When Should You Get Your Water Tested?

You should consider independent water testing if you rely on a private well (not regulated by the EPA), if you have an infant or are pregnant, if your home was built before 1986 (possible lead pipes), if you notice unusual taste, odor, or color, or if your area has experienced a recent contamination event or natural disaster.

All laboratories in this directory are certified by their state’s drinking water program and accredited to test samples for compliance with EPA National Primary Drinking Water Regulations.
