Where Does Northampton's Water Come From?
Water Source
Roberts Meadow Reservoir and lead mine wells (local groundwater)
Northampton, home to Smith College and a vibrant downtown, draws its water from the Roberts Meadow Reservoir and supplemental groundwater wells. As a college town with a mix of historic and newer buildings, water quality varies significantly depending on the age of your home and its distance from the treatment facility.
What's in Northampton's Water?
Based on water quality reports, testing data, and environmental assessments, these are the contaminants of concern for Northampton residents:
HAA5 (Haloacetic Acids)
Status: Detected — Surface water byproducts
Surface water from Roberts Meadow Reservoir requires chlorine disinfection, creating HAA5 byproducts. Levels fluctuate with seasons and water temperature.
Lead
Status: Risk in downtown & historic homes
Northampton's charming historic homes often harbor lead plumbing. Buildings near Main Street and in the Hill neighborhoods may have lead service lines predating modern standards.
Manganese
Status: Naturally present in groundwater
Local groundwater wells contain natural manganese from the Connecticut River valley geology. While primarily an aesthetic issue, high levels have health implications.
Chromium-6
Status: Detected above EWG guidelines
Like many MA communities, hexavalent chromium has been detected at levels exceeding Environmental Working Group health guidelines.
Health Risks for Northampton Residents
According to the EPA and Environmental Working Group (EWG), prolonged exposure to contaminants found in Northampton's water may increase risk of:
- • Developmental Risk: Students and young families in Northampton should be especially aware of lead exposure from old rentals and dormitory-adjacent housing
- • Cancer Risk: HAA5 and Chromium-6 are both associated with increased cancer risk over time
- • Neurological Effects: Manganese at elevated levels can affect neurological function, particularly in children
📍 Northampton Local Tip
College students renting in Northampton — your landlord might not mention water quality. Many downtown apartments are in converted Victorian homes with original plumbing. A countertop or under-sink RO system is a smart investment for your rental. You can take it with you when you move!

Is Northampton MA water safe to drink?
Northampton water meets federal standards, but detected HAA5, Chromium-6, and lead risk in older homes mean filtration is a smart precaution — especially for renters in historic buildings who may not know the age of their plumbing.
Does Smith College area have good water quality?
The Smith College neighborhood has a mix of old and newer housing. Campus buildings are generally well-maintained, but off-campus rentals in the surrounding historic district may have older plumbing with lead concerns. Always test your tap water in a rental.
Is there lead in Northampton water?
Lead can enter the water from home plumbing, not typically from the municipal supply itself. Northampton's many pre-1950 homes and apartments are at risk. Contact the Northampton DPW for a free lead test kit.
What filter works best for Northampton water?
A reverse osmosis system handles all of Northampton's contaminants of concern. For renters, a portable countertop RO unit (like the AquaTru) is a great option that doesn't require permanent installation.
