The Health Risks of PFAS in New York City Water

What are PFAS and Why Should New Yorkers be Concerned?

PFAS, short for per- and polyfluoroalkyl substances, are man-made chemicals used in many products. They provide anti-stick, stain-resistant, and water-resistant properties. PFOA and PFOS, part of this group, have been linked to health issues, posing a significant threat to New Yorkers. As awareness of these harmful effects grows, many individuals and businesses in New York are seeking solutions to mitigate the risks associated with PFAS exposure. One crucial step is to utilize pfas testing services, which help identify the presence of these chemicals in water and soil. By understanding the extent of contamination, communities can take proactive measures to protect public health and the environment.

Exposure to PFAS can cause various health problems. These include reproductive harm, immune system issues, higher cholesterol levels, thyroid and liver disease, and kidney and testicular cancer.

The environmental presence of PFAS is alarming. An estimated 98% of Americans have detectable PFAS levels in their blood. In New York State, about 50% of public water systems show PFAS contamination. Around 250 systems exceed the state’s drinking water standards for PFOA and PFOS.

Long Island is severely affected by PFAS contamination. About 2 million New Yorkers rely on private wells that may be contaminated. The EPA’s new drinking water standards will likely double the number of affected water systems in New York. This will require over a billion dollars to upgrade public water systems with necessary treatment.

As New Yorkers become more aware of PFAS health risks, it’s essential to act. We must address PFAS sources throughout their life cycle and enforce stricter regulations. This includes limiting their use in everyday products to protect public health.

PFAS in New York City Water: Current Levels and Compliance with Federal Standards

New York City’s drinking water, serving nearly 10 million residents, meets the new EPA standards for PFAS. The city’s Department of Environmental Protection (DEP) tests the water extensively. They analyze it hundreds of times daily, every day of the year, to ensure its safety and compliance with enforceable limits.

The water supply comes from a vast watershed over 125 miles long. It includes 19 reservoirs and three controlled lakes. While PFAS was found in the smaller Croton System in 2021 and 2024, the contamination levels were below state and federal limits.

DEP Commissioner Rohit Aggarwala’s Statement on PFAS Levels

DEP Commissioner Rohit Aggarwala believes protecting New Yorkers under these new standards won’t require big changes. New York State has been ahead in tackling PFAS. It set an MCL of 10 parts per trillion (ppt) for PFOA and PFOS in 2020. The state is also working to set standards for up to 23 PFAS compounds.

Comparing NYC’s Water to Other Contaminated Systems Across the Country

Unlike New York City, thousands of drinking water systems across the U.S. face contamination issues. For instance, Michigan tested 162 municipalities in 2018. They found six with PFAS contamination levels above ambient levels.

The new federal MCLs for PFOA and PFOS will be 4 ppt by 2029. This means public water systems will have to upgrade their infrastructure to meet these enforceable limits. New York City’s commitment to water quality testing and compliance ensures it can keep providing safe drinking water.

The Source of New York City’s PFAS-Safe Water

New York City’s drinking water, serving over 9 million residents, is celebrated for its quality and safety. It comes from a vast network of upstate reservoirs, mainly in the Hudson Valley and Catskill Mountains. These areas, known for their natural beauty and ecological importance, are key to providing clean, PFAS-safe water to the city’s inhabitants.

The Vast Network of Upstate Reservoirs

The New York City water supply system spans 19 reservoirs and three controlled lakes, covering 2,000 square miles. The Catskill/Delaware watershed, which supplies about 90% of the city’s water, is 125 miles north. It includes six reservoirs: Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie. The Croton watershed, just 40 miles north, supplies the remaining 10% and has 12 reservoirs and three controlled lakes.

Sampling Test Results from the Department of Environmental Protection

The New York City Department of Environmental Protection (DEP) conducts rigorous sampling tests to ensure the safety and quality of the city’s drinking water. Recent tests have shown that levels for 29 PFAS chemicals, including PFOA and PFOS, are below detection limits. This indicates the city’s water supply is in excellent condition regarding PFAS contamination.

The DEP’s proactive monitoring and maintenance of the city’s water supply, along with the pristine conditions of the upstate watersheds, ensure New Yorkers enjoy PFAS-safe drinking water. As the nation faces growing concerns over PFAS contamination, New York City stands as a model for effective water management and protection.

Steps Being Taken by DEP to Identify Potentia PFAS Sources

The Department of Environmental Protection (DEP) is actively working to identify sources of PFAS contamination in New York City’s drinking water. The U.S. Environmental Protection Agency (EPA) has set stricter regulations for PFAS, including legally enforceable Maximum Contaminant Levels (MCLs). The DEP is committed to ensuring compliance and safeguarding public health.

