ROME, Ga. — The consumption pumps that when drew 6 million gallons of water a day from the Oostanaula River now sit largely dormant on this northwestern Georgia metropolis.
Local officers contend that years of contamination miles upstream despatched poisonous perfluoroalkyl and polyfluoroalkyl substances, often known as PFAS, into Rome’s water provide, rendering it doubtlessly harmful for town’s roughly 37,000 residents. A water supply swap from the Oostanaula and added remedy have lowered the traces of the chemical compounds working by way of residents’ faucets, however they haven’t eradicated PFAS from the neighborhood’s water provide.
Test outcomes that discovered contamination in Rome have echoed in communities throughout the nation as researchers and regulators grapple with issues over the implications of consuming the ever present chemical compounds. Now, the Environmental Protection Agency is accelerating the controversy. In June, the EPA issued new advisories on PFAS in ingesting water that slash the extent that regulators think about protected for 4 chemical compounds within the household, together with two of the most typical, PFOA and PFOS.
The EPA well being advisories aren’t legally enforceable. But the company this 12 months is anticipated to suggest new limits on PFAS in public water techniques. If these ingesting water laws mirror the EPA’s newest advisories, water system operators nationwide will want to act to deal with the presence of these chemical compounds.
“It’s fairly an essential message,” stated Dr. Philippe Grandjean, a PFAS skilled and an adjunct environmental well being professor on the Harvard T.H. Chan School of Public Health. “This stuff is in every single place.’’
The Environmental Working Group, a analysis and advocacy group that tracks PFAS, stated it has logged greater than 2,800 websites within the U.S. which have PFAS contamination. Public information present the chemical compounds have turned up in water samples collected from dwelling water wells, church buildings, faculties, army bases, nursing properties, and municipal water provides in small cities like Rome and massive cities like Chicago.
They are also current in practically each American’s blood, in accordance to research. And some PFAS compounds bioaccumulate — that means that chemical concentrations aren’t simply cleared within the physique and as an alternative enhance over time as individuals devour hint quantities every day.
In July, a report from the National Academies of Sciences, Engineering, and Medicine stated PFAS testing ought to be supplied to individuals who have possible been uncovered to excessive ranges by way of their jobs or these dwelling in areas with recognized PFAS contamination. Grandjean, who helped overview the report for the National Academies, stated the committee concluded that “individuals have a proper to know their publicity degree and to be supplied correct well being care follow-up.” He stated that doing so is “essential and, in my thoughts, obligatory.”
Both the EPA advisories and the National Academies’ report comply with regular grassroots efforts to curb PFAS chemical compounds, which have been utilized in shopper merchandise for many years. Since their invention within the Nineteen Forties, the compounds — recognized by the moniker “perpetually chemical compounds” as a result of they don’t break down shortly — have been broadly utilized to family and industrial merchandise, together with carpet, waterproof garments, and nonstick cookware.
PFAS’ presence in firefighting foam, meals packaging, and even dental floss poses an ongoing problem. And efforts to cut back PFAS resemble the often-frustrating, decades-long marketing campaign to remove one other environmental hazard — lead — from properties, soil, and water.
“There has been a dramatic enhance in advocacy and public consciousness about PFAS,” stated Alissa Cordner, an skilled on the chemical compounds and an environmental sociology professor at Whitman College in Walla Walla, Washington.
In their report, researchers for the National Academies stated they discovered hyperlinks between publicity to PFAS and 4 well being situations: decreased immune response, elevated ldl cholesterol, decreased toddler and fetal development, and elevated threat of kidney most cancers. The report additionally discovered a potential affiliation between the chemical compounds and breast most cancers, adjustments in liver enzymes, elevated threat of testicular most cancers, and thyroid illness.
And EPA officers stated the company’s newest advisories are primarily based on new science and account for indications “that some unfavorable well being results could happen with concentrations of PFOA or PFOS in water which are close to zero.”
Most states don’t regulate PFAS, although.
That makes the EPA advisories essential, stated Jamie DeWitt, a professor of pharmacology and toxicology at East Carolina University. “The message from the EPA is that if these PFAS may be detected in ingesting water, they pose well being dangers,” she stated.
The American Chemistry Council, an trade commerce group, pushed again in opposition to the advisories and lately requested a federal courtroom to vacate them, saying that the company course of was “scientifically flawed and procedurally improper” and set “impossibly low requirements for PFOA and PFOS in ingesting water.” In a June assertion, the council stated PFAS have essential makes use of, together with in renewable vitality efforts and medical provides.
