MWRA Water Supply

What's In Suffolk County's Tap Water?

Suffolk County's water comes from the Quabbin and Wachusett Reservoirs, treated by the MWRA. It's high-quality source water, but treatment chemicals and aging infrastructure introduce concerns at the tap.

Disinfection Byproduct

Disinfection Byproducts (TTHMs & HAAs)

Form when chlorine reacts with organic matter in reservoir water. Linked to bladder cancer and reproductive issues. MWRA monitors levels closely.

Status

Common in MA

Health Goal

Lowest possible

Heavy Metal

Lead (from service lines)

Not from MWRA source water — leaches from aging lead service lines and plumbing in pre-1986 homes. No safe level for children.

Status

Health Goal

0 ppb (any amount harmful)

PFAS

PFAS 'Forever Chemicals'

PFAS have been detected in water supplies across Massachusetts. These chemicals accumulate in the body and are linked to cancer, thyroid disease, and developmental issues.

Disinfectant

Chlorine & Chloramines

Required for disinfection but causes taste, odor, and dry skin. Reacts with organic matter to form byproducts.

Mineral

Hardness Minerals

MWRA water is relatively soft (1–4 grains per gallon) but can still cause minor scale buildup over time. Many older Suffolk County homes have galvanized plumbing that compounds mineral issues.

Common Suffolk County Water Problems

And the systems we use to solve them.

🧪

Disinfection Byproducts

Suffolk County's MWRA water is treated with chlorine and chloramines at the Carroll Water Treatment Plant. While safe for pathogen control, these disinfectants react with organic matter to form trihalomethanes (TTHMs) and haloacetic acids (HAAs).

Our solution

Whole-home carbon filtration removes chlorine and chloramines at the point of entry. An under-sink reverse osmosis system removes DBPs and other contaminants at the drinking water tap.

💧

Lead from Aging Infrastructure

Suffolk County has some of the oldest water infrastructure in the country. Many homes built before 1986 have lead service lines or lead solder in plumbing. MWRA water is lead-free at the source, but it can pick up lead as it travels through older pipes.

Our solution

A whole-home sediment and carbon pre-filter protects your plumbing, while an RO system at the kitchen sink removes lead and other heavy metals from drinking water.

☣️

PFAS "Forever Chemicals"

PFAS have been detected in water supplies across Massachusetts, including some communities served by the MWRA. These chemicals are used in firefighting foam, industrial processes, and consumer products. They do not break down in the environment or the human body.

Our solution

Reverse osmosis is the most effective residential technology for removing PFAS from drinking water. RO systems can reduce PFAS by 90% or more.

Water Quality in Suffolk County, MA — Common Questions

Does Suffolk County have hard water?

Suffolk County's water from the MWRA is relatively soft compared to many US cities, averaging 1–4 grains per gallon. However, many older Suffolk County homes and buildings have galvanized iron plumbing or cast iron pipes that can give water a metallic taste and contribute to mineral buildup. If you live in a pre-war building in Back Bay, Beacon Hill, or the South End, you may notice more scale on fixtures than the source water alone would suggest. A free in-home test tells you exactly what's happening at your taps.

Is Suffolk County tap water safe to drink?

Yes — Suffolk County's MWRA water consistently meets or exceeds all EPA Safe Drinking Water Act standards. The Quabbin and Wachusett Reservoirs are protected watersheds with excellent source water quality. However, "legal" and "optimal" are different. The water is treated with chlorine and chloramines for disinfection, which can create byproducts. More importantly, the last mile of delivery — your building's plumbing — is where lead and other contaminants can enter. For households with young children, pregnancy, or anyone concerned about long-term exposure, an under-sink reverse osmosis system removes 99%+ of contaminants including lead, PFAS, and disinfection byproducts.
