Illinois American Water Delivers Additional PFAS Settlement Credit to Customers

Latest credit of over $15 brings total settlement refunds to more than $80 per customer while the company continues PFAS treatment upgrades across Illinois

BELLEVILLE, Ill., Aug. 27, 2026 /PRNewswire/ -- Illinois American Water announced that additional credits were recently applied to customers' bills as a result of the company's receipt of proceeds from settlements reached with manufacturers of per- and polyfluoroalkyl substances (PFAS).

On August 10, 2026, Illinois American Water issued a $15.02 bill credit to all active water customer accounts as of June 30, 2026. The credit distributed to customers in total was $4.7 million from recent settlement proceeds the company received from PFAS manufacturers.

The first bill credit of $17 million total for eligible Illinois American Water customers occurred in November 2025 followed by a second credit in February 2026 of $3.2 million total. With this latest credit, $24.9 million total has been returned to eligible Illinois American Water customers through PFAS-related settlements. Eligible accounts active during all three distributions have received a total of $82.40 per account to date.

The credit is made possible through Illinois Commerce Commission (ICC) approval of Illinois American Water's PFAS Litigation Universal Credit Rider, which allows the company to provide PFAS settlement proceeds directly to customers as they are received. The credits are applied to all active customer accounts and are not based on any level of PFAS detected in a customer's water.

The company is committed to complying with all drinking water standards and is taking appropriate actions to meet new PFAS regulations as they are implemented. The company has completed PFAS treatment upgrades in several communities and plans to invest approximately $92 million to expand PFAS treatment across multiple water systems throughout Illinois through 2029.
