Murraysville Water Hardness & Quality Report (2026)

Murraysville, an unincorporated community within New Hanover County, North Carolina, relies on the Cape Fear Public Utility Authority for its water. The primary source is the Cape Fear River, treated at the Sweeney Water Treatment Plant. This surface water supply is supplemented by groundwater drawn from the Castle Hayne Aquifer through a network of well fields. The utility manages a substantial operation, treating around 40 million gallons daily to serve over 300,000 residents across New Hanover, Brunswick, and Pender counties.

The region's water originates from a mix of surface and groundwater sources influenced by its geological setting. The Cape Fear River flows through the coastal plain, interacting with Tertiary carbonate rock formations, specifically the Miocene Castle Hayne Limestone. Groundwater is extracted from the Castle Hayne Aquifer, a significant unconfined aquifer characterized by fossiliferous limestone formations. Dissolution of minerals from this limestone contributes to the water's character, but dilution from river inflows, which traverse unconsolidated sediments, helps to balance the overall mineral content.

Homeowners in Murraysville will likely notice that their water is gentle on appliances and plumbing. The water's soft nature means you won't typically see much scale buildup in your water heater, dishwasher, or on fixtures like showerheads, which can extend their lifespan. Soap and detergents lather up easily, and you won't need to worry about the taste or residue that hard water can leave. For the rare instance of light deposits, a simple rinse with vinegar usually does the trick. This lack of significant mineral content also contributes to energy savings by keeping pipes clear.
