Is Rhode Island’s Tap Water Safe? What Every Homeowner Should Know About PFAS and Water Quality

Most Rhode Islanders don’t think twice about the water coming out of their tap. You turn on the faucet, fill a glass, and trust that everything is fine. And for the most part, Rhode Island’s public water systems do meet federal safety standards.

But meeting the federal minimum and having the cleanest possible water in your home are two very different things. And over the past few years, a growing body of research — much of it happening right here in Rhode Island — has raised serious questions about contaminants that most standard testing wasn’t even looking for until recently.

If you’ve seen headlines about PFAS, “forever chemicals,” or lead in drinking water and wondered what it actually means for your family, this post breaks it down in plain language — and explains what you can do about it.

The professional Rhode Island plumbers from Martel Plumbing & Heating are here to help!

What Are PFAS and Why Should Rhode Islanders Care?

PFAS stands for per- and polyfluoroalkyl substances. They’re a group of man-made chemicals that have been used in everything from nonstick cookware and food packaging to firefighting foam and waterproof clothing since the 1940s. The reason they’ve earned the nickname “forever chemicals” is simple: they don’t break down. Once they enter the water supply, the soil, or your body, they stick around for a very long time.

Exposure to elevated levels of PFAS has been linked to a range of health concerns including increased cholesterol, thyroid problems, immune system effects, and increased risk of certain cancers. Children and pregnant women may be especially vulnerable.

This isn’t a distant problem. Rhode Island has documented PFAS contamination at multiple sites across the state. The former Quonset Naval Air Station in North Kingstown and the area around T.F. Green Airport in Cranston are both known contamination zones, largely from the use of PFAS-containing firefighting foam over many decades. In January 2026, a study led by researchers at the University of Rhode Island found that two old textile mill retention ponds along the Pawcatuck River in Bradford and Westerly are still actively releasing PFAS into the water — and one of those sites could continue doing so for over 100 years.

EPA testing data shows that most of the water systems with PFAS detections above safe limits in Rhode Island are concentrated in the northern part of the state — the same region where the majority of Martel’s customers live and work.

Rhode Island’s Response: Stricter Standards Than Most States

Rhode Island has actually been ahead of the curve on this issue. The Rhode Island PFAS in Drinking Water, Groundwater, and Surface Waters Act, passed in 2022 and amended in 2023, requires all public water systems in the state to regularly test for six specific PFAS chemicals. The law set an interim maximum contaminant level (MCL) of 20 parts per trillion — which is stricter than what many other states have in place.

If a water system’s PFAS levels exceed 70 parts per trillion, it’s required to issue a “do not drink” notice to customers. For levels between 20 and 70 parts per trillion, water systems have to take active steps to bring those numbers down.

These regulations are a positive step. But they apply to public water systems, not private wells. If your home is on well water — and thousands of Rhode Island homes are — you’re responsible for your own testing and treatment. The Rhode Island Department of Health operates a Private Well Program that can help you understand your options, but the testing and any necessary treatment are on you as the homeowner.

It’s Not Just PFAS: Lead and Aging Infrastructure

PFAS gets the headlines, but it’s far from the only concern in Rhode Island’s water. Lead contamination is another issue that hits close to home — literally.

Rhode Island has some of the oldest housing stock in the country. Many homes, particularly across Providence, Pawtucket, Cranston, and Central Falls, were built with lead service lines or lead solder in their plumbing. Even if your municipal water supply is clean at the source, lead can leach into your water as it travels through old pipes on its way to your faucet.

Beyond lead, common water quality issues in Rhode Island include hard water and mineral buildup, chlorine and disinfection byproducts from the treatment process, sediment and particulate matter in older systems, and elevated iron or manganese in well water. Each of these affects the taste, smell, and safety of your water — and each can be addressed with the right treatment system.

One other factor worth mentioning: Rhode Island’s low-lying coastal geography makes some groundwater sources vulnerable to saltwater intrusion, particularly during droughts and storm surges. Saltwater in the water supply doesn’t just taste bad — it can also accelerate corrosion in your home’s plumbing, which can lead to other contamination issues down the line.

How to Find Out What’s Actually in Your Water

Before you decide on any treatment system, the first step is understanding what’s actually in your water. There are a couple of ways to do this.

If your home is on a public water system, your water provider is required to publish an annual Consumer Confidence Report that details exactly what was found in testing. Providence Water, for example, makes their reports available on their website. You can request a copy from your provider or check the Rhode Island Department of Health’s public drinking water resources. The Environmental Working Group also maintains a free Tap Water Database where you can look up your specific water system and see which contaminants have been detected.

If your home is on a private well, the responsibility falls on you. Contact RIDOH’s Private Well Program to learn about testing recommendations and find certified labs in the area. At a minimum, well water should be tested for bacteria, nitrates, and lead. Given the current PFAS landscape in Rhode Island, adding PFAS testing to that list is a smart move.

Once you know what you’re dealing with, the right treatment solution becomes much clearer.

Water Treatment Solutions for Rhode Island Homes

At Martel Plumbing & Heating, we install a full range of water treatment systems designed to address the specific water quality challenges that Rhode Island homeowners face. Here’s a breakdown of the most common options and what each one does.

WHOLE-HOME WATER FILTRATION — A whole-home filtration system treats your water at the point of entry, meaning every faucet, showerhead, and appliance in your home gets filtered water. These systems are effective at reducing sediment, chlorine, and disinfection byproducts. They also protect your plumbing and appliances from buildup and corrosion. For most homes on municipal water, a whole-home carbon filtration system is a strong starting point.

REVERSE OSMOSIS — If your water has elevated levels of PFAS, lead, or other dissolved contaminants, a reverse osmosis (RO) system is one of the most effective treatment options available. RO systems push water through a semipermeable membrane that removes up to 99% of dissolved solids, heavy metals, fluoride, and PFAS. These are typically installed at a single point of use — like your kitchen sink — to provide the cleanest possible drinking and cooking water.

WATER SOFTENING — Hard water is common in Rhode Island, and the effects are easy to spot: mineral scale on fixtures, dry skin and hair, soap that doesn’t lather well, and shortened appliance lifespans. A water softener removes calcium, magnesium, and other minerals that cause hardness, protecting your plumbing and making daily life noticeably more comfortable.

UV WATER PURIFICATION — For homes on private well water where bacteria and microorganisms are a concern, UV purification uses ultraviolet light to neutralize harmful organisms without adding any chemicals to your water. It’s often used in combination with other filtration methods for comprehensive protection.

The right solution depends on your water source, what’s in it, and what your goals are. Some homes benefit from a single system. Others — especially older homes on well water — may need a combination approach. We’ll walk you through every option so you can make the best decision for your home and your budget.

Why Professional Installation Matters

It’s tempting to grab a water filter off the shelf and call it done. And for basic taste improvement, a pitcher filter or faucet attachment can help. But if you’re dealing with real contaminants — PFAS, lead, bacteria, or heavy metals — the stakes are higher than what a countertop filter is designed to handle.

Whole-home systems, reverse osmosis installations, and water softeners all need to be properly sized, plumbed, and configured for your home’s specific water pressure, pipe layout, and usage patterns. An improperly installed system can restrict flow, create pressure problems, or simply not filter effectively. It can also void the manufacturer’s warranty.
