What Are PFAS?
Per- and polyfluoroalkyl substances, commonly called PFAS, are a large family of man-made chemicals developed for their water- and stain-resistant properties. They were used for decades in products like nonstick cookware, stain-resistant fabrics, food packaging, and firefighting foam. PFAS resist degradation in the environment and can persist for years in soil, water, and living tissue. That long persistence is why they are often called forever chemicals.
PFAS include many individual compounds. Some of the most frequently discussed are PFOA and PFOS, but newer variants such as GenX and PFBS have emerged as manufacturers shift to alternative chemistries. Long-chain PFAS behave differently than short-chain PFAS in water treatment and in the human body, so identifying which PFAS are present matters when choosing a response.
How PFAS Reach Home Water Supplies in New England
In New England, a mix of historical industrial activities and modern sources account for most PFAS detections in groundwater and surface water. Homeowners with private wells are uniquely vulnerable because well water is not subject to the same routine monitoring and treatment as public water systems.
Common Local Sources
- Firefighting foams used at airports, fire training facilities, and military sites
- Industrial sites that manufactured or used PFAS-containing products
- Landfills and wastewater treatment plants where PFAS-containing waste and biosolids accumulate
- Historic contamination from textile or leather processing facilities
- Urban runoff and long-range transport that deposit PFAS into watersheds
State agencies such as the New Hampshire Department of Environmental Services track known contamination sites and provide public maps and advisories. Southern Maine and Massachusetts maintain similar databases and community outreach programs. Local knowledge matters: a homeowner near an airport, a former military installation, or a landfill should prioritize testing and be vigilant about changes in water taste, smell, or color that could indicate other problems warranting immediate attention.
Exposure Pathways and Health Risks
People are exposed to PFAS through several routes, but drinking water is the most direct pathway into the body for many homeowners. Once ingested, certain PFAS accumulate in the bloodstream and organs and can persist for years. Scientific research links PFAS exposure to a range of health concerns, though strength of evidence varies by compound.
Health Outcomes Associated with PFAS
- Elevated cholesterol levels
- Immune system effects, including reduced vaccine response in children
- Increased risk of certain cancers, notably kidney and testicular cancer in some studies
- Thyroid dysfunction
- Developmental effects in fetuses and infants, such as reduced birth weight
- Liver enzyme changes and other metabolic impacts
Regulators and researchers typically describe PFAS risks as a matter of increased likelihood rather than immediate poisoning at low levels. Risk depends on many factors, including the specific PFAS compound, the concentration present, duration of exposure, age, and underlying health. Pregnant women, nursing mothers, and young children are often advised to be especially cautious.
How to Test for PFAS in Home Wells and Tap Water
Testing is the only way to know whether PFAS are present in a home water supply and at what concentrations. Homeowners should approach testing methodically to obtain reliable results that inform effective treatment choices.
Which Compounds to Test For
Many labs offer PFAS panels that include common compounds such as PFOA, PFOS, PFHxS, PFNA, PFBS, and GenX. A comprehensive panel gives a better picture because different PFAS respond differently to treatment and have different health implications.
Sampling Best Practices
- Use a certified laboratory experienced in PFAS analysis. PFAS tests require careful handling to avoid contamination from clothing, packaging, or sampling equipment.
- Collect samples in accordance with lab instructions. Labs usually supply pre-cleaned bottles and clear directions for sampling, shipping, and chain of custody.
- Test raw well water and treated tap water, if a treatment system is already installed, to check treatment effectiveness.
- Consider seasonal testing. Groundwater concentrations can change with seasons, rainfall, and nearby activities.
Costs vary with the scope of the panel and the lab, but homeowners should budget a few hundred dollars for a thorough PFAS panel. Local health departments sometimes offer subsidized testing programs for private wells; homeowners should check state resources. Contact A&B Water Consultants for a free PFAS removal services quote.
