DPR Is Offering Free, At-Home Well Testing Kits

Do you get your water from a well on your property?

Have you ever wondered if there are pesticides in that water?

The Department of Pesticide Regulation is offering free, at-home well testing kits to hundreds of Californians.

This information is added to the department’s broader database of groundwater sampling to inform any regulatory or mitigation measures needed to protect our groundwater. DPR scientists routinely monitor hundreds of wells throughout the state in agricultural areas. For the first time, DPR is offering these at-home kits to increase the sampling of wells in areas across the entire state.

How it Works

Kit recipients will receive a box with equipment and detailed instructions to collect and return water samples. DPR will cover costs for shipping samples and will use the samples provided to analyze well water from across California. Limited kits are available.

Results will be provided to the volunteers within 2-5 months.

Request a Sample Kit

To request one of the kits, send your name, address, and phone number to GWPP@cdpr.ca.gov or call (916) 445-2262. A Spanish- or English-speaking staff member will respond to arrange shipping a kit.

To arrange a group sampling/shipment, email DPR at the above address.
