Water Quality in Massachusetts: What Homeowners Should Know
MWRA reservoirs, town wells, desalinated river water, private wells — Massachusetts drinks from all of them. Here’s what’s actually in your water, town by town, and what to do about it.

One State, Four Very Different Kinds of Water
Ask where Massachusetts tap water comes from and you’ll get four different answers depending on the town. Boston-area communities like Quincy and Milton drink MWRA water from the Quabbin and Wachusett reservoirs — naturally soft and closely monitored, but treated with chloramine and delivered through some of the oldest plumbing in America, where lead-era service lines still exist. Well-supplied towns like Mansfield, Franklin, and Needham pump hard groundwater that carries iron and manganese — the source of rust stains, metallic taste, and appliance-killing scale. Brockton blends reservoir water with desalinated water from the Taunton River. And thousands of homes on private wells are entirely responsible for their own testing. Layered over all of it: Massachusetts enforces one of the nation’s strictest PFAS standards (20 parts per trillion), and towns across the state have flagged detections. The common thread? What matters is what reaches your tap — and a free in-home water test answers that in 30 minutes.

How We Fix What the Test Finds
Whole-home Brita PRO systems that tackle hardness, chlorine, iron, and PFAS — better-tasting water from every tap and appliances that last years longer.
Engineered filtration for restaurants, offices, gyms, and facilities where water quality affects equipment, product, and customers every single day.
From dripping fixtures to full repipes and water heater swaps — licensed Massachusetts plumbers who quote upfront and clean up after themselves.
Furnaces, boilers, central AC, and cold-climate heat pumps — installed right the first time and maintained so they’re ready every season.
A quick, no-pressure test that shows exactly what’s in your water — hardness, chlorine, iron, pH — with results you can see on the spot.
Burst pipe, no heat, no hot water — a real person answers around the clock and emergency calls jump straight to the front of the line.
Matching the Fix to the Water
There is no one-size-fits-all filter. Hard well water wants a softener; iron and manganese want oxidizing filtration; chloramine taste and lead-era pipes want carbon and reverse osmosis at the tap; PFAS wants certified media. We test first, then match.

Where CleanTap Is Different
Most home service companies are built around a single trade, so every problem looks like that trade’s solution. We start from the house instead — how the water, the plumbing, and the heating and cooling systems affect one another — and recommend the fix that actually solves the problem, even when it’s the cheaper one.
Start With a Whole-Home Consult
In one visit we’ll test your water, look over your plumbing, and check the age and condition of your heating and cooling equipment. You get a plain-English rundown of what’s fine, what’s wearing, and what’s worth budgeting for — no scare tactics, no obligation.
Check Your Town's Water
We’ve written up the local water story for many of the communities we serve — see Norfolk County, Bristol County, Plymouth County, and Suffolk County, or jump straight to your town from our service area directory. Every public water system also publishes an annual Consumer Confidence Report; we’re happy to walk through yours with you during a free consultation.
Massachusetts Water Quality FAQs
Is Massachusetts tap water safe to drink?
Public supplies here are among the better-regulated in the country, and MWRA water in particular is excellent at the source. “Safe” and “ideal” aren’t the same thing, though — hardness, iron, manganese, chloramine taste, lead from older home plumbing, and PFAS all pass safety rules or arrive after treatment. A free in-home test shows what’s actually at your tap.
Do you really handle all three trades in-house?
Yes. Our filtration specialists, licensed plumbers, and HVAC technicians are all CleanTap — not subcontractors. They share notes on your home, which means faster diagnosis and no finger-pointing between trades.
What areas do you serve?
Greater Boston and Eastern Massachusetts — roughly everything east of Worcester — served from our Mansfield and Braintree locations. That includes Norfolk, Bristol, Plymouth, Suffolk, and Middlesex counties.
Are your technicians licensed and insured?
Every plumber and HVAC technician we send is licensed in Massachusetts, fully insured, and background-checked. We’re happy to share license numbers before work begins.
What are the most common water problems in Massachusetts?
By volume of calls we see: hard water and scale (well-supplied towns), iron and manganese staining, chlorine/chloramine taste (MWRA towns), aging-plumbing issues like lead solder in pre-1986 homes, and growing PFAS concern statewide. Each has a specific, proven fix — softening, oxidizing filtration, carbon, reverse osmosis, or certified PFAS media.
Can one visit cover more than one problem?
Absolutely — it’s one of the biggest reasons homeowners call us. The same appointment can cover a leaking valve, a water quality test, and a look at a struggling AC unit. One trip, one report, one plan.
How do I find out what's in my town's water?
Every public system publishes an annual Consumer Confidence Report (CCR) — search your town’s name plus “CCR” or check the town website. For what’s happening inside your own home’s plumbing, or if you’re on a private well, an in-home test is the only way. Ours is free and takes about 30 minutes.
Do you service equipment you didn’t install?
Yes. We repair and maintain all major brands of water heaters, filtration systems, furnaces, boilers, and AC equipment, regardless of who installed them.
Do you offer financing?
We do — flexible monthly payment options with $0-down plans on qualifying installations like filtration systems, water heaters, and HVAC equipment. Ask during your consult and we’ll walk you through the numbers.
How do I get started?
