PARKERSBURG, W.VA. (WTAP) - Update: 3/04/2018
A Washington County water district says the chemical that replaced C8 has been found in testing of its water supplies.
But the results of other water systems vary.
Monday, the Little Hocking Water Association notified its customers of testing the U.S. EPA requested of water systems that installed filtration systems to remove C8 from their water.
This time, the testing involved GenX, the substance Chemours now uses to make non-stick products such as Teflon.
Little Hocking says GenX was detected in water that had not yet been treated in its activated carbon system.
Association Manager Jon Hanning went on to say in a news release the testing did not detect the chemical after it was treated.
But he added there are still scientific concerns about the effectiveness of carbon treatment at removing GenX.
Nearby, the city of Belpre installed carbon treatment systems-originally, to remove C8-at about the same time Little Hocking's system was being built.
Belpre Public Works Manager Michael Betz shared with us testing done in February by a firm hired by Chemours.
It showed levels mostly below the maximum safe limit for GenX and C8 in drinking water supplies.
Lubeck's Public Service District recently tests done of its system showed no signs of GenX.
Vienna Mayor Randy Rapp indicated the same, although he added he was informed of that verbally, and had not yet seen actual data.
Chemours has agreed to a federal agency's request to conduct water sampling for the chemical GenX, which the company began using as a replacement for the chemical C8.
In a letter to the United State Environmental Protection Agency dated Jan. 29, Chemours agreed to the agency's request to test four public drinking-water systems and 10 private wells.
"Chemours will sample the Chemours Washington Works raw and finished water in February 2018, when the routine monthly monitoring for perfluorooctanoic acid (PFOA) is conducted," the company says in its letter. "Chemours will mail letters to each of the remaining three public drinking water suppliers and the ten private drinking water supplies and present EPA’s request for the GenX sampling."
Chemours also asked the EPA for permission to do the sampling itself and said the company would conduct the GenX sampling "with its regularly scheduled biweekly, monthly, or quarterly sampling for PFOA, as appropriate."
Chemours says in the letter it will complete the GenX sampling during February. The EPA asked that the testing be done no later than March 31.
In its letter to Chemours dated Jan. 11, the EPA says carbon filters are in use at all of the water supplies in question.
GenX is manufactured at a Chemours plant in Fayetteville, N.C.
In its letter to Chemours, the EPA noted that GenX has been found in the Cape Fear River in North Carolina and in several water supplies downstream from that facility. The EPA also says GenX has been found in groundwater wells in the vicinity of the Fayetteville plant.
Chemours is currently providing bottled water to residential well owners in that area who water samples showed GenX levels above 140 parts per trillion.
The EPA says it's concerned that drinking-water wells "in the vicinity of the Washington Works facility may be similarly contaminated by GenX." The agency says GenX has been found in three on-site drinking-water wells at Washington Works.
The City of Vienna is the most recent water system to install equipment to filter out C8. That chemical was found to be in high concentrations in Vienna's water system, after the EPA changed its guidelines for the safe concentration of the chemical used by Chemours' predecessor, DuPont Washington Works, until 2015.
Mayor Randy Rapp said Wednesday he was told by Chemours that the filters, installed in 2016, could filter out GenX as well as C8.

The family of chemicals for whose effects attorneys are seeking studies includes the chosen substance to replace C8.
As we reported in August, those same attorneys are seeking answers about the use of GenX.
They include data on its release into the Ohio River, and what possible effects it has on human health.
Lubeck resident Joe Kiger, who was part of the original lawsuit regarding C8, is concerned about GenX's effects as well.
"That's what they call daimner acid salts-3, which falls into the PFOA category," Kiger says. "They've said 'all of this stuff isn't going to hurt you'. We've heard all that before. Yet, it carries all the family model and characteristics as PFOA, C8."
DuPont Washington Works, now part of Chemours, stopped production and use of C8 a few years ago.
That was after it sought permission from the West Virginia Department of Environmental Protection for the use of GenX.
Attorney Robert Bilott has now asked for a study on all perfllorinated chemicals or PFAS substances.
He pledges to file lawsuits if those studies have not begun.
Earlier this year, almost two decades of lawsuits and trials ended with a settlement, over the effects of the chemical C8.
But, just six months later, some are asking questions about the chemical that took its place.
Robert Bilott is a Cincinnati-based attorney who has represented people in various legal cases against DuPont, over its use of C8.
Bilott, according to a letter obtained by The News Center, has requested information from the West Virginia Division of Environmental Protection about the chemical that's replaced it, publicly called GenX.
Bilott's firm has questioned whether a consent order allowing the discharge of GenX into the Ohio River was granted before the effects of that chemical were fully determined.
It also asks whether DuPont, whose Washington Works plant is now owned by Chemours, began using GenX even before the DEP granted that consent order.
Bilott, in its request to the DEP, cites documents it received through public information requests as saying DuPont began using and discharging GenX by late 2011.
It further cites those documents as saying the consent order allowing that use and discharge was not formally signed until early 2012.
Bilott adds information it has obtained indicates DuPont later notified the DEP that some of the effects of GenX were similar to those found in its predecessor, C8.
Bilott has called on the DEP to ensure area drinking water is protected from any contamination from GenX.
We have reached out to the DEP and Chemours, via e-mail, for comment on Bilott's own questions.
When they respond to those requests, we'll let you know.
