Is Lawrence Water Safe to Drink?

Lawrence Water Quality Report & Filtration Solutions — 2026

📊

Current Status: Lawrence faces significant lead infrastructure challenges alongside Merrimack River source water concerns. The city's older housing stock creates elevated exposure risks.

Where Does Lawrence's Water Come From?

Water Source

Merrimack River (treated at city facilities)

Lawrence, another historic mill city on the Merrimack River, draws its water from the same river that powered its textile mills. The city's water treatment facility processes Merrimack River water, but the combination of a river source, extremely old infrastructure, and dense older housing creates one of the most challenging water quality environments in the state. Lawrence also serves neighboring communities.

What's in Lawrence's Water?

Based on water quality reports, testing data, and environmental assessments, these are the contaminants of concern for Lawrence residents:

Lead

Status: HIGH RISK — Historic mill city

Lawrence has extensive lead infrastructure dating to the 1800s mill era. The city's dense tenement housing, much of it a century or more old, frequently has lead service lines and lead-soldered interior plumbing. Lawrence has historically high childhood lead levels.

HAA5 (Haloacetic Acids)

Status: Detected — River source water

Merrimack River water contains organic matter that reacts with chlorine during treatment, forming HAA5. Lawrence's downstream location on the river means it receives water with accumulated organic material from upstream.

PFAS ("Forever Chemicals")

Status: Detected from Merrimack sources

PFAS enter the Merrimack from upstream industrial and municipal discharges. Lawrence's position downstream from several communities means cumulative PFAS exposure from the river source.

Microplastics

Status: Emerging concern — River source

As an emerging contaminant, microplastics in river source water are a growing concern. The Merrimack carries microplastics from upstream urban areas, and standard treatment may not fully remove them.

Health Risks for Lawrence Residents

According to the EPA and Environmental Working Group (EWG), prolonged exposure to contaminants found in Lawrence's water may increase risk of:

📍 Lawrence Local Tip

Lawrence families — your city has some of the highest childhood lead levels in Massachusetts. This comes from both water AND old lead paint, which is common in Lawrence's tenement buildings. An RO system for drinking water is critical, but also look into the city's lead paint abatement programs. For new parents: always use filtered water for baby formula. The Lawrence Water Department offers free lead test kits.

The Solution: Reverse Osmosis Filtration

Standard pitcher filters (like Brita) are not effective at removing Lead or most contaminants found in Lawrence's water. Water quality experts recommend a Reverse Osmosis (RO) system that can remove up to 99% of dissolved contaminants.

Why RO Works for Lawrence Water:

  • ✓ Removes 99%+ of Lead, HAA5, PFAS
  • ✓ 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

Frequently Asked Questions — Lawrence Water

Is Lawrence MA water safe to drink?

Lawrence water is treated and monitored, but the city's aging infrastructure means lead at the tap is a serious concern, especially in older homes. Combined with Merrimack River source water challenges, home filtration is strongly recommended for all Lawrence residents.

Why does Lawrence have high lead levels?

Lawrence was built as a mill city in the 1800s. Much of its dense tenement housing has never had plumbing fully replaced. Lead service lines, lead solder, and lead fixtures are common. The city also has high lead paint prevalence, creating dual exposure for residents, especially children.

Is the Merrimack River clean enough for drinking water?

The Merrimack has improved dramatically from the days when mills dumped waste directly into it, but it still carries organic material, PFAS from upstream sources, and emerging contaminants. Lawrence's water treatment processes the water, but some byproducts of treatment remain in the finished water.

What's the cheapest way to get safe water in Lawrence?

An under-sink reverse osmosis system costs $150-250 and provides the best protection for drinking and cooking water. That's less than $0.70/day over a year — far cheaper than bottled water. Models like the APEC ROES-50 are proven, affordable, and easy to install yourself.
