If you get your drinking water from a private water supply - such as a water well, cistern, spring, pond,  or rainwater system -  the U.S. Environmental Protection Agency (EPA) highly recommends periodic testing of your water.

LCRA's Environmental Laboratory Services (ELS) is certified by the Texas Commission on Environmental Quality (TCEQ) for drinking water testing.  ELS offers the general public affordable testing of their residential water supply for common contaminants identified by the EPA. ELS can test your water for any or all of these contaminants.
