North Chicopee Water Hardness & Quality Report (2026)

The Chicopee Water Department (MWRA), serving Chicopee, Massachusetts — including North Chicopee — provides drinking water to approximately 55,000 residents in Hampden County. Water is sourced from surface water purchased from the Massachusetts Water Resources Authority (MWRA), drawn from the Quabbin and Wachusett Reservoirs via the MetroWest Water Supply Tunnel. Additional treatment occurs at the Chicopee Corrosion Control Facility and Brutsch Water Treatment Plant, where pH and alkalinity are adjusted before distribution.

The supply derives from the Chicopee River Basin within the larger Connecticut River watershed, spanning forested uplands and agricultural lowlands in central Massachusetts. The geology features crystalline Paleozoic metamorphic bedrock — schists, gneisses, and quartzites — overlain by Pleistocene glacial sediments. This setting yields a naturally soft supply with low mineralisation, as non-carbonate rocks limit calcium and magnesium ion leaching into the reservoirs feeding the system.

As a soft water supply, North Chicopee's water produces minimal scale buildup, posing low risk to appliances like water heaters, dishwashers, and pipes. Soap lathering is efficient and skin dryness is uncommon. No softener is needed; over-softening could overly strip minerals and may require remineralisation to prevent pipe corrosion. Finished water pH is approximately 8.0 after treatment with sodium carbonate and bicarbonate for corrosion control. Disinfection uses sodium hypochlorite and UV light, targeting 0.2 mg/L free chlorine, and the utility complies with lead and copper rules via pH and alkalinity optimisation. Annual Consumer Confidence Reports confirm full regulatory compliance.
