Residents across Plainview, in the Town of Oyster Bay in central Nassau County, are hearing more about PFAS “forever chemicals” in the news and wondering what it means for their tap water. With New York State suing major chemical manufacturers over PFAS in Long Island drinking water, it’s natural to ask how much of this affects your own kitchen sink and shower. News 12 Long Island reports that New York’s Attorney General is suing several of the nation’s largest chemical manufacturers over PFAS contamination in drinking water across Long Island and the state.
This guide focuses on Nassau County PFAS water contamination, what’s known from public information, and the practical steps Plainview-area homeowners can take.
1. What Homeowners Need to Know About PFAS in Nassau County
1.1 What are PFAS?
PFAS (per- and polyfluoroalkyl substances) are a large family of man‑made chemicals used for decades in many everyday products. News 12’s report points to items such as cookware, children’s toys, dental floss and cosmetics.
Because PFAS break down very slowly, they can persist in the environment for years and have been documented in air, soil, and water. This is why they are often called “forever chemicals.”
According to News 12, people can be exposed to PFAS through:
- Drinking water: when groundwater or surface water is impacted
- Food: when it comes into contact with PFAS‑containing products, such as some cookware
- Inhalation: breathing air that contains PFAS
1.2 Why PFAS are a concern for Long Island drinking water
Long Island relies heavily on a sole‑source aquifer system for drinking water. When chemicals like PFAS reach groundwater, they can be difficult and expensive to manage.
According to News 12’s coverage of the New York State lawsuit, PFAS have contaminated drinking water supplies on Long Island and across the state. Because these chemicals persist for long periods, contamination can remain an issue even after the original source is controlled.
2. Linking New York’s PFAS Legal Actions to Local Water Supplies
2.1 What the lawsuit is about
The New York Attorney General is suing several major chemical manufacturers, accusing them of marketing and selling PFAS‑containing products that ended up contaminating drinking water supplies on Long Island and elsewhere.
An environmental advocate quoted in the News 12 report said the companies should be held accountable and hoped the lawsuit would force industry‑wide changes that reduce future contamination.
2.2 What lawsuits don’t change in your kitchen today
Legal actions and state‑level enforcement can:
- Push for cleanup funding
- Encourage stricter regulations
- Support upgrades to public water systems
However, they do not instantly change the water coming out of your tap in Plainview. Even as water providers implement treatment and monitoring, some homeowners look for additional layers of protection at the home level.

3. The PFAS Rules That Apply to Plainview’s Public Water
3.1 State and federal drinking-water limits
If your home is on public water, your supplier must meet state and federal drinking-water standards. New York set limits of 10 parts per trillion (ppt) for PFOA and PFOS and 1 part per billion (ppb) for 1,4‑dioxane in 2020, according to the New York State Department of Health. Until 2029, the state’s 10 ppt limits apply alongside the federal rule.
In April 2024, the U.S. Environmental Protection Agency (EPA) finalized limits of 4.0 ppt each for PFOA and PFOS, along with limits for PFHxS, PFNA, HFPO-DA (GenX) and certain PFAS mixtures. Public water systems must comply by 2029. In May 2026, EPA proposed letting systems request two more years (to 2031) for PFOA and PFOS and proposed rescinding the PFHxS, PFNA, GenX and mixture limits; those proposals were not final as of September 2026.
Your supplier’s annual water quality report (Consumer Confidence Report) lists the contaminants it detected, which is the best place to see how your own public water measures up.
3.2 Why Plainview homeowners still ask about home filtration
Even when public water providers are investing in treatment, some homeowners in Nassau County:
- Want more control over what happens at the point where water enters their home
- Prefer to add a whole‑home filtration system as a second line of defense
- Are looking to avoid long‑term bottled water purchases for everyday drinking and cooking

