- PFAS Monitoring: Approximately 189 New York public water systems serving over 1.3 million people have detected PFAS between 4-10 parts per trillion that will require action under new federal limits, while about 250 systems have exceeded the state’s PFOA and PFOS drinking water standards of 10 parts per trillion.
- Infrastructure Investment: Over $450 million in federal funding through the Bipartisan Infrastructure Law has been allocated to New York for water infrastructure improvements, including $35.6 million specifically for emerging contaminants and $274.6 million for clean water projects.
Major Water Sources and Challenges
- New York City System: The largest unfiltered water system in the US serves 8.3 million customers from upstate reservoirs, with minimal PFAS contamination but ongoing monitoring of the Croton System where trace levels have been detected below state limits.
- Long Island Aquifers: Heavily impacted by legacy contamination including PFAS from industrial sources and airports, requiring extensive treatment and monitoring programs to protect groundwater supplies for millions of residents.
- Aging Infrastructure: With some distribution systems over 100 years old, New York faces a $44.2 billion need for drinking water infrastructure improvements over the next 20 years, far exceeding current funding levels.
Emerging Contaminant Response
- PFAS Regulation Implementation: New EPA drinking water standards for PFOA and PFOS (4 parts per trillion) are expected to take effect in 2031 following EPA’s proposed extension, requiring over $1 billion in treatment technology investments from affected water systems across the state. EPA has announced plans to rescind standards for four additional PFAS compounds and reconsider their regulatory determinations.
- State Leadership: New York was among the first states to establish drinking water standards for PFOA and PFOS (10 ppt) in 2020 and for 1,4-dioxane (1 ppb), providing a framework for other states to follow.
- Comprehensive Monitoring: Public water systems must monitor for over 100 contaminants including PFAS, with requirements to report all detected levels and implement treatment when standards are exceeded.
Rural and Disadvantaged Communities
- Infrastructure Disparities: Small and medium-sized communities face challenges accessing state funding, with only 18% of $4 billion appropriated since 2015 reaching communities due to complex application processes and upfront costs.
- Targeted Federal Support: The Bipartisan Infrastructure Law mandates that majority funding goes to disadvantaged communities through grants and forgivable loans, with enhanced technical assistance programs to navigate regulatory requirements.
- Private Well Concerns: Approximately 2 million New Yorkers rely on private wells that are not federally regulated, leaving many residents without knowledge of PFAS or other contaminant levels in their drinking water.
Looking Forward: 2025-2030
New York’s water quality landscape is undergoing significant transformation as utilities prepare for new federal PFAS regulations taking effect in 2031. The state’s early adoption of PFAS standards and comprehensive monitoring programs positions New York as a leader in addressing emerging water quality challenges. However, successful implementation will require sustained investment exceeding $44 billion over 20 years to modernize aging infrastructure while ensuring all New Yorkers have access to safe, affordable drinking water. The state’s commitment to a $500 million clean water funding commitment as part of Governor Hochul’s 2025 State of the State, bringing total investment to a record $6 billion, demonstrates continued prioritization of water quality protection and infrastructure resilience.
Recommendations for New York Residents

Know Your Water Source
Contact your water utility to request annual water quality reports and ask about PFAS testing results. Visit the New York State Department of Health’s website to access your local system’s testing data and understand any contaminants of concern in your area.
