Abington Water Hardness & Quality Report (2026)

The Abington Rockland Joint Water Works provides essential drinking water to approximately 32,867 residents across Abington and Rockland, Massachusetts. Their supply is a blend drawn from both groundwater and surface water sources. Four gravel-packed wells located on Myers Avenue tap into glacial aquifers, while surface water comes from the John F. Hannigan Memorial Reservoir in Rockland and Great Sandy Bottom Pond in Pembroke. Both surface and groundwater undergo treatment processes at dedicated facilities, including the Hingham Street Water Treatment Plant, before reaching homes.

These water sources are geographically situated within the North River watershed, which ultimately flows into the larger Massachusetts Bay drainage basin. The groundwater wells draw from aquifers formed by glacial sands and gravels. Surface water, however, flows over the Avalonia composite terrane, a geological region characterized by ancient granites, gneisses, and schists. Crucially, this bedrock contains very little limestone or other carbonate formations, meaning minerals like calcium and magnesium don't easily dissolve into the water, leading to its naturally soft quality.

Because the water is naturally soft, homeowners typically won't encounter significant issues with limescale buildup in appliances like water heaters or dishwashers, which can help extend their lifespan. You'll likely notice that soaps and detergents are more effective, so you might use less product for cleaning. A water softener isn't generally recommended, as it could potentially make the water too soft and lead to corrosion in your plumbing. Instead, occasional rinsing of fixtures with vinegar can help manage any minor residues. The Abington Rockland Joint Water Works monitors water quality closely, though they did exceed the state's PFAS6 standard at the Hingham Street Plant in Q2 2025; compliant water is available at a utility-provided filling station.