4. Understanding PFAS Alongside Other Emerging Contaminants in the Area
4.1 How 1,4‑dioxane fits into the picture
PFAS are not the only emerging contaminants that concern Long Island and Nassau County residents. 1,4‑dioxane is another, and New York was the first state to set a drinking-water limit for it, according to the New York State Department of Health.
1,4‑dioxane is also difficult to treat using conventional methods: the activated carbon that utilities widely use for PFOA and PFOS removes 1,4‑dioxane poorly, so utilities use advanced oxidation treatment for it.
While PFAS and 1,4‑dioxane are different chemicals, they share some characteristics that matter to homeowners:
- Man‑made origin and long‑term use in industry and consumer products
- Persistence in groundwater
- Need for specialized treatment technologies beyond basic disinfection
4.2 Why combined contaminant concerns drive interest in filtration
For some Plainview households, the concern is not just one chemical, but the overall picture of emerging contaminants in the region’s groundwater.
This can lead homeowners to:
- Ask for comprehensive water testing that looks at a range of potential contaminants
- Consider whole‑home systems that are configured based on local water conditions
- Re‑evaluate long‑term reliance on bottled water for daily use

5. Actionable Advice for Plainview Residents
You don’t need to be a water expert to take meaningful steps around PFAS and other contaminants. Here is a simple, sequential approach for Plainview homeowners.
5.1 Step 1: Review your current water source
- Identify your supply: Confirm whether you’re on a public water system or a private well. Public drinking-water limits don’t cover private wells; well owners are responsible for testing their own water.
- Check local reports: Public systems publish annual water quality reports that may mention PFAS or other emerging contaminants.
- Note any changes: Keep track of taste, odor, or appearance changes, even if they’re not directly linked to PFAS, as they can prompt broader testing.

5.2 Step 2: Decide whether to pursue testing
- Clarify your goals: Are you mainly concerned about PFAS, or do you want a broader contaminant profile?
- Gather existing data: Review any past test results, real estate inspection reports, or utility notices.
- Plan for follow‑up: Understand that testing is a snapshot; contaminants can vary over time, so you may want periodic checks.
Measuring PFAS and 1,4-dioxane 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.
5.3 Step 3: Evaluate your filtration options
Once you have a sense of your water quality, you can compare approaches:
- Point‑of‑use filters: For a single sink or fridge line, focused on drinking water
- Whole‑home systems: For comprehensive coverage across taps, showers, and appliances
- Combination setups: For example, a whole‑home system plus a dedicated drinking water filter at the kitchen sink
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.

6. Bottled Water vs. Whole-Home Filtration: A Side-by-Side View
Some families respond to PFAS headlines by stocking up on bottled water, but that approach has trade‑offs. Here’s a simplified comparison of common considerations:
| Factor | Heavy Bottled Water Use | Whole‑Home Filtration System |
|---|---|---|
| Coverage | Drinking only | Drinking, cooking, bathing, cleaning |
| Monthly out‑of-pocket | Ongoing bottle purchases | Occasional maintenance once system is installed |
| Convenience | Lifting, storing, and disposing | Water available from every tap |
| Plastic waste | High | Significantly reduced bottle use |
| Control over treatment | Dependent on bottling company | Configured to your home’s water conditions |
Some homeowners choose a filtration‑first strategy, keeping a small amount of bottled water on hand for emergencies while relying on filtered tap water for daily life.

Frequently Asked Questions
How do I know if PFAS is an issue for my Plainview home?
Public water suppliers publish annual water quality reports that list the contaminants they detected, which may include PFAS. If you’re on a private well, or if you want more specific data for your address, a targeted test by a certified laboratory is the most direct way to understand your situation. pHountain Water Filters can help you review the results and what they mean for filtration choices.
Are Plainview homes on public water safe from PFAS?
Public water suppliers must meet federal and state drinking-water limits, including New York’s 10 ppt limits for PFOA and PFOS, and must report what they detect in an annual water quality report. Reading your supplier’s latest report is the best way to see how your water measures up. Private wells are not covered by those limits; well owners are responsible for testing their own water. Each homeowner’s comfort level is different, and some choose to add home filtration for an extra layer of control.
Will a single pitcher or faucet filter handle PFAS and other contaminants?
It depends on the product. Some point‑of‑use filters are designed to target specific contaminants, but not all are designed for PFAS or a broad range of emerging contaminants. Before relying on any filter, whether at one tap or for the whole home, check its independent certification for the specific contaminant you’re concerned about.
How can I get started if I’m in Plainview?
The simplest first step is to request a water analysis and consultation. pHountain Water Filters will review your situation, discuss PFAS and other contaminants, and outline filtration options that fit your home and budget.
