East Hampton homeowners near Cove Hollow Road have been seeing more news about PFAS contamination and private well testing linked to the 2023 fire at the battery storage facility on Cove Hollow Road. If you rely on a well, or you’re simply worried about what’s coming out of your taps, it can be hard to know what’s signal and what’s noise.
This guide walks through what’s publicly known about East Hampton PFAS water contamination around Cove Hollow, why local officials are testing wells, and how you can take practical steps to understand and improve your home’s water quality.
1. PFAS Impact and Responses Following the Cove Hollow Fire
The Town of East Hampton’s drinking water questions and answers (last updated October 15, 2026) summarize what the agencies involved have reported so far:
- PFAS in public supply wells: PFPrA, a type of PFAS, was detected in Suffolk County Water Authority (SCWA) wells at its Buckskill Road wellfield. SCWA took three of the four affected wells out of service and restricted the fourth to emergency use, and the Town says the water SCWA is delivering meets all drinking water standards.
- Likely source: The New York State Department of Environmental Conservation (NYSDEC) has determined that the likely source of the PFPrA is the facility’s use of the fire‑suppression agent Novec 1230, in combination with water, during the response to the 2023 battery storage fire.
- Private well testing: The Suffolk County Department of Health Services (SCDHS) has contacted households with private wells in the area being investigated and is testing those wells at no cost. According to SCDHS, private well sampling to date has found no contamination above New York State drinking water standards or the New York State Department of Health’s 3 ppb screening level for PFPrA.
1.1 What Investigators Have Found About the Source
PFAS concerns after a fire often center on firefighting foam or on the materials that burned. Here, the Town reports that firefighting foam (AFFF) was not used on the fire, and NYSDEC’s September 2026 Community Update points to the facility’s vapor‑based fire suppression system rather than the batteries: Novec 1230 combined with water can break down to PFPrA. SCDHS has also detected other PFAS, including PFOS, in groundwater in the area; the source of the PFOS has not been determined.
Because PFAS can be persistent in the environment, local agencies focus on well testing and longer-term monitoring after an incident like the Cove Hollow battery fire.
2. What PFAS and PFPrA Mean for Your East Hampton Water
The acronym PFAS refers to a broad class of man‑made chemicals. PFPrA (perfluoropropionic acid) is an ultra‑short‑chain member of that family. Unlike PFOA and PFOS, it has no specific drinking water standard; the New York State Department of Health is using a site‑specific screening level of 3 parts per billion to evaluate detections, and its health effects are still being studied. PFPrA is also not routinely sampled for: the Town notes that reliable laboratory analysis for it became available only recently.
2.1 Pathways for PFAS to Enter Private Wells
Some East Hampton homes depend on private wells rather than public water mains. That can matter in a situation like Cove Hollow, because:
- Public water systems can install centralized treatment and are subject to regular monitoring and reporting.
- Private wells are not covered by federal and state drinking water limits; homeowners are responsible for testing and treatment decisions.
When PFAS enter soil or surface water near a site, they can gradually move down into the underlying aquifer. Depending on local geology and groundwater flow, that plume may intersect with wells in the area over time. NYSDEC’s preliminary analysis, quoted by the Town, describes this kind of pathway: runoff containing PFPrA that drained from the building may have infiltrated the ground and flowed south over the past three years toward SCWA’s wellfield.
2.2 Why Relying on Your Neighbor’s Well Test Could Be Risky
One of the most confusing aspects of East Hampton PFAS issues is how site‑specific they can be:
- Two homes on the same road can show very different PFAS levels.
- A shallow well may experience different conditions than a deeper well drawing from another part of the aquifer.
- Groundwater flow can carry contaminants along narrow paths, skipping some homes and affecting others.
That’s why testing your own well is the only way to know what is present in it.
3. Steps to Determine If Your East Hampton Water Is at Risk
If you live near Cove Hollow Road or in another part of East Hampton where groundwater issues have been discussed, there is a straightforward sequence you can follow.
3.1 Consult Official Resources for Water Safety Information
- Review town Q&As: The Town of East Hampton has published drinking water questions and answers for residents, including a map of the area of concern, guidance for private well owners, and links to updates from NYSDEC, the State Department of Health, SCDHS and SCWA.
- Check for advisories or letters: Look for any mailings, door hangers, or public notices about the Cove Hollow area, PFAS testing, or recommendations to connect to public water.
