and commercial sources and can be highly toxic to aquatic life. Monitoring helps track the presence of these compounds and supports evaluation of long-term trends in urban waterways.
