What Makes Westford's Water Unique?
Local geology and source profile
The Westford Water Department serves the town of Westford, Massachusetts, in Middlesex County. The utility operates two primary treatment facilities — the Forge Village treatment plant and the Nutting Road facility — and sources water from groundwater wells throughout the town, including the recently activated Stepinski well, all drawing from the Stony Brook watershed aquifer system. Treatment processes include standard groundwater disinfection and distribution system monitoring to meet federal and state drinking water standards for the town's mixed residential and commercial customer base.
Westford's water supply originates from a primary drinking water aquifer underlying the Stony Brook watershed, fed by fourteen public water supply wells. The groundwater is classified as groundwater under the influence of surface water. Massachusetts' glacial geology, combined with the mineral-rich aquifer composition, naturally produces water with elevated dissolved calcium and magnesium content. This results in a moderately hard supply in areas served by the Forge Village plant, with hardness increasing in some northeastern sections served by the Nutting Road facility following recent well additions.
At moderately hard levels, white mineral deposits accumulate on faucets, showerheads, and inside appliances such as dishwashers and washing machines, while plumbing and hot water heaters may experience reduced efficiency and lifespan from scale buildup. The utility notes large-scale treatment is currently cost-prohibitive; individual homeowners may benefit from point-of-use or whole-house water softeners using ion-exchange technology to remove calcium and magnesium minerals. The 2026 water quality report indicates a grade of C (42/100), with notable detections of PFOA and elevated copper and lead at the 90th percentile; two contaminants exceed EPA legal limits and 19 EPA violations are on record, with the department recommending customers consider water filters for additional protection.
Geology & Source: Stony Brook watershed aquifer — fourteen wells in Massachusetts glacial geology; groundwater under influence of surface water; elevated dissolved calcium and magnesium from glacial deposits yield moderately hard water

Data Sources & Methodology
Water quality data for Westford is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
