Do I Still Need a Filter If My Medford or Bellport Home Is Being Connected to Public Water?

In May 2026, the Suffolk County Water Authority (SCWA) announced that it and Suffolk County had fully funded a water main extension near National Boulevard in Medford and Bellport to connect up to 20 homes, previously served by private wells, to public water after county well testing found significant levels of PFAS.

If you live in this area, you may be asking: once my home is connected, do I still need a home water filtration system?

This guide walks through what the project involves, where public water helps, and why some Long Island homeowners still choose whole-home filtration as a second layer of protection.

1. Overview of the May 2026 Medford–Bellport Water Main Extension

According to SCWA’s release of May 18, 2026:

1.1 Project specifics at a glance

• Location: the vicinity of National Boulevard in Medford and Bellport, in the Town of Brookhaven
• Issue: Suffolk County Department of Health Services testing of private wells in a PFAS assessment area found significant levels of PFAS, making the area a priority for public water
• Scope: 4,660 feet of water main, connecting up to 20 homes to the public water supply
• Funding: a $960,000 New York State grant plus about $1.1 million in American Rescue Plan Act funds from Suffolk County, together covering the full project cost
• Costs covered: the main, the lateral lines to the property line, and the private service lines to the homes; SCWA says residents will face no costs to connect

SCWA noted that without this funding, connecting would have cost property owners tens of thousands of dollars. The release gave no connection dates; officials toured the construction site at the time of the announcement to review the project’s progress.

Public water is overseen and tested under stricter rules than private wells. For many homeowners, this extension offers an important upgrade over relying on a contaminated well.

2. What PFAS Are and Why They Matter for Well Owners

PFAS (per- and polyfluoroalkyl substances) are a large family of synthetic chemicals that can persist in the environment.

Because Long Island draws its drinking water from groundwater, the only way to know whether a particular well is affected is laboratory testing. If you want a broader overview of how these chemicals show up across the region, pHountain Water Filters explains the bigger picture in Long Island Has a PFAS Problem. Here’s What You Need to Know.

3. Contrasting the Role of Public Water and Private Wells in This PFAS-Affected Area

Even in the same neighborhood, public water customers and private well owners face different situations, because different rules apply to each.

In April 2024, the U.S. Environmental Protection Agency (EPA) finalized enforceable limits of 4.0 parts per trillion (ppt) each for PFOA and PFOS in public water systems, 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.

New York set its own limits of 10 ppt for PFOA and PFOS for public water systems in 2020, according to the New York State Department of Health. None of these limits cover private wells: EPA notes that private well owners are responsible for the safety of their own drinking water.

3.1 Advantages offered by the new public water main

For homes that connect to the new main:

1. Source change: You move away from a PFAS-impacted private well to a regulated public supply.
2. More oversight: Public water providers must follow state drinking water standards and perform regular testing.
3. Central treatment: PFAS and other contaminants are typically addressed at the wellfield or treatment plant, not at each individual home.

For many residents, this substantially improves baseline water quality compared to staying on a known contaminated well.

3.2 Limitations of relying on public water without home filtration

Even with public water, there are reasons some homeowners add home filtration:

• Distribution system: Water can pick up sediment, metals, or byproducts as it travels through miles of mains and household plumbing.
• Household-specific plumbing: Older pipes, fixtures, or in-home plumbing materials can influence what comes out of your tap.
• Broader contaminant mix: PFAS is one concern; homeowners may also worry about chlorine, disinfection byproducts, heavy metals, or other industrial contaminants that can be present at low levels.

That’s why some families treat the public system as the first line of defense, then use whole-home filtration as a second layer tailored to their own house.

4. Evaluating the Need for Filtration After Your Home Connects to the New Main

The answer depends on your risk tolerance, plumbing, and long-term goals.

4.1 Why some homeowners rely solely on public water

• Regulatory confidence: You’re comfortable with state standards and local testing.
• Budget focus: You prefer to minimize new household expenses.
• Short-term stay: You expect to move within a few years and don’t want to invest in infrastructure.

For some households, connecting to the new main and stopping there feels like enough.

4.2 Reasons others supplement with a whole-home filtration system

Some Long Island homeowners who switch from wells to public water still choose whole-house filtration to:

• Standardize water quality at every tap: Not just the kitchen sink, but showers, bathrooms, laundry, and outdoor spigots.
• Address non-PFAS concerns: Such as chlorine taste and odor, sediment, or other environmental contaminants.
• Add a personal margin of safety: Even when public water meets standards, some families prefer an extra barrier between the supply and their taps.

5. Practical Guidance: Planning Your Next Moves on National Boulevard

For Medford and Bellport residents in and around the project area, a step-by-step approach can keep decisions manageable.

