Storrs Water Hardness & Quality Report (2026)

Storrs, Connecticut, gets its drinking water from the Connecticut Water Company, which manages the Mansfield system. This supply comes entirely from groundwater drawn from local wellfields. The water is treated at local facilities, where a small amount of sodium hydroxide is added to adjust the pH and prevent pipe corrosion. For detailed information on water quality and testing, customers can review the annual Consumer Confidence Reports available on the Connecticut Water Company website or by phone. The recharge areas for these groundwater sources are primarily forested and protected from development, contributing to the naturally high quality of the raw water.

The groundwater originates in the fractured crystalline bedrock aquifer of eastern Connecticut, found within the Eastern Highlands. This aquifer is composed of metamorphic and igneous rocks, including gneiss and granite formations belonging to the Merrimack Synclinorium. These ancient bedrock types naturally release calcium and magnesium as groundwater flows through fractures, giving the water its characteristic hardness. While glacial deposits do cover the bedrock, they offer little in the way of softening the water supply.

Homeowners in Storrs may notice scale buildup in appliances like water heaters and coffee makers, which can reduce their efficiency and lifespan. You might also find stubborn deposits on faucets and fixtures, and laundry might not come out as bright. Descaling water heaters annually can help, and many residents find that installing a whole-house water softener significantly extends appliance life and improves cleaning. The Connecticut Water Company primarily uses pH adjustment with sodium hydroxide to protect the distribution system from corrosion, and the groundwater itself requires minimal treatment beyond this.
