The Community Water Supply Testing Program has the same options we have included in the past:

Signup is for one year. Water systems can elect to participate in the program for one year. The annual program allows Illinois EPA to better evaluate your testing requirements for the year and enables the Agency to establish fees that reflect the most accurate costs possible. This one-year period begins July 1, 2015 and ends June 30, 2016.

Signup Options

Full Participation.

Choosing full participation includes all drinking water testing required for a CWS for the upcoming year. If the Illinois EPA laboratory does not perform the actual analysis, staff will arrange for the analysis to be performed by another laboratory and Illinois EPA will pay for those tests from the fees we collect. The Illinois EPA staff will deal directly with the laboratories and take care of any testing, bottle or data reporting issues for you.

Important: When choosing a coliform lab, be sure you have a method of getting the samples to that lab to ensure all holding times can be met.

Partial Participation.

By choosing this option, a CWS only needs to commit to a minimum of having the chemical analysis performed by the Illinois EPA laboratory. A CWS can choose to opt in or opt out of the program for other tests such as Coliform, Cryptosporidium or Radionuclide testing. The fee will be based only on the analyses that will be performed as part of the CWSTP.

If a CWS chooses the partial participation option, the CWS will pay the Coliform, Cryptosporidium or Radionuclide labs directly. The other lab will need to supply the CWS with the necessary bottles and shipping containers as well as handle the data reporting. If a CWS decides to opt out for any of the testing referred to in this section, please make sure that the lab chosen is certified.

No participation.

By choosing this option, a CWS elects to not have the Illinois EPA laboratory perform their required drinking water analyses and uses another certified lab to complete all testing requirements and report the results to the Illinois EPA.

Note: To avoid any potential violation due to disruption in receiving needed sample bottles for the upcoming sampling period (starting July 1, 2015), Community Water Supplies must submit the Election Form along with your payment as soon as possible (by May 30, 2015).

Electronic Results

Electronic results can be sent to you.

When a CWS participates in the program, the CWS will have the option of having results sent to any e-mail address. Simply choose this option on the Election Form or send a current email address to or Currently only results for chemical analyses performed by the Illinois EPA laboratory are provided electronically. Coliform, Cryptosporidium and Radionuclide results are provided by mail.

Illinois EPA has retained CWSTP Benefits

Annual Fee.

The annual fee is determined by the scheduled drinking water testing specific to each CWS and the signup options selected. This fee covers the costs of drinking water analyses for the entire year (July 1, 2015 – June 30, 2016).

No Added Fees.

If a CWS chooses to have the Illinois EPA laboratory provide the testing for Cryptosporidium or Radionuclide a contracted lab will be utilized, but the Agency will only charge the amount that the other laboratory charges. The Illinois EPA laboratory does not add a processing fee and will oversee all data reporting and bottle issues for the CWS.
