New Jersey has state-specific regulations for Maximum Contaminant Levels (MCLs) in drinking water.
- PFOA: 14 parts per trillion (ppt)
- PFOS: 13 ppt
New Jersey adopts and incorporates by reference the National Primary Drinking Water Regulations, including maximum contaminant levels unless otherwise provided in the subchapter. The state has set specific PFAS MCLs for PFOA and PFOS.
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.
