What are the PFAS standards in New Jersey?

Contaminant MCL (μg/L or ppb)* GWQS (μg/L or ppb)*
PFOA 0.014 0.014
PFOS 0.013 0.013
PFNA 0.013 0.013
*micrograms per liter or parts per billion

An MCL (Maximum Contaminant Level) is the highest allowable concentration of a contaminant in water delivered to a user of a public drinking water supply. MCLs apply to public water systems, including public community and public non-transient noncommunity water systems. Public community and public non-transient noncommunity water systems are required to routinely monitor for contaminants for which MCLs have been established and to take any action necessary to bring the water into compliance with an MCL.

The Ground Water Quality Standards (GWQS) establish classes of ground water according to the hydrogeologic characteristics of the ground water resource and the designated use(s) to be maintained, restored and enhanced within each classification area. Designated uses include maintenance of special ecological resources, provision of and conversion to potable water (drinking water), agricultural and industrial water supply, and other reasonable uses.

NJDEP has also established an Interim Specific Ground Water Quality Standard of 0.002 μg/L for ClPFPECAs.