Interpreting Test Results
Interpreting PFAS results can be confusing because regulatory benchmarks differ across agencies and evolve over time. Federal, state, and local authorities may each issue different advisory levels or action limits. Homeowners should not rely on a single number without context.
Key points to consider when reviewing results:
- Which PFAS are detected. Long-chain compounds often bind more readily to treatment media than some short-chain alternatives.
- Combined concentration. Some health guidance focuses on the sum of several PFAS rather than individual compounds.
- Regulatory guidance. Compare results with state guidance from NHDES, Maine DEP, or the Massachusetts Department of Environmental Protection, and with federal resources available through the EPA.
If any PFAS are detected above guidance thresholds used by local agencies, homeowners should act promptly to reduce exposure and consult a qualified water treatment professional. Even when levels are below state advisories, households with infants, pregnant people, or those with specific health concerns may choose to install treatment as a precaution.
Treatment Technologies for Removing PFAS
Removing PFAS from drinking water is technically possible, but effectiveness varies by the compound, water chemistry, and system design. A & B Water Consultants draws on 25 years of experience in water treatment to recommend systems tailored to household needs in New Hampshire, southern Maine, and Massachusetts.
Point-of-Use vs Whole-House Systems
Point-of-use systems treat water at a single tap, typically the kitchen sink, where most ingestion happens. Whole-house systems treat all incoming water, which can be important for households concerned about PFAS in water used for cooking and bathing.
- Point-of-use (POU): Reverse osmosis systems are the most reliable POU option for removing a broad spectrum of PFAS. They are cost-effective for drinking and cooking water where treated volumes are modest.
- Whole-house: Granular activated carbon (GAC) or anion exchange systems can be configured to treat all household water. Whole-house systems are larger and more expensive but reduce dermal and incidental exposures throughout the home.
Common Technologies Explained
- Granular Activated Carbon (GAC): GAC absorbs many long-chain PFAS effectively. Media life depends on influent concentrations, flow rates, and competing contaminants. GAC systems require periodic media replacement or regeneration and careful system sizing.
- Anion Exchange Resins: These engineered resins can capture certain PFAS compounds that GAC may not remove as effectively. Resins are often used when PFAS concentrations are higher or for short-chain PFAS.
- Reverse Osmosis (RO): RO membrane systems can remove a wide range of PFAS at point of use. They are excellent for drinking and cooking water, but produce a waste stream that must be managed and typically do not handle very high production volumes without larger systems.
- High-Pressure Membranes and Nanofiltration: These are used in larger community systems and can be effective, but cost and complexity often put them beyond the scope of a private home.
- Advanced Oxidation: Not effective for PFAS removal. Oxidation can break down many organic contaminants, but does not reliably destroy PFAS because of their strong carbon-fluorine bonds.
Selection depends on the specific PFAS detected, water chemistry including iron and manganese content, and household needs. A poorly sized or maintained system can underperform and lead to false assurance, so professional design and commissioning matter.
Costs vary widely. A properly installed whole-house system that incorporates GAC or ion exchange can range from a few thousand dollars to over ten thousand dollars, depending on flow rate and complexity. Point-of-use RO systems typically start at several hundred dollars plus installation and ongoing filter replacement. Contact A&B Water Consultants for a free PFAS removal services quote.
Maintenance, Monitoring, and Certification
After installation, ongoing maintenance is critical. That includes scheduled media replacement, pressure monitoring, and periodic re-testing of treated water to verify performance. Independent certifications and third-party testing results are helpful when comparing products. Homeowners should request performance data on PFAS reduction and review the maintenance plan before purchase.

Practical Steps Homeowners Can Take Right Now
Homeowners do not need to wait for extensive regulatory guidance to take sensible actions. Practical steps that reduce exposure and build confidence include:
- Get water tested using a PFAS panel from a qualified lab.
- Use bottled water or an NSF-certified point-of-use RO system for infant formula, drinking, and cooking if PFAS are detected at concerning levels.
