Drinking water Information

As a laboratory we are often contacted by individuals who want to know if their drinking water is safe, but do not know what to test for. Unfortunately, we cannot advise clients on what to test for. To help clients identify their testing needs we have compiled this list of resources.

Environmental Protection Agency: Drinking Water Regulations

The EPA’s website provides helpful information about ground water & drinking water regulations. 

The EPA’s National Primary Drinking Water Regulations include an extensive list of contaminants that have health risks associated with them. This list is helpful when determining what to test for. Most contaminants on the list can be eliminated based on the common sources listed.

Texas A&M's AgriLife Extension

Texas A&M's AgriLife Extension website provides helpful information for Texas well owners.
