Requirements for residential water testing

In general, there are no requirements for testing residential water sources. The Environmental Protection Agency and most states don’t require residents to routinely test their private drinking or domestic water sources for contaminants.

However, other entities may require testing or individuals may want their drinking water or agricultural water analyzed for potential contaminants. Some common reasons individuals get their water tested:

  • Real estate transactions – For loan requirements or a buyer’s confidence that the water is safe to drink.
  • New water wells – To test for a standard “new well” construction parameter suite.
  • Hydraulic fracturing processes – To test for contamination of injected chemicals in a groundwater aquifer source.
  • Stormwater pollution – To test for nutrient run-off from agricultural areas or sources that contain a high nutrient content like fertilizers.
  • Bacteria (E. coli.) – To confirm purchased drinking water is free of bacteria.