To aid in the source identification process, the DEP is collaborating with consulting firms that specialize in environmental risk assessment. These firms will conduct detailed investigations, focusing on the Kensico Reservoir and Kensico Basin. These areas are critical water sources for the city. The DEP aims to identify the origins of PFAS contamination and develop specific remediation strategies with the help of experts.

The EPA’s new regulations require public water systems to complete initial monitoring for six PFAS compounds by 2027. They must also reduce levels to meet the new MCLs by 2029. The DEP’s proactive efforts show its dedication to meeting these deadlines and ensuring the safety of New York City’s drinking water.

Once sources are identified, the DEP will work with the EPA and other agencies to implement effective remediation strategies. These strategies may include:

• Upgrading water treatment facilities with advanced filtration systems
• Collaborating with upstream communities and industries to reduce PFAS discharges
• Implementing best management practices to minimize further contamination

The DEP’s efforts aim to protect the health of millions of New Yorkers who depend on the city’s water supply. As awareness of PFAS risks grows, New York City stands as a model for proactive measures and collaboration in protecting public health.

Focusing on Kensico Reservoir and Kensico Basin

The Kensico Reservoir in Westchester County is a vital water source for New York City, serving over 8 million residents. The Department of Environmental Protection (DEP) is concentrating on the Kensico Reservoir and Kensico Basin to find pfas sources. This effort is part of the city’s commitment to ensuring safe drinking water.

PFAS Detection in Streams Within the Kensico Basin

Recent studies have found PFAS in some Kensico Basin streams, sparking concerns about water quality. Though NYC water PFAS levels are generally safe, the DEP is monitoring closely. They aim to address any contamination promptly.

Westchester County Airport as a Possible Source

The Westchester County Airport, within the Kensico Basin, is seen as a possible airport contamination source. It’s part of the state’s Brownfield Cleanup Program, showing the need for cleanup. This site is a focus for the DEP’s efforts to identify PFAS sources.

PFAS levels in the Kensico Basin are highest near the airport. The DEP is intensifying its search for sources in this area. Ensuring the Kensico Reservoir’s water quality is critical, as all unfiltered water from the Catskill and Delaware systems flow through it.

The DEP is looking for consulting firms to assess PFAS sources in the watershed. They’re focusing on the Kensico Reservoir and Kensico Basin. Through monitoring, advanced filtration, and investigations, they aim to keep NYC’s drinking water safe and of high quality.

How People are Exposed to PFAS and Associated Health Risks

PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals introduced in the 1940s. They are found in various products and industries. Exposure occurs through contaminated food, water, and consumer products.

In Orange County, New York, a 2020 study by the CDC and ATSDR found high PFHxS levels in blood. This was three times the national average. The City of Newburgh had to switch its water source in 2016 to lower PFAS levels. Though current water meets EPA standards, past exposure’s long-term effects are a concern.

Food contamination is another major exposure route. PFAS can enter the food chain, contaminating various products. The Orange County study showed higher PFUnA levels in those eating locally grown produce, highlighting food as a risk factor.

Exposure to PFAS is linked to several health issues. These include increased cholesterol, liver enzyme changes, and decreased vaccine response in children. It also causes behavioral and developmental problems in kids, high blood pressure in pregnant women, and small birth weight decreases. There’s also a risk of certain cancers and reduced immunity.

• Increased cholesterol levels
• Changes in liver enzymes
• Decreased vaccine response in children
• Behavioral and developmental issues in children
• Increased risk of high blood pressure or preeclampsia in pregnant women
• Small decreases in infant birth weights
• Increased risk of certain cancers, such as prostate, kidney, and testicular cancers
• Reduced immunity to fight infections
• Reproductive harms, including decreased fertility

The long half-lives of PFAS compounds mean they persist in the body and environment. This leads to ongoing health effects even after exposure reduction. Continued research and monitoring are essential to fully grasp PFAS-related health risks and protect public health.

The Prevalence of PFAS in Tap Water Across the United States

A recent study by the United States Geological Survey (USGS) has uncovered the alarming extent of PFAS contamination in tap water nationwide. The 2023 study analyzed 1,238 groundwater samples. It found that nearly half of the tap water across the country contained at least one type of PFAS chemical at detectable levels.

The USGS study focused on 24 common types of PFAS out of the over 12,000 known compounds. The most frequently detected PFAS included:

• Perfluorobutane sulfonate (PFBS)
• Perfluorooctane sulfonate (PFOS)
• Perfluorooctanoate (PFOA)

The study also developed a predictive model to identify areas with a higher likelihood of PFAS contamination. Yet, it does not provide specific city estimates or PFAS concentrations.

In Massachusetts, the study found that 86 to 98% of people using public water supplies could be exposed to PFAS. In Connecticut, 67 to 87% of those using private wells may face PFAS contamination.

This widespread contamination highlights the urgent need for strict regulations and proactive measures. It’s essential to protect public health from the risks associated with PFAS exposure.

