Published Sept. 4 by the New Jersey Department of Environmental Protection (DEP) in the New Jersey Safe Drinking Water Act rules, New Jersey became the first state to set a maximum contaminant level (MCL) for perfluorononanoic acid (PFNA) in drinking water. New Jersey’s new standard for PFNA in drinking water is 13 ppt. However, municipalities will be given anywhere from six to eighteen months, depending on their size, to reduce their PFNA exposure to comply with the new standard.
PFNA is a man-made chemical that falls under a class of synthetic compounds called Per- and polyfluoroalkyl substances (PFAS). These are chemicals used in food production and packaging, textiles, and many other forms of manufacturing. Persistence of PFAS in the body and environment has been linked to adverse health effects in humans. Build-up of PFAS exposure may be related to high cholesterol, cancer, kidney disease, impaired immune function, pregnancy complications, and liver damage.
This ground-breaking act comes in response to an ongoing issue with PFNA contamination along the Delaware River. This contamination is largely resulting from previous releases of PFNA from a specialty polymer plant. Currently, 37 public New Jersey Water Systems fall above the new standard.
Additionally, in the new act, New Jersey has adopted a MCL for 1,2,3-trichloroproprane of 30 ppt. 1,2,3-trichloroproprane is another potentially harmful chemical that is released into the environment as a result of manufacturing practices.
