Danvers Water Hardness & Quality Report (2026)

The Danvers Water Department, operating from 1 Sylvan Street (mailing: 30 Lake St, Middleton, MA), serves approximately 36,043 residents in Danvers, Massachusetts, within Essex County. The utility draws its supply exclusively from surface water sources, primarily reservoirs such as Middleton Pond, treated at conventional facilities using hypochlorite disinfection. Contact is available via 978-777-0001 or 978-774-5054. Annual Water Quality Reports, or Consumer Confidence Reports, are published on the official site at danversma.gov, covering compliance and testing details for the community.

The supply is protected within the Ipswich River watershed, a key drainage basin spanning multiple reservoirs and tributaries in northeastern Massachusetts. Underlying geology includes Pleistocene glacial deposits — till, eskers, and outwash from the Wisconsinan glaciation — over Carboniferous-age bedrock of the Boston Basin sequence, including metamorphosed sandstones, shales, and volcanic rocks of the Mattapan Volcanic Complex and Roxbury Conglomerate. Natural leaching of calcium and magnesium from these sedimentary and metamorphic layers, combined with surface runoff over till and outwash plains, imparts a moderately mineralised character without reliance on deep aquifers.

At moderately hard levels, scale buildup affects water heaters, dishwashers, and washing machines most, reducing efficiency and leaving spots on glassware and films on fixtures. Regular vinegar descaling, sediment filters, and biannual heater flushing are recommended; a water softener helps households experiencing soap scum or dry skin. Testing notes four contaminants exceeding EPA health-based guidelines — Heptachlor epoxide, 1,1-Dichloroethylene, Dichloromethane, and Fluoride per tapwaterdata.com analysis. The utility maintains lead and copper compliance via corrosion control, with full metrics in annual CCRs at danversma.gov.