EPA’s Expectations for Water Systems to Remove Regulated PFAS

The Environmental Protection Agency (EPA) is intensifying its efforts to tackle the growing issue of per- and polyfluoroalkyl substances (PFAS) in drinking water. This move could require thousands of water systems across the United States to implement treatment upgrades. The goal is to meet new compliance requirements and uphold water quality standards. The EPA’s strategy involves issuing test orders, finalizing significant new use rules, and eliminating exemptions for PFAS on the Toxics Release Inventory (TRI).

Under the Fifth Unregulated Contaminant Monitoring Rule (UCMR 5), public water systems serving 3,300 to 10,000+ people, as well as 800 randomly selected systems serving fewer than 3,300 people, are required to participate in nationwide monitoring for 29 PFAS compounds from January 2023 through December 2025. This monitoring will provide critical data to inform future regulatory actions and ensure the protection of public health.

New York City’s Advantageous Position

New York City stands out as it faces fewer challenges in meeting the new EPA requirements. The city’s high-quality water source and the Department of Environmental Protection’s proactive approach to identifying contamination sources have kept PFAS levels below the EPA’s maximum contaminant levels (MCLs). The MCLs for PFOA and PFOS are set at 4.0 parts per trillion (ppt).

As the nation tightens its grip on regulating PFAS in drinking water, New York City is committed to delivering safe, clean water. The city is dedicated to ensuring full compliance with state and federal water quality standards. By proactively addressing contamination risks and investing in treatment upgrades, New York City is well-prepared to meet EPA’s compliance requirements and safeguard public health.

The Need for New York Legislature to Address Upstream Sources of PFAS Contamination

PFAS chemicals are widespread, and environmental advocates are pushing for the New York Legislature to take action. They want to limit the use and production of these substances. With 98% of the U.S. population showing PFAS in their blood, the need for action is urgent.

PFAS, known as "forever chemicals," are found in many products and water sources. In New York, 19 communities face water pollution from toxic landfills. About 368,000 people rely on the Hudson and Mohawk rivers for drinking water. Each year, 89 million gallons of toxic waste contaminate these rivers.

The Ubiquitous Nature of PFAS Chemicals

The EPA has found around 120,000 facilities that may have handled PFAS. By August 2024, 2,067 sites reported PFAS in drinking water. The U.S. Geological Survey says at least 45% of tap water contains these harmful chemicals. PFAS contamination is found in all 50 states.

Health Effects Linked to PFAS Exposure

Studies show PFAS exposure can lead to serious health issues. These include increased cancer risk, hormone disruption, and liver problems. Birth defects, infertility, and weakened immunity are also linked to PFAS. Communities of color are disproportionately affected, highlighting environmental justice concerns.

Several states are taking steps to regulate PFAS. Connecticut banned PFAS in biosolids and wastewater sludge. Maine prohibits land application of biosolids. Michigan, Colorado, Vermont, New Hampshire, Minnesota, Massachusetts, and others require monitoring and reporting of PFAS. New York has also banned PFAS in clothing and other, following California’s lead.

The EPA is working on a National Primary Drinking Water Regulation for PFAS. Designating PFOA and PFOS as hazardous substances under CERCLA is also underway. It’s critical for the New York Legislature to implement chemical bans and strict regulations. This will protect public health and ensure a safer future for all.

PFAS Contamination in New York’s Public Water Systems

Per- and polyfluoroalkyl substances (PFAS) pose a significant threat to public water systems in New York State. Studies indicate that up to 50% of the state’s public water systems have detected PFAS contamination. Long Island is among the most affected areas, raising concerns about the safety of drinking water for many New Yorkers, including those using private wells.

It’s predicted that up to 94% of New Yorkers getting their water from public sources may be exposed to PFAS. This alarming figure emphasizes the need for immediate action to address PFAS contamination in public water systems. An estimated 56% of those using private wells are also likely to have PFAS in their water.

The Impact on Long Island and Private Well Users

Long Island has been severely impacted by PFAS contamination. A survey found that 83% of voters consider the quality of Long Island’s drinking water a "serious" problem. This widespread concern highlights the urgency for action to ensure access to safe drinking water.

Approximately 2 million New Yorkers relying on private wells for drinking water are uncertain about their water’s quality. Without regular testing, they may unknowingly consume PFAS-contaminated water, risking their health.

Estimated Costs for Public Water Systems to Meet Federal MCLs

The EPA’s stricter drinking water standards will likely double the number of water systems in New York with dangerous PFAS levels. Meeting these new maximum contaminant levels (MCLs) will require significant investment from public water systems across the state.

Public water systems will need to invest over a billion dollars in treatment costs and infrastructure upgrades to comply with the new federal MCLs. They will also face millions of dollars in annual operating and maintenance costs to keep their PFAS treatment systems effective.

