Analysis

What to know about Bellingham's water

Bellingham ranks #219 out of 280 cities in Massachusetts for water quality, placing it among the lowest-rated in the state.

Bellingham relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.

Hexavalent chromium (chromium-6) was detected at 0.39 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

What Bellingham residents can do

Install a water filter

Recommended: Reverse osmosis system. This addresses the specific contaminants found in Bellingham's water.

Request your utility's CCR

Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.

Flush your taps

Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.

Monitor alerts during storms

Bellingham's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.

Where Bellingham's water comes from

Groundwater

Bellingham's drinking water is drawn from underground aquifers through wells.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.

Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.

The system is operated by local government ownership and serves approximately 16,061 people through 1 water system.

Frequently asked questions

Is Bellingham, MA tap water safe to drink?

Bellingham's water quality earned a grade of B- (74/100). Some concerns have been identified. Consider a water filter for an extra layer of protection. The city ranks #219 out of 280 cities tested in Massachusetts.

What contaminants are in Bellingham's water?

Lead was measured at 3.6 ppb (90th percentile). 3 PFAS compounds were detected. 38 violations are on record.

How is Bellingham's water quality grade calculated?

The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.

Do I need a water filter in Bellingham?

PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.

Where does Bellingham's water come from?

Bellingham's water is sourced from Groundwater. The city has 1 water system serving approximately 16,061 residents.

What health violations has Bellingham's water system had?

Bellingham has 21 health-based violations on record. The most recent violation was recorded in September 2022. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 2 violations remain unresolved.

Is Bellingham's groundwater at risk of contamination?

Bellingham uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 38 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.

Why does Bellingham have so many PFAS compounds in its water?

3 different PFAS "forever chemical" compounds were detected in Bellingham's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.

How does Bellingham's water compare to other cities?

Bellingham ranks #219 out of 280 cities in Massachusetts (better than 22% of state cities) and #9947 out of 15744 cities nationally (37th percentile). The grade of B- reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