One producer of PFAS, 3M, stated in an announcement that the corporate “acted responsibly in reference to merchandise containing PFAS and can vigorously defend its document of environmental stewardship.”
The compounds’ improvement took off with preliminary hits in Teflon and later Scotchgard. There are 12,000 variations of them now, however solely about 150 are being studied by scientists and authorities companies, DeWitt stated.
U.S. producers voluntarily phased out PFOS and PFOA, the 2 most extensively produced, however they’re nonetheless present in ingesting water. The metropolis of Rome is amongst 10 North Georgia communities the place PFOS or PFOA have been present in ingesting water provides at larger ranges than the EPA advisories declare is protected, the state’s environmental regulatory company stated.
Six years in the past, officers in Rome have been pressured to swap town’s water provide from the Oostanaula to the close by Etowah River, a brownish tributary that merges with the Oostanaula close to a downtown bridge. Years of chemical contamination within the Oostanaula that Rome officers stated begins dozens of miles upstream in Dalton made the water doubtlessly harmful. They stated that in Dalton, the epicenter of U.S. carpet manufacturing, industrial waste containing PFAS has leached into the Conasauga River, which flows into the Oostanaula.

Officials in Rome plan to construct a $100 million reverse-osmosis filtering system to take away the chemical compounds from town’s water provide. Ratepayers will foot the invoice, though a lawsuit filed by town in opposition to carpet producers and their chemical suppliers goals to get better these prices. A separate lawsuit filed by a Rome resident and ratepayer levies related accusations in opposition to the upstream corporations. Defendants within the two Rome-based fits have denied the allegations.
The EPA introduced $1 billion in grant funding so states can deal with PFAS and different contaminants in ingesting water. But modifications to public water techniques nationwide will possible outstrip that allocation shortly.
Downstream from Rome, officers within the Alabama cities of Centre and Gadsden have reported excessive ranges of PFAS within the Coosa River and filed lawsuits in opposition to carpet makers. The Gadsden lawsuit is anticipated to go to trial in October.
The chemical compounds have drawn a flurry of litigation over the previous 20 years. A Bloomberg Law evaluation discovered greater than 6,400 PFAS-related lawsuits filed in federal courts between July 2005 and March 2022.
Substantial payouts have adopted. DuPont and Chemours, which made PFAS merchandise for many years, settled greater than 3,500 lawsuits in 2017 for greater than $670 million. Both corporations denied wrongdoing. And 3M settled a lawsuit from the state of Minnesota for $850 million. The identical firm settled litigation within the Decatur, Alabama, space for $98 million.
The EPA now ought to solid a broader internet to think about the wide range of the chemical compounds, Cordner stated. “The persistence of PFAS means we’ll be coping with this for a very long time,” she stated. “Because of their sheer amount, we’d like to deal with PFAS as a category. We can’t go chemical by chemical.”
EPA spokesperson Tim Carroll stated in an e-mail to KHN that the company is working to divide the massive class of PFAS into smaller classes primarily based on similarities equivalent to chemical construction, bodily and chemical properties, and toxicological properties. That work, he stated, would “speed up the effectiveness of laws, enforcement actions, and the instruments and applied sciences wanted to take away PFAS from air, land, and water.”
In the meantime, some corporations and the army have moved to cease utilizing the chemical compounds.
The Green Science Policy Institute, an environmental advocacy group, has developed an inventory of PFAS-free merchandise, together with rain gear and attire, footwear, child merchandise, cosmetics, and dental floss.
Two years in the past, Home Depot and Lowe’s stated they wouldn’t promote carpets or rugs with PFAS in them. This 12 months, the textile producer Milliken stated it could remove all PFAS from its amenities by the top of 2022.
A handful of flooring corporations have adopted go well with. Dalton-based Shaw Industries, a defendant within the Rome lawsuits, stated it has stopped utilizing PFAS in soil and stain therapies for residential and business carpet merchandise.
The Coosa River Basin Initiative, a Rome-based environmental advocacy group, has been monitoring the PFAS subject intently. Its government director, Jesse Demonbreun-Chapman, stated the EPA has moved “at lightning velocity’’ on PFAS, in contrast with different company actions.
But except the eventual laws are sweeping and the cleanups intensive, he stated, “we the individuals can be guinea pigs for PFAS-related well being issues.”
