ILRP Drinking Water Well Monitoring
In accordance with Waste Discharge Requirements for Growers in Coalition Groups, coalition members are required to monitor their on-farm drinking water wells. This is to identify wells that have nitrate concentrations exceeding the drinking water standard and to notify well users of the potential for human health risks. For questions regarding this monitoring, please contact Robert Ditto at Robert.Ditto@waterboards.ca.gov.
