Drinking Water Well Monitoring

Description / purpose

On 7 February 2018 the State Water Board revised the Waste Discharge Requirements (Order) for the Eastern San Joaquin River Watershed. The revised Order includes a new drinking water well monitoring requirement. Beginning 1 January 2019, East San Joaquin Water Quality Coalition (ESJWQC) members must monitor drinking water wells on enrolled parcels for nitrates. High levels of nitrates found in drinking water wells impact public health. Excess nitrates (NO3) in soil are often found in rural and agricultural areas. The most common sources of nitrate are fertilizer, livestock waste, and septic systems. Nitrates in soil are highly mobile and can be easily transported to groundwater. The purpose of Drinking Water Well Monitoring is to identify drinking water wells that have nitrate concentrations exceeding the drinking water standard and notify any well users of the potential health risks.