- Understand your water source: Confirm whether your home is on:
- Public water (served by a water authority), or
- A private well on your property.
Public information and town updates are the baseline—but they still won’t tell you what’s happening inside your specific plumbing.
3.2 Arrange Targeted PFAS Testing for Your Well Water
If you have a private well inside the investigation area, SCDHS has been contacting households and testing those wells at no cost. Outside that area, testing is up to you; Suffolk County’s private well water testing guidance is a good place to start.
When you arrange testing, consider:
- Scope of analysis: Ask for a panel that includes PFAS compounds relevant to Long Island and East Hampton issues, along with basic water quality indicators (pH, hardness, metals, etc.). Standard PFAS panels may not include PFPrA, so ask the laboratory specifically whether it can test for it.
- Sampling locations:
- At a minimum, test at a kitchen tap where you draw drinking water.
- If you already have any filters installed, test both before and after the filter to see what’s in your raw well water vs. your household water.
- Frequency: After an incident like the Cove Hollow fire, some homeowners choose to retest periodically to see whether levels are stable or changing over time.
Measuring PFAS at the levels regulators use (parts per trillion and parts per billion) requires analysis by a certified laboratory; a free in-home water test is a starting point for understanding your water and your options. You can schedule one through the Free In-Home Water Test page.
4. Comparing Different Homeowner Responses: Wait and Watch, Bottled Water, or Filtration Installation
After hearing about East Hampton PFAS water contamination, many homeowners consider three main paths. Each has trade‑offs.
4.1 Comparative Overview of Water Safety Approaches
| Option | Short-Term Pros | Long-Term Considerations |
|---|---|---|
| Wait and Monitor Only | No upfront cost; you can watch for new town or SCWA updates | Does not address any PFAS or other contaminants that may already be in your well; may prolong uncertainty |
| Use Bottled Water for Drinking Only | Immediate change for drinking water; simple to start | Does not affect showers, baths, dishwashers, or laundry; recurring cost and plastic waste; lifting and storing bottles |
| Install Whole‑Home Filtration | Designed for every tap and fixture; addresses dependence on bottled water | Requires upfront investment and professional installation; you still need periodic system maintenance and monitoring |
Bottled water covers drinking and cooking only; it does not change the water used everywhere else in the house. A whole-home system is configured around what testing finds. For any specific contaminant, ask for independent certification data (for example NSF/ANSI listings) for the exact system you are considering.

Frequently Asked Questions
I live near Cove Hollow Road. Does public testing mean my well is safe?
SCDHS has contacted households with private wells in the area being investigated and is testing those wells at no cost. According to the Town’s Q&A, SCDHS reports that private well sampling to date has found no contamination above New York State drinking water standards or the State Department of Health’s 3 ppb screening level for PFPrA. However:
- Not every individual well is inside the investigation area.
- PFAS distribution can be uneven, depending on groundwater flow and well depth.
Federal and state drinking water limits do not apply to private wells, so testing is the owner’s responsibility. If your well has been tested by the county, follow the guidance county health officials give you based on your results; if it hasn’t, independent testing focused on your specific well is the most direct way to know what’s in your water.
My East Hampton home is on public water. Should I still consider filtration?
If you’re connected to a public water system, your water provider must meet federal and state drinking water limits, conduct regular monitoring, and publish an annual water quality report. In this case, SCWA took three of the four affected wells out of service and restricted the fourth to emergency use, and the Town reports that the water SCWA is delivering meets all drinking water standards.
Some homeowners on public water still choose whole‑home filtration to:
- Add an extra layer of treatment at the home level
- Address taste, odor, and sediment issues that can persist even with compliant tap water
- Address bottled water dependency for convenience and cost reasons
Whether that makes sense for you depends on your comfort level, water quality reports, and household priorities.
How often should I test my East Hampton private well for PFAS?
There is no single rule that fits every situation, but general practices in areas with known or suspected contamination often include:
- Baseline testing now, especially if you are near Cove Hollow Road or other sites mentioned in public contamination reports
- Follow‑up testing if:
- Town or county updates indicate changing conditions
- You install a new filtration system and want to document performance
- You notice changes in water quality (taste, color, or odor)
Whenever you test for PFAS, ask the laboratory whether its panel includes PFPrA.
