New Jersey – The Garden State – Water Quality Report 2025: PFAS Testing, Infrastructure Concerns & Safety across your state
New Jersey’s water infrastructure serves approximately 9.2 million residents across the nation’s most densely populated state, from the Hudson River corridor in the north to the Delaware Bay in the south. The state operates through a complex network of over 600 public water systems, ranging from large utilities like New Jersey American Water, which serves 2.7 million customers, to smaller municipal systems like Newark’s Water and Sewer Utilities serving over 400,000 residents. New Jersey’s water sources include the Delaware River, Raritan River system, and numerous reservoirs and groundwater aquifers that supply both urban centers and industrial facilities throughout the region.
Despite its reputation as the Garden State, New Jersey faces significant PFAS contamination challenges that rank among the most severe in the nation. According to the American Society of Civil Engineers’ 2025 Infrastructure Report Card, New Jersey’s drinking water infrastructure requires $8.6 billion in improvements over the next two decades. The state has received over $168 million in federal infrastructure investments from the Biden-Harris Administration’s Bipartisan Infrastructure Law to address these challenges, focusing on PFAS treatment, lead service line replacement, and emerging contaminant removal. New Jersey’s pioneering approach to PFAS regulation, being the first state to establish Maximum Contaminant Levels for these “forever chemicals,” demonstrates the state’s commitment to protecting public health through partnerships between the New Jersey Department of Environmental Protection (NJDEP), local utilities, and federal agencies.
New Jersey Water Quality: Current Status (2024-2025)
Statewide Compliance and Testing
- Overall Compliance: Most of New Jersey’s 600+ public water systems meet federal Safe Drinking Water Act standards, though the state faces the nation’s third-highest PFAS contamination levels, with PFAS detected in 63% of water systems serving 84% of the state’s population.
- PFAS Leadership: New Jersey became the first state to establish Maximum Contaminant Levels for PFAS chemicals, with comprehensive monitoring revealing some of the highest “forever chemical” concentrations nationally, particularly near industrial sites and military installations.
- Infrastructure Investment: Over $168 million in federal funding through the Bipartisan Infrastructure Law has been allocated to New Jersey for water infrastructure improvements, including dedicated funding specifically for PFAS treatment and lead service line replacement programs.
Major Water Sources and Challenges
- Delaware River System: Primary source for southern New Jersey communities, facing ongoing monitoring for industrial legacy contamination and requiring advanced treatment for emerging contaminants including PFAS.
- Raritan River Basin: Serves central New Jersey including key industrial areas, with documented PFAS contamination at facilities like the Raritan-Millstone Water Treatment Plant requiring ongoing pilot treatment programs.
- Regional Infrastructure Disparities: While major utilities like New Jersey American Water invest over $520 million annually in upgrades, smaller municipal systems face significant challenges meeting new federal PFAS regulations by 2031.
Emerging Contaminant Response
- PFAS Regulation Implementation: New EPA drinking water standards for PFOA and PFOS (4 parts per trillion) take effect in 2031, with New Jersey already having stricter state standards and comprehensive testing programs in place since 2019.
- Treatment Technology Deployment: Water utilities are implementing advanced treatment technologies including granular activated carbon and reverse osmosis systems, with facilities like Salem’s new PFAS removal system serving as models for statewide deployment.
- Historic Legal Settlement: New Jersey secured a landmark $450 million settlement with 3M in 2025 for statewide PFAS contamination, representing the largest such settlement in state history and providing funding for cleanup and prevention efforts.
Environmental Justice and Community Response
- Disproportionate Impact: Research shows communities of color and low-income areas in New Jersey face higher PFAS contamination levels, with 92% of Hispanic, 94% of Black, and 95% of Asian populations served by water systems where PFAS were detected.
- Federal Support: Dedicated funding streams through the Emerging Contaminant programs provide grants and forgivable loans to ensure equitable access to safe drinking water, with nearly 50% of infrastructure funds directed to disadvantaged communities.
- Lead Service Line Success: Cities like Newark have emerged as national models for lead service line replacement, having replaced over 23,000 lead pipes and demonstrating effective community engagement and rapid implementation strategies.
Looking Forward: 2025-2030
New Jersey’s water quality landscape continues to evolve as utilities prepare for the EPA’s 2031 PFAS compliance deadline. The state’s pioneering PFAS regulations and comprehensive monitoring programs position New Jersey as a national leader in addressing emerging water quality challenges. The historic $450 million settlement with 3M, combined with substantial federal infrastructure investments, provides unprecedented resources for system upgrades and community protection. However, successful implementation will require continued collaboration between state regulators, water utilities, and environmental justice advocates to ensure that all New Jerseyans have access to safe, affordable drinking water while addressing the complex legacy of industrial contamination that has historically challenged the Garden State’s water systems.
Recommendations for New Jersey Residents
Know Your Water Source
Contact your water utility to request annual water quality reports and ask about PFAS testing results. Visit NJDEP’s website to access your local system’s testing data and understand any contaminants of concern in your area, particularly PFAS levels.
Support Infrastructure Investment
Stay informed about local water infrastructure needs and support utility rate structures that enable necessary improvements. Attend public meetings when utilities discuss PFAS treatment upgrades and lead service line replacement projects.
Consider PFAS-Certified Filtration
For areas with known PFAS contamination above state limits, consider NSF-certified activated carbon or reverse osmosis filters specifically tested for PFAS removal. These can provide additional protection while utilities implement treatment upgrades.
Report Water Quality Concerns
Contact your local water utility immediately for taste, odor, or color concerns. Report suspected contamination to NJDEP’s Bureau of Safe Drinking Water at (609) 292-5550 for investigation and follow-up.
Practice Water Conservation
Support New Jersey’s water sustainability by implementing conservation measures like efficient irrigation, rainwater harvesting, and low-flow fixtures. Reducing demand helps utilities maintain system reliability and affordability during infrastructure transitions.
