New Jersey

New Jersey Department of Environment Protection (DEP)’s Division of Water Supply and Geoscience’s mission is to, “works to ensure New Jersey’s water supply is adequate, reliable, safe, and available for the future, based on sound science.” DWSG administers the SDWA as well as laws, regulations, and rules related to water quality and supply, wells, water allocation, management and finance, and drinking water standards. The Department of Health Drinking Water and Public Health Project “provides information to the public and works together with regulators to provide clean, safe drinking water to New Jersey residents” in collaboration with NJ DEP. New Jersey has over 600 community water systems which provide drinking water to approximately 87% of the State’s population. The State of New Jersey Board of Public Utilities has a Division of Water which regulates 32 water and wastewater utilities.  


Water Quality Accountability Act

Enacted 7/21/2017, went into effect 10/19/2017

The WQAA established new requirements for purveyors of public water to improve the safety, reliability, and administrative oversight of water infrastructure.  Asset management of infrastructure capital assets (pumps, motors, pipes, etc.) aims to minimize the total cost of owning and operating these assets in order to ensure planned maintenance can be done on time with adequate funding. All water purveyors who have an internet-connected control system must develop a Cybersecurity Plan.  


New Jersey Reg. 437, Ground Water Quality Standards and Maximum Contaminant Levels (MCLs) for Perfluorooctanoic Acid (PFOA) and Perfluorooctanesulfonic Acid (PFOS) Adopted Amendments: N.J.A.C. 7:1E Appendix A, 7:9C Appendix Table 1, 7:9E-2.1, 7:10-5.2, and 12.30; and 7:14A-4 Appendix A and 7.9

Adopted 3/31/2020

The Department adopted amendments to the New Jersey Safe Drinking Water Act (SDWA) rules (N.J.A.C. 7:10) to establish, as recommended by the New Jersey Drinking Water Quality Institute, a maximum contaminant level (MCL) for perfluorooctanoic acid (PFOA) of 0.014 micrograms per liter (µg/l) and an MCL for perfluorooctanesulfonic acid (PFOS) of 0.013 µg/l. The MCLs apply to public community and public noncommunity water systems. Public community and public noncommunity water systems are required to routinely monitor for contaminants for which MCLs have been established and to treat water when there is an exceedance of an MCL. The “Department is also adopting amendments to the Private Well Testing Act (PWTA) rules at N.J.A.C. 7:9E to require testing of private wells subject to sale or lease and to amend the SDWA rules to require testing of newly constructed wells for public noncommunity water systems and nonpublic water systems for PFNA, PFOA, and PFOS.” 




This law requires public water systems to provide written notice of elevated lead levels in drinking water to customers and local officials within ten days; requires landlords to notify tenants of elevated lead levels within three days of notice. Bills and Joint Resolutions were signed by the Governor in May 2021.
