Where can I have my drinking water tested for pesticides?

The answer depends on whether your water comes from a well on your property or public water supply company, and the type of pesticide contamination you believe may be present.

1. If your water is from a public water supply, contact your water supplier or the state drinking water office located in your state environmental agency. They can tell you whether your water is regularly tested for that type of pesticide and how much, if any, has ever been found.
   
2. If you have a private well or if your water has not been tested for that type of pesticide, contact your state pesticide program. They can assist you in determining whether testing is warranted, choosing the type of analysis to be performed, identify laboratories capable of performing the analysis, and determining the significance of testing results.
