(NEXSTAR) – So-called “forever chemicals” have been found in 45% of the nation’s tap water, according to a recent government study, but is your tap water affected?
If you’re wondering whether or not your tap water might contain synthetic chemicals known as PFAS, nonprofit Environmental Working Group created an interactive map using official records and data from public drinking water systems to show where forever chemicals were found to be above and below the advised maximum concentration level, 4 parts per trillion (PPT).
EWG notes that while researchers used the highest quality data available, contamination levels are based on a single point in time and may not reflect changes to the water system or treatment efforts.

According to the map, Illinois contains 27 public drinking water systems that had forever chemicals above the advised maximum concentration level.
In Central Illinois, the most notable water systems above the maximum level include the Pleasant Valley Public Water District and Illinois American Water, both of which are in Peoria. To the south, the Illinois American Water system in Lincoln was also listed above the maximum level, and to the northwest, Galesburg’s water system was reportedly above that maximum level as well.
Below is an alphabetized list of all water systems in Illinois currently marked as containing forever chemicals above the advised maximum concentration level:
- Albany
- Belvidere
- Bloomington
- Cary
- Collinsville
- Crest Hill
- Criswell Court Mobile Home Park
- East Alton
- Family Manufactured Home Community LLC
- Fox Lake
- Freeport
- Galesburg
- IL American-Lincoln
- IL American – Peoria
- Lake In The Hills
- Moline
- Mount Vernon Association Inc.
- Nauvoo
- North Park PWD
- Pleasant Valley Public Water District
- Rainbow Lane Mobile Home Park
- Rockdale
- Rock Island
- South Elgin
- Sugar Grove

The synthetic compounds known collectively as PFAS are contaminating drinking water to varying extents in large cities and small towns — and in private wells and public systems, the U.S. Geological Survey said in July.
Some of the sample sites where the USGS found PFAS above 65 PPT were located in or near Ocala, Florida; Lake Carmel, New York; Mashpee, New York; Hastings, Minnesota; Woodbury, Minnesota; Ramsey, Minnesota; Isabel, South Dakota; Boulder, Colorado; and Galena, Alaska.
Sample sites in the 12-65 PPT range were found in and around Grass Valley, California; Fresno, California; Los Angeles; Lakewood, Colorado; Oak Park, Illinois; Chicago; Keswick, Michigan; Boger City, North Carolina; Philadelphia and more.
The USGS said most PFAS exposure was found near urban areas and potential chemical sources, with higher counts in the following regions: Great Plains, Great Lakes, Eastern Seaboard and Central/Southern/California.
What are PFAS?
PFAS is an umbrella term for thousands of chemicals that are used to make nonstick pans, food packaging, fire-fighting foams, to-go boxes, furniture, rugs, clothing and more. The chemicals are so ubiquitous it would be nearly impossible for most Americans to rid their home of them.
The chemicals are both extremely common and potentially dangerous.
Described as “forever chemicals” because they don’t degrade naturally in the environment, PFAS have been linked to a variety of health problems, including liver and immune-system damage and some cancers.
Studies of lab animals have found potential links between PFAS chemicals and some cancers, including kidney and testicular, plus issues such as high blood pressure and low birth weight.
The U.S. Environmental Protection Agency in March proposed the first federal drinking water limits on six forms of PFAS, or per- and polyfluorinated substances, which remain in the human body for years and don’t degrade in the environment. A final decision is expected later this year or in 2024.
