PUBLISHED: | UPDATED:

Something as simple as drinking tap water is exposing millions of Illinoisans to toxic chemicals that build up in human blood, cause cancer and other diseases and take years to leave the body.

Scientists call the chemicals per- and polyfluoroalkyl substances or PFAS. They are commonly known as forever chemicals because they don’t break down in the environment.

Despite plenty of warning signs, the Illinois Environmental Protection Agency didn’t begin testing the state’s water utilities for PFAS until August 2020. Then state and local officials downplayed the results, burying notices filled with technical jargon on government websites.

Until now the scope of PFAS problems in Illinois remained unknown. More than 8 million people in the state — 6 out of every 10 Illinoisans — get their drinking water from a utility where at least one forever chemical has been detected, according to a Chicago Tribune investigation that included a computerized analysis of test results and a review of court documents, government records and scientific studies.

Tracy Lehr, who has lived at the Criswell Court mobile home park in Joliet for 21 years, said she drinks and cooks with bottled water because the park's well is unreliable. Lehr said she wasn't informed that 2021 testing of the well water found toxic PFAS chemicals at levels up to 1,800 times higher than the U.S. Environmental Protection Agency's latest health advisory.

“It’s disgusting and overwhelming at the same time,” said Ellen Meeks Rendulich, co-director of a grassroots environmental group in Will County, where the state found PFAS in a dozen communities, including the Criswell Court mobile home park in Joliet.

Tracy Lehr remembered that state officials came twice last year to test a well on the property. Lehr, who has lived in Criswell Court for 21 years, said she and her neighbors were never warned their water is contaminated with PFAS at levels up to 1,800 times higher than the latest federal health advisory.

“I’ve never trusted the water here,” Lehr said as she pointed to shrink-wrapped packs of bottled water stacked throughout her trailer.

Part 2: Sewage sludge contaminated with toxic forever chemicals has been spread on thousands of acres of Chicago-area farmland

Sludge from the Metropolitan Water Reclamation District is dumped and spread on farms field in Will County on June 15, 2022.

Farmers on the edges of suburbia are encouraged to spread sludge on their fields by local officials, farm bureaus, university extension agents — even the U.S. Environmental Protection Agency.

But despite assurances the practice is safe and legal, sewage sludge is contaminating thousands of acres of northeast Illinois farmland with toxic forever chemicals, a Chicago Tribune investigation has found.

Farmer Ray Dettmering checks on a sprayer outside his home in Peotone on July 22, 2022. Dettmering said he didn't know about toxic forever chemicals prior to a conversation with the Tribune.

During the past six years, federal records show, more than 615,000 tons of sludge from the Metropolitan Water Reclamation District of Greater Chicago has been plowed into 29,000 acres near the nation’s third largest city. (All of that land combined is roughly the size of west suburban Aurora.)

Only the Greater Los Angeles area distributed more sludge to farmers during the period.

Meanwhile, researchers have concluded there is ample evidence that PFAS end up in crops and livestock.

Researchers and public health advocates are increasingly concerned because some PFAS build up in human blood, take years to leave the body and don’t break down in the environment. Others transform over time into more hazardous compounds, increasing the risk that grains, beans, hay and produce grown in sludge-amended soil could be tainted for years to come.

Part 3: Chicago’s sewage district fails to warn gardeners free sludge contains toxic forever chemicals

Mary Weaver picks tomatoes in her garden at a community garden in Evanston. Weaver and her fellow gardeners began using MWRD compost three years ago, drawn by the district's offer of free soil amendments to replace store-bought products.

Bags of the earthy muck are labeled organic or natural. Sometimes it is billed as exceptional quality compost. Industry held a nationwide contest years ago and decided to call it biosolids, a euphemism that beat out black gold, geoslime and humanure.

No matter how it is described, the humus-like material distributed to gardeners, neighborhood groups and landscapers by the Metropolitan Water Reclamation District is still sewage sludge — a byproduct of human excrement and industrial waste from Chicago and the Cook County suburbs.

How to reduce your exposure to PFAS

The state EPA is testing the water for toxic chemicals known as per- and polyfluoroalkyl substances (PFAS). Known mostly for their use in Teflon and Scotchgard products, PFAS are long-lasting and linked to cancer and other health problems and currently unregulated. (Erin Hooley/Chicago Tribune)

Long-term exposure to tiny concentrations of certain PFAS can trigger testicular and kidney cancer, birth defects, liver damage, impaired fertility, immune system disorders, high cholesterol and obesity, studies have found. Links to breast cancer and other diseases are suspected.

Forever chemicals found in drinking water throughout Illinois: Search the database

Water is pumped from the Harrison-Dever water intake crib in Lake Michigan through a tunnel that runs underneath the lake to the James W. Jardine Water Purification Plant. Worrisome concentrations of PFAS have been found in Chicago, which provides treated Lake Michigan water to more than 5 million people in the city and suburbs.

The Tribune identified 1,654 potential sources of PFAS statewide through a national analysis of industry codes that designate the type of products manufactured or used at a particular factory. Only California, Virginia, Pennsylvania and Florida have more facilities on the list of suspected polluters.

Physicians should test millions of Americans for toxic forever chemicals, the nation’s leading scientific advisory body urges in a new report that reflects growing concerns about unregulated compounds added to clothing, food packaging and household products.

New guidelines for the nation’s doctors came the same week another group of researchers estimated that exposure to forever chemicals — also known as per- and polyfluoroalkyl substances or PFAS — could cost the current U.S. population nearly $63 billion in hidden health costs.

The chemicals have been added to nonstick cookware, water-repellent clothing, stain-resistant fabrics and carpets, cosmetics, firefighting foams, food packaging and other products that resist grease, oil and water.

PFAS persist in the environment and accumulate in people, animals and aquatic life. These “forever chemicals” are in the blood of nearly every American, including newborn babies.