Upstream Sources of PFAS Throughout the Production, Use, and Disposal Life Cycle

PFAS, a family of over 10,000 synthetic chemicals, have been in use for decades. Initially introduced in the 1940s, today, a few hundred are marketed for commercial use. Their widespread application has contaminated drinking water sources through various pathways. These include industrial discharges, air emissions, landfill leachate, and contaminated sludge.

Industrial discharges into water systems are a significant source of PFAS contamination. Exposure to certain PFAS, like PFOA and PFOS, has been linked to health issues. This has led to their ban or phase-out in many countries. The European Union is exploring a ban on PFAS, with exceptions for applications without substitutes.

Air emissions from PFAS production and use deposit these chemicals into water and soils. This further contaminates the environment. Landfill disposal or incineration of PFAS-laden products also contributes to contamination. Contaminated sewage sludge on agricultural lands is another pathway for PFAS to contaminate drinking water sources.

The persistence of PFAS in the environment is due to their strong C–F bond. This leads to long-term stability and bioaccumulation. PFAS exposure has been found in 97% of U.S. citizens tested. It has been linked to various health issues, including:

• Endocrine disruption
• Increased cholesterol
• Higher risk of certain cancers
• Thyroid disorders
• Reduced birth weights
• Lower vaccine response
• Cardiovascular disease

As regulations tighten and awareness grows, PFAS producers and manufacturers face increased costs. They also risk lost revenues. Providers of waste management, water treatment, and environmental testing are seeing a surge in demand. This is for upgrades and new technologies to address PFAS destruction.

The Importance of Limiting Further PFAS Contamination

New York City faces a critical challenge with PFAS in its water. The EPA’s new rule aims to cut PFAS exposure for 100 million people. This move could prevent thousands of deaths and illnesses, making immediate action essential.

To tackle this issue, New York must adopt an essential-use approach. This means stopping non-essential uses of PFAS upstream. By identifying where PFAS is not critical and safer alternatives exist, the state can reduce water contamination significantly.

Stopping Non-Essential Uses of PFAS Upstream

Many companies have already started phasing out PFAS in their products. This shows that product reformulation and using safer substitutes is possible. Examples include:

• Cookware
• Dental floss
• Paint
• Cleaning products
• Textiles
• Rugs
• Ski waxes
• Children’s products

Examples of Safer, Cost-Effective Alternatives

Choosing safer, cost-effective alternatives to PFAS is key. Companies can reduce contamination while keeping product quality high. This move not only safeguards public health but also shows corporate commitment to the environment.

"The EPA’s allocation of $1 billion to states and territories for PFAS testing and treatment at public water systems is a significant step forward in addressing the contamination crisis. This funding, as part of a $9 billion investment from the 2021 Bipartisan Infrastructure Law, will provide much-needed support to communities impacted by PFAS contamination."

New York City must ensure compliance with state and federal standards for PFAS. The state legislature needs to address PFAS contamination sources upstream. By focusing on essential uses and safer substitutes, New York can protect its residents from PFAS harm.

Proposed Legislation to Ban PFAS in Various Products in New York

New York is on the verge of a significant move to safeguard its people and environment from PFAS chemicals. The proposed legislation seeks to ban PFAS in a broad spectrum of consumer products. This includes personal care items, cosmetics, and menstrual products.

Assemblymember Zebrowski and Senator Hoylman-Sigal have introduced bills (A.3556C / S.5648C) to ban PFAS in everyday household items. Concurrently, Assemblymember Glick and Senator Webb (A.6969 / S.4265) aim to restrict PFAS in cosmetics. Assemblymember Rosenthal and Senator Fernandez (A.5990 / S.3529) focus on removing PFAS from menstrual products.

The necessity for these PFAS bans is highlighted by the state’s widespread contamination. Over 3,400 public water systems in New York have tested positive for PFAS. About 250 of these systems have levels of PFOA and PFOS exceeding state limits. PFAS contamination is also prevalent in more than 400 inactive landfills, mainly in rural areas where well water is the primary source.

Exposure to PFAS has been associated with several health risks. These include:

• Cancer
• Hormone disruption
• Liver and thyroid problems
• Interference with vaccine effectiveness
• Reproductive harm and abnormal fetal development
• Lower birth weights and altered puberty timing in adolescents
• High blood pressure during pregnancy, which can lead to serious childbirth effects

Research shows that BIPOC and femme-identifying women are more likely to be exposed to toxic products containing PFAS. As the cost of cleaning up PFAS in soil and water increases, Assemblywoman Deborah Glick stresses the importance of prevention over remediation.

By banning non-essential uses of PFAS in consumer products, personal care items, cosmetics, and menstrual products, New York can proactively protect its communities and the environment from the harmful effects of these persistent chemicals.

PFAS in New York City Water: Key Takeaways for Residents
