Newark – New Jersey – Water Quality Report 2025: PFAS Testing, Infrastructure Concerns & Safety across your city
Newark’s Department of Water and Sewer Utilities serves approximately 300,000 residents across Newark and sells water to surrounding communities including Belleville, Bloomfield, East Orange, Nutley, and South Orange. The utility manages over 500 miles of water mains, operates the Pequannock and Wanaque Water Treatment Plants, and delivers roughly 80 million gallons daily across this historic northeastern urban center.
Newark draws its drinking water from two primary sources: the Pequannock Watershed, a protected 35,000-acre forest reservoir system in northern New Jersey that has served the city since the 1890s, and the Wanaque Reservoir, operated by the North Jersey District Water Supply Commission. With average annual rainfall of approximately 47 inches, Newark benefits from reliable precipitation but faces the infrastructure challenges common to many older American cities. The city has undertaken unprecedented water system modernization since 2019, implementing a lead service line replacement program that successfully replaced over 23,000 lead service lines in under three years – one of the fastest such programs in American history. Newark’s transformation of its water system serves as a national model for addressing lead concerns through comprehensive community engagement, innovative financing, and efficient implementation in this densely populated urban environment.

Recommendations for Newark Residents
Request Water Testing
Newark residents can request free water quality testing by calling (973) 733-6303 or emailing waterandsewer@ci.newark.nj.us. Although most lead service lines have been replaced, testing is still recommended for homes built before 1986 with potential lead plumbing components, particularly given the recent discovery of incomplete replacements at some properties.
Consider Home Filtration
While Newark’s water meets all health standards, residents concerned about older interior plumbing or potential PFAS contamination may benefit from NSF-certified filters (Standard 53 for lead reduction and Standard 401 for PFAS reduction). Filters are particularly important in buildings where lead service line replacement is recent and system stabilization is ongoing.
Practice Conservation
Participate in Newark’s water conservation initiatives including free water-saving fixtures and leak detection assistance. Even in water-rich New Jersey, conservation helps reduce energy use, treatment costs, and utility bills while supporting sustainable water management.
Flush After Extended Absence
If your home has been vacant for more than six hours, run cold water for 3-5 minutes before using for drinking or cooking. This helps flush water that may have been in contact with plumbing materials and ensures you’re getting fresh water from the main line.
Report Water Issues
Report water main breaks, water quality concerns, or pressure problems immediately through the Newark Connect app or by calling (973) 733-3654. With ongoing infrastructure improvements, promptly reporting issues helps maintain system integrity and water quality.

Contaminants of Concern
Lead
Source: Previously from lead service lines (most now replaced), but may still be present in older interior plumbing components including fixtures, solder, and pipes in homes built before 1986. Recent contractor fraud case revealed some incomplete replacements that have since been remediated.
Health Effects: Developmental delays in children, reduced IQ, learning difficulties, kidney problems, cardiovascular effects in adults, particularly concerning for pregnant women and children under six
Current Status: Latest testing results show 0 ppb, well below the EPA action level of 15 ppb (reduced to 10 ppb effective 2027), following citywide lead service line replacement and optimized corrosion control treatment
Haloacetic Acids (HAA5)
Source: Formed when chlorine disinfectants react with naturally occurring organic matter in the water supply; levels can vary seasonally with changes in source water quality
Health Effects: Long-term exposure to elevated levels may increase risk of certain cancers and reproductive effects; short-term exposure is not considered an immediate health concern
Current Levels: Location-based quarterly monitoring shows HAA5 levels averaging 32 parts per billion in the Pequannock system and 38 parts per billion in the Wanaque system EPA Limit: 60 parts per billion as a locational running annual average
PFAS (Forever Chemicals)
Source: Per- and polyfluoroalkyl substances from industrial activities, firefighting foams, and consumer products that have contaminated groundwater sources including the Newark Basin aquifer system
Health Effects: Linked to increased risk of certain cancers, liver disease, thyroid disease, high cholesterol, decreased fertility, weakened immune system, and developmental effects in infants and children
Current Status: Newark water has tested positive for PFAS contamination. In 2023, Newark joined class-action lawsuits against companies responsible for PFAS contamination. EPA established maximum contaminant levels of 4 parts per trillion for PFOA and PFOS, with compliance required by 2027, though recent EPA policy changes may affect enforcement timelines.
Important Note on Recent Developments:
In October 2024, federal prosecutors charged JAS Group Enterprise Inc. and its executives with conspiracy to commit wire fraud for allegedly leaving lead pipes in place at approximately 1,500 Newark properties while falsely claiming completion and collecting over $10 million in payments. Newark has since conducted comprehensive audits and replaced any remaining lead components discovered during inspections. Residents can verify their service line status and request testing through the city’s water department.
Despite this setback, Newark’s overall lead service line replacement program remains a national model for rapid, comprehensive infrastructure improvement. The city continues to prioritize water quality monitoring and transparent reporting to maintain public trust and ensure safe drinking water for all residents.
