Newburyport Water Hardness & Quality Report (2026)

The Newburyport Water Division, part of the city's Department of Public Services, supplies drinking water to approximately 18,000 residents in Newburyport, Massachusetts, within Essex County. The utility draws 80 percent of its supply from surface water sources including the Merrimack River and Artichoke River, treated at the local Water Treatment Plant. The remaining 20 percent comes from groundwater via two gravel-packed wells — Well 1 and Well 2 — along Ferry Road. Water Treatment Operations Superintendent Thomas D. Cusick Jr. can be reached at (978) 465-4466.

The watershed encompasses the lower Merrimack River basin, a major New England waterway draining from New Hampshire into the Atlantic, with contributions from the Artichoke River. Groundwater originates from shallow glacial aquifers in unconsolidated Quaternary sediments overlying Paleozoic bedrock of the Merrimack Synclinorium, featuring schist, granite, and carbonate-bearing formations. Limestone and dolomitic layers dissolve calcium and magnesium during infiltration, imparting a hard supply character. The blend with river water flowing over diverse terrains yields moderately mineralised water overall.

Hard water in Newburyport leads to scale buildup in pipes, water heaters, dishwashers, and washing machines — expect 20–30% higher energy use in affected appliances. Kettles and faucets show white deposits quickly. Maintenance includes annual descaling, vinegar soaks for showerheads, and magnetic treatments as local options like H2O Care suggest. A whole-house water softener is recommended. The 2024 Consumer Confidence Report confirms EPA compliance, though 4 contaminants are noted above health guidelines. PFAS6 levels are monitored under Massachusetts' strict 20 ppt MCL. Treatment involves filtration, disinfection, and corrosion control with pH adjustment for lead/copper rule compliance.
