Drinking Water Well Monitoring Program

Drinking Water Well Monitoring is starting in January 2022.  If you have a drinking water well on a parcel enrolled in the ILRP actively used for drinking and cooking and you answered the question on the farm evaluation survey as having at least one well, you can expect a letter from the Regional Water Quality Control Board sometime after January 2022.
