Hawthorne Water System Update- PFAS

Perfluoronoanoic Acid (PFNA),  Perfluorotanoic Acid (PFOA) and Perfluorooctanesulfonic Acid (PFOS) are three chemicals within a larger class of chemicals known as Per- and polyfluoroalkyl substances (PFAS).   PFAS do not occur naturally, but are widespread and extremely persistent in the environment. They are man-made chemicals that have been used to make carpets, clothing, fabric for furniture, paper packaging for food, and other materials (such as non-stick cookware) that are resistant to water, grease or stains. They are also used for firefighting at airfields and in a number of industrial processes.

In 2016, the federal Environmental Protection Agency issued drinking water health advisory levels for PFOA and PFOS a maximum of 70 ppt either individually or combined. 


On September 4, 2018, New Jersey Department of Environmental Protection (NJDEP) promulgated regulations that set Perfluoronoanoic Acid (PFNA) Drinking Water Maximum Contaminant Level (MCL) at 13 parts per trillion (ppt).  The monitoring and testing for Hawthorne started the 1st Quarter of 2020.  All results from wells were non detected in 2020. 

The State of New Jersey did not regulate PFOA and PFOS until June 1, 2020, at which time the NJDEP established regulations setting Drinking Water MCL’s for PFOA at 14 ppt and PFOS at 13 ppt. Pursuant to these regulations, The monitoring and testing for Hawthorne (and other water utilities) started in 1st Quarter of 2021. Preliminary data shows that, although Hawthorne water is below the EPA advisory level of 70 ppt, we will exceed the NJDEP limits ofpr {FOA and PFOA, of 14 ppt and 13 ppt respectively.

Assuming our likely exceedance of the limits, Hawthorne authorized funding and is proactively designing a treatment system for PFOA/PFOS.  For more information, please watch the June 16, 2021 Council meeting and review the below power point presentation.  In addition, we are providing information on PFAS resources:
