Drinking Water Quality Testing


To assure the quality of drinking water supplies by testing for chemical and microbiological contaminants.

What we do

  • Identify and quantify chemical and microbiological contaminants in public drinking water supplies as mandated by the federal Safe Drinking Water Act and state regulations.
  • Test private well water samples submitted by homeowners using the same methodology to ensure safe potable water supplies for individual homes.
  • Participate in the national Environmental Response Laboratory Network (ERLN) and the Water Laboratory Alliance (WLA), a network of laboratories qualified to provide water testing support to the EPA, states and municipalities in response to incidents of contamination that impair public water supplies.


  • Established the capability to analyze perfluoro- and polyfluoro- alkyl substituted compounds in drinking water and well water samples to respond to new drinking water advisories.
  • Certified by the USEPA for the chemical and microbiological analysis of drinking water using approved methods according to the Safe Drinking Water Act.
  • Established the capability to identify harmful algae and analyze cyanotoxins produced during harmful algal blooms in public water supplies.
