Water resources meet new EPA guidelines

0

The Environmental Protection Agency’s updated drinking water health advisories for PFOA and PFOS were released on June 15.

The Greensboro Water Resources Department responded with a press release, including a video presentation from Water Resources Manager Mike Borchers answering common questions about the new guidelines.

In the video, Borchers said, “Is our water safe? Absolutely and categorically, yes, it is. We perform hundreds of thousands of water quality tests each year and they meet or exceed all state and federal regulatory limits and parameters for water quality. I support the water we provide to our customers every day. »

Borchers said, “The health advisory levels are guidelines” and notes that they are not enforceable or regulatory.

It also says that test results for PFOS and PFOA have been available online since 2018. Those results can be found here: www.greensboro-nc.gov/departments/water-resources .

Borchers says the EPA guidelines set in 2016 aimed for a combined level of PFOS and PFOA of 70 parts per trillion and that one part per trillion was equivalent to one drop in an Olympic-sized swimming pool.

New EPA guidelines for PFOA are 0.004 ppt and for PFOS 0.02 ppt.

Borchers says, “Our commitment is to use them as guidelines.

Borchers notes that the Department of Water Resources has been proactive in dealing with PFOA and PFOS and in 2015 initiated a watershed survey and assessment to determine the source of these emerging contaminants.

He said: “Currently we are pilot testing advanced treatment technologies in our Mitchell water treatment plan.”

Borchers said that once the best method of contaminant removal is determined, the Department of Water Resources will begin the engineering and design phases to upgrade the treatment plant “to remove these emerging contaminants at almost undetectable levels”.
