Where Does Lowell's Water Come From?
Water Source
Merrimack River (treated at city water treatment facility)
Lowell draws its drinking water from the Merrimack River, treating it at the city's water treatment facility. As a historic mill city, Lowell's water infrastructure dates back to the industrial revolution. The combination of aging pipes, river source water requiring extensive treatment, and dense older housing stock creates a complex water quality challenge for this Gateway City.
What's in Lowell's Water?
Based on water quality reports, testing data, and environmental assessments, these are the contaminants of concern for Lowell residents:
Lead
Status: HIGH RISK — Mill city infrastructure
Lowell's industrial history left a legacy of old infrastructure. The city has thousands of potential lead service lines, particularly in the dense neighborhoods surrounding the historic mill district. Homes built before 1950 are at highest risk.
HAA5 (Haloacetic Acids)
Status: Detected — River water treatment
Treating Merrimack River water requires significant chlorine disinfection, which creates HAA5 byproducts. River source water typically has more organic matter than reservoir water, leading to higher byproduct formation potential.
TTHM (Trihalomethanes)
Status: Detected — Seasonal fluctuations
Trihalomethanes accompany HAA5 as disinfection byproducts. Levels increase during summer when the Merrimack carries more organic material and water temperatures are higher.
PFAS ("Forever Chemicals")
Status: Detected from upstream sources
The Merrimack River receives discharge from upstream communities, including traces of PFAS. While treatment reduces levels, the river source means Lowell is exposed to whatever enters the waterway upstream.
Health Risks for Lowell Residents
According to the EPA and Environmental Working Group (EWG), prolonged exposure to contaminants found in Lowell's water may increase risk of:
- • Lead Exposure: Lowell's dense old housing means lead risk is pervasive. Children in older apartments are especially vulnerable
- • Cancer Risk: Long-term HAA5 and TTHM exposure from river water treatment increases cancer risk
- • Developmental Harm: Lead and PFAS both cause developmental problems in children, including reduced IQ and behavioral issues
📍 Lowell Local Tip
Lowell residents in the Acre, Centralville, and Back Central neighborhoods — your areas have the oldest housing stock in the city. Many of these apartments were built for mill workers in the 1800s and have never had their plumbing fully updated. If you're a renter, you might not know what pipes are behind your walls. An under-sink RO system costs less than a year of bottled water and provides better protection.
The Solution: Reverse Osmosis Filtration
Standard pitcher filters (like Brita) are not effective at removing Lead or most contaminants found in Lowell's water. Water quality experts recommend a Reverse Osmosis (RO) system that can remove up to 99% of dissolved contaminants.
Why RO Works for Lowell Water:
- ✓ Removes 99%+ of Lead, HAA5, TTHM
- ✓ Uses semi-permeable membrane to filter at molecular level
- ✓ Fits under your kitchen sink — no major renovation needed
- ✓ Provides clean drinking and cooking water on demand
- ✓ NSF-certified systems are independently tested and verified

Is Lowell MA water safe to drink?
Lowell water meets federal standards at the treatment plant, but aging infrastructure means lead is a significant risk at the tap. The Merrimack River source also requires heavy treatment, creating disinfection byproducts. Home filtration is recommended, especially in older homes.
Does Lowell have lead pipes?
Yes, Lowell has significant lead infrastructure from its industrial past. The city is conducting a lead service line inventory as required by the EPA. If you live in a home built before 1986, lead solder or service lines may be present.
Is the Merrimack River water quality good?
The Merrimack has improved significantly from its industrial-era pollution, but it still carries organic material, upstream discharges, and traces of PFAS. Lowell's treatment plant processes the water, but some disinfection byproducts (HAA5, TTHM) are unavoidable with river source water.
What water filter is best for Lowell?
A reverse osmosis system is ideal for Lowell water because it addresses all the concerns: lead from old pipes, HAA5 and TTHM from river water treatment, and PFAS from upstream sources. It's the most comprehensive single solution.
