What levels of PFCs found in drinking water are safe to drink?
USEPA has issued a lifetime drinking water Health Advisory for PFOA and PFOS of 70 parts per trillion (ppt)or (ng/L) either individually or when concentrations of PFOA and PFOS are combined. A Health Advisory identifies the concentration of a contaminant in drinking water at which adverse health effects are not anticipated to occur.
The New Jersey Department of Environmental Protection (NJDEP) developed a guideline for chronic (lifetime) exposures to PFOA of 40 ppt (ng/L). NJDEP has also established an interim specific ground water criterion for PFNA of 10 ppt (ng/L).

What are perfluoroalkyls?
Perfluoroalkyls are stable, synthetic chemicals. Perfluoroalkyls are unique because they repel oil, grease, and water. The two perfluoroalkyls made in the largest amounts in the U.S. are perflurooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS).
How can PFCs be removed from water?
Filters containing activated carbon or reverse osmosis units have been shown to be effective at removing PFCs from water supplies where they have been used and tested.
MDH has conducted a study of point of use water treatment devices – for more information see the information sheet entitled, "MDH Evaluation of Point-of-Use Water Treatment Devices for Perfluorochemical Removal Final Report - Summary" (PDF: 205KB/6 pages).
Other types of common water treatment systems, such as water softeners, are not likely to remove PFCs. Boiling the water will not remove the PFCs.
If you are interested in installing a water treatment system of any sort, be sure to work with a reputable supplier and check references.

Important update from Tracy Carluccio at Delaware Riverkeeper Network: Some of you got an email in August from me about the NJDEP proposed safe drinking water standard, also called a Maximum Contaminant Level (MCL) being proposed for PFNA. The comment period is open on this through 5pm on October 6. This is a reminder of the due date, or if you are just hearing about this, a request that you consider submitting a comment to NJDEP in support of the adoption by the state of a mandatory safe drinking water standard or MCL for PFNA.
As you may know, the NJ Drinking Water Quality Institute finished their studies and recommended a MCL of 13ppt 2 years ago. NJ is finalizing this by proposing to make a rule that sets a MCL for PFNA for all of New Jersey. This standard is more strict than what is being used as guidance now. So this will require all drinking water systems in NJ to be regularly tested for PFNA and water that is found to be contaminated with PFNA at 13ppt or greater has to be treated so it’s removed to below that level.
My organization, Delaware Riverkeeper Network, engaged an independent toxicologist when the Institute did their study and we are recommending an even stricter standard of between 3 and 5 ppt. Activated carbon treatment, which some your municipalities now have, removes PFNA to non-detect if it is operated properly. Some municipalities are “blending” water (diluting contaminated water by adding water with no or less PFNA) to keep the concentration of PFNA down. But currently there is no mandatory requirement to do this – the adoption of a MCL will make removal of PFNA to below the adopted MCL standard a requirement for all water suppliers. Water suppliers will have to report to consumers what the sampling of the water shows.
There is also a MCL being proposed for 1,2,3-TCP, which has been found in Burlington County – now all water systems in NJ will have to be tested for that chemical too and have it removed.
Information on these MCLs and other aspects of the proposed changes to the state’s Safe Drinking Water Standards can be found at DRN’s action alert where there is a link to all relevant information and some talking points for people to use to make comment. Here is the link: http://www.delawareriverkeeper.org/node/4977
For convenience, here is the link to the NJDEP rulemaking: http://www.nj.gov/dep/rules/notices/20170807b.html
The comment period for this rule is open to October 6, 5:00 pm. If you can make a comment supporting that DEP adopt a MCL, that will be most helpful. How to do that is explained in our action alert. The more support shown for the adoption of a MCL, the better, so please share this information with others. It is very powerful for the regulators to hear comments from people who have been exposed to contaminated drinking water – you are the impacted community members and have special influence because of what you have been – and in some cases – are still going through. So, your comment really matters. The Talking Points we provide on our action alert will help you write a letter but expressing your own thoughts and saying you have been exposed and want this toxic chemical regulated and removed from your water is the most important thing.

EAST GREENWICH TWP. — The township has voluntarily shut down one of its three public drinking wells after tests showed small amounts of Perfluoronananoic Acid (PFNA), an unregulated chemical that has caused at least two other municipalities to also shut down wells.
PFNA is a chemical in the family of Perfluorinated Chemicals (PFCs). While both state and federal environmental agencies have yet to set regulations for the chemical, the New Jersey Department of Environmental Protection recently set a draft interim standard for PFNA in drinking water of .20 parts per trillion.
East Greenwich’s three wells were tested in November and Well No. 3, which is located in the Mount Royal section of the township, was found to have PFNA at levels of .22 parts per trillion.
“We immediately shut down Well Three to protect the residents of our town,” said Deputy Mayor James Philbin.
Contaminated wells in West Deptford and Woodbury have been shut down for the same reason within the past few months.
A Paulsboro well that has been found to have the highest levels of PFNA found in the United States is still running as the borough’s other two wells are shut down for another, more dangerous contaminant.
Unregulated and untested on humans thus far, the effects of ingesting PFNA, which bioaccumulates in the body, are not known. However, in adult rodents, PFNA has caused problems such as decreased body weight, toxicity to the liver, kidney, immune system and male reproductive system, according to a DEP summary.
“That well was voluntarily shut down and will not run until parameters are given to us from the NJDEP,” said Mayor Dale Archer.
The East Greenwich Township committee also passed a resolution at its work session meeting on Thursday urging the DEP to create regulations for PFNA.