5.1 Step 1: Confirm your inclusion in the water main extension

1. Check eligibility: Confirm with SCWA whether your address is among the up to 20 homes in the extension area.
2. Understand timing: Ask SCWA when your home is expected to be connected.
3. Clarify costs: SCWA says connection costs are covered for homes in the project, including the private service line; confirm whether any plumbing work inside your home falls outside that.

5.2 Step 2: Review your current water quality status

Even if you’re scheduled to be connected:

• Well owners: Keep copies of any PFAS test results you already have.
• Public water customers nearby: Consider testing if you’ve noticed taste, odor, or staining issues, especially if your home has older plumbing.

If you’re on well water outside the project area, pHountain Water Filters has a dedicated guide: What Your Well Water Isn’t Telling You. The Suffolk County Department of Health Services also takes applications for private well testing.

5.3 Step 3: Determine whether to filter before or after connection

Some homeowners choose to:

• Install filtration now, especially if they’re uneasy using the well until the connection is made.
• Wait until after connection, then test again and decide based on the new water source.

There isn’t a single right answer — it depends on how you balance cost, timing, and peace of mind.

6. The Role of Whole-Home Filtration Systems for Medford and Bellport Homes

A whole-house system is not a replacement for the water main project — it’s a complement.

6.1 What a whole-house system does

A whole-house system treats water at the point where it enters the home, so the kitchen, bathrooms, laundry, and outdoor fixtures all receive the same filtered water.

The pHountain Filtration System is a whole-home (point-of-entry) system with a cartridge-free media design intended to reduce common impurities in tap water. It is installed directly into your plumbing by trained technicians and backed by a 10-year guarantee.

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.

6.2 Advantages of professional filtration system installation

• Correct sizing: Systems are matched to your home’s water usage and plumbing layout.
• Clean integration: Technicians ensure the system works smoothly with existing pipes and fixtures.
• Verification: After installation, the system is tested for proper operation, and homeowners are shown how everything works.

To learn more about how these systems are applied across the region, see Whole-Home Water Filtration for Suffolk County.

7. Comparing the Medford–Bellport Water Main Extension with Home Filtration Options

Here’s a simple comparison of what the public main extension and a whole-home filtration system each bring to the table.

Both approaches can work together: the public system manages water at the community level, and home filtration adds a customized layer at the household level.

If you’re in Medford or Bellport and want to understand your water before or after the main connection, you can request a Free In-Home Water Test from pHountain Water Filters.

8. How pHountain Water Filters Supports Long Island Homeowners Affected by PFAS

Whether you’re on a PFAS-impacted well, recently connected to the new main, or already on public water elsewhere in Suffolk County, the process is similar.

8.1 Standard consultation and service workflow

1. Initial outreach: You contact pHountain Water Filters through the Contact Us page.
2. Water evaluation: 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.
3. System recommendation: Based on results and household size, a customized filtration setup is recommended.
4. Professional installation: Technicians install the system into your home’s plumbing.
5. Follow-up and support: You receive guidance on maintenance and periodic check-ins as needed.

8.2 Importance of tailored filtration in the context of regional PFAS challenges

Across Long Island, PFAS is part of a larger water quality story. Infrastructure projects help, but they don’t always address every concern at the tap.

9. Common Questions from Medford and Bellport Homeowners About PFAS and Filtration

9.1 My home near National Boulevard is part of the water main project. Should I still test my water?

Yes. Even if you plan to connect, testing your current well gives you a baseline and helps you decide whether to:

• Use filtration while you wait for connection
• Continue filtering even after you’re on public water

After connection, you can test again to see how the new supply compares.

9.2 I’m on a private well near Medford–Bellport but not in the project area. What should I do?

If you’re outside the current extension area:

• Treat the project as a signal that PFAS has been found in local private wells: SCWA says county testing in the area found significant levels.
• Remember that public drinking-water limits don’t cover private wells, so testing is up to you; consider independent testing by a certified lab for PFAS and other contaminants.
• If results show issues, you can explore filtration and other options tailored to your home.

pHountain Water Filters serves homeowners across Suffolk County and broader Long Island; see Water Filtration Long Island NY for regional coverage details.

9.3 If I already invested in a whole-home system and then connect to the new main, is my system wasted?

No. A whole-house filtration system can stay in place after you switch water sources. The system can:

• Continue treating all water that enters the home after the source changes
• Keep house-wide coverage in place if the municipal supply changes in the future

In some cases, your installer may recommend minor adjustments based on the new water chemistry.

9.4 How does this Medford–Bellport project relate to PFAS issues elsewhere on Long Island?

The Medford–Bellport extension is one example of how local authorities are responding to PFAS findings in private wells. For a broader view, see Long Island Has a PFAS Problem. Here’s What You Need to Know and Levittown and the EPA PFAS Drinking Water Limits: What Homeowners Should Know.
