Community Water Supply Testing Program

The Illinois EPA laboratory is offering drinking water testing services for your water supply as part of our Community Water Supply Testing Program (CWSTP) for Fiscal Year 2023 (July 1, 2022 through June 30, 2023.) We want your business!  We are your State Laboratory and would like the privilege to perform your required drinking water testing.

Illinois EPA asks that you complete and submit the Participation Form by

This will inform the Agency of your decision to participate in this program. If you elect to participate,
payment MUST be included with the Participation Form. Please make your check payable to Illinois EPA.

Mail your completed Participation Form along with your Payment by May 27, 2022 to:

Illinois Environmental Protection Agency - Lab
825 North Rutledge, 4th Floor
Springfield, IL 62702

Signup Options Available

Check full participation to have 100% of your testing provided by the Illinois EPA using our 3C Customer Satisfaction approach. If our laboratory does not perform the actual analysis, we will coordinate and pay for testing provided by other labs. This means Illinois EPA staff will deal directly with the laboratories and take care of any testing, bottle, or data reporting needs for you.  

When choosing a coliform lab, be sure you keep the distance to the lab  and sample holding time in mind.

By choosing this option you agree not to participate in the program but your supply must still complete all testing requirements and report the results to the Illinois EPA. We ask that you still return the Participation Form and indicate that you choose not to participate .

Electronic Results

Electronic results can be sent to you. If you participate in the program, you have the option of having your results sent to any e-mail address. You can simply send an e-mail with your facility ID# to the Illinois EPA Lab at EPA.Laboratory@illinois.gov. Coliform, Cryptosporidium and Radionuclide results are provided by mail.

CWSTP Benefits

Your annual fee is determined by the drinking water testing required for your supply and the signup options you select. The fee covers the costs of your drinking water analyses for the entire year (July 1, 2022–June 30, 2023).

New Options - Volunteer Testing for Harmful Algal Blooms

The U.S. EPA has issued health advisories for Microcystin and Cylindrospermopsin. The Illinois EPA laboratory has been performing these tests for the past two years and stands ready to help you test both your intake and finished water for these cyanotoxins.
