Wastewater Quality
In order to protect public health and the Napa River, NapaSan is required to meet stringent water quality regulations. At our treatment plant, we operate a water quality laboratory that constantly monitors the wastewater as it undergoes treatment and after treatment is complete. The NapaSan laboratory also uses commercial laboratories with high tech equipment that perform analyses capable of detecting some pollutants down to parts per trillion.
Tests
The lab conducts over 26,000 tests each year to identify a variety of wastewater constituents, including conventional pollutants, metals, toxic organic compounds, and pathogens.
