The Lab You Can Trust With Results That Matter

Water Analysis

We specialize in drinking water, irrigation water, waste water, and industrial water analysis.

It can be tricky to know exactly just what water test you need for your application.Whether it be a public water source or samples needed to fulfill GAP requirements, we can help. Please contact one of our water experts to help find the tests that suit your need.

Quality control is very important to us. Our lab adheres to the 2009 TNI standard and carries accreditation through:

Washington State Department of Ecology (WSDOE)
Washington State Department of Health (WSDOH)
State of Oregon through their environmental laboratory accreditation program (ELAP).

We have sampling kits available. Please note the hold time requirements for each analysis.