- Protect the wellhead and eliminate pathways for surface contamination to enter the well.
- Avoid using biosolids or compost made from sewage sludge on gardens if the source is unknown or known to be contaminated with PFAS.
- Keep informed through NHDES, Maine DEP, or MassDEP advisories and maps showing known contamination sites.
If a household receives a test showing elevated PFAS, it should act promptly and consult an experienced water treatment professional to design a mitigation plan tailored to the family’s needs. Contact A&B Water Consultants for a free PFAS removal services quote.
Costs, Funding, and Support Options
Treatment can be a significant investment. Homeowners should explore state programs, private grants, and community resources that can offset costs. A & B Water Consultants can advise on potential funding sources, documentation required, and whether replacement rather than retrofit would be more cost-effective over time.
Some practical financial considerations:
- Point-of-use solutions require lower upfront costs but may need more frequent filter changes.
- Whole-house systems have higher upfront costs and potentially higher maintenance, but they address a broader range of uses within the home.
- Insurance rarely covers contamination unless tied to a specific insured event; homeowners should review policies and consult agents where relevant.
Emerging Research and Regulation
Regulation and science on PFAS continue to evolve. Federal and state agencies are increasingly focused on setting enforceable limits and supporting remediation of contaminated community water supplies. Homeowners should expect more clarity and potentially stricter standards in the coming years as states refine action levels and the EPA finalizes national guidance.
Staying current requires periodic review of trusted sources: NHDES, Maine DEP, MassDEP, and the EPA. Working with experienced local consultants who track regulatory changes and emerging technologies helps families make timely, cost-effective decisions.
Case Example: A New Hampshire Family Finds PFAS in Their Well
A family in central New Hampshire had a private well serving a home with young children. Routine private testing revealed low but measurable levels of several PFAS. The family contacted a local water treatment firm for guidance. The consultant recommended immediate use of bottled water for infant formula while designing a two-part system: a point-of-use RO system for the kitchen tap and a whole-house GAC filter to reduce overall household exposure during bathing and cooking. After installation and follow-up testing, PFAS levels at the kitchen tap were below detection. The family enrolled in a service plan to monitor media life and schedule changeouts. This layered approach balanced immediate protection, long-term mitigation, and manageable costs.
Frequently Asked Questions
How quickly do PFAS tests return results?
It depends on the lab and the testing panel, but most certified labs return results within one to three weeks. Turnaround may be faster for prioritized samples. Homeowners should confirm expected timelines when arranging testing.
Can boiling water remove PFAS?
No. Boiling does not remove PFAS and may concentrate them slightly if water evaporates. For PFAS removal, physical treatments such as RO, GAC, or ion exchange are effective options depending on the compound.
Are short-chain PFAS less risky than long-chain PFAS?
Regulatory and health assessments show different behaviors. Short-chain PFAS often move more readily through groundwater and can be harder to remove with conventional GAC, but some have shorter biological half-lives. Risk depends on the specific compound, concentration, and exposure duration. A tailored testing and treatment plan is essential.
Should I replace my well if PFAS are detected?
Replacing a well is rarely the first recommended action. Treatment systems can provide effective, timely protection. Well replacement may be considered in extreme scenarios but does not address contamination in the broader aquifer. Consulting a qualified water professional helps evaluate options and costs.
Where can homeowners find reliable information about local PFAS risks?
State agencies are the best starting point. In New Hampshire, NHDES provides maps, advisories, and guidance. Maine DEP and MassDEP have similar resources. Local health departments and regional environmental groups can also help identify testing resources and community response plans.
Conclusion
PFAS present a complex challenge for homeowners who value the safety and health of their families. Because PFAS are persistent and can accumulate over time, testing and informed mitigation are the most effective means to reduce exposure. New Hampshire, southern Maine, and Massachusetts homeowners should prioritize testing, understand the specific PFAS present, and choose treatment systems designed for those compounds and their household needs.
