About Huntersville's Water Supply
Water Utility: Charlotte Water
Water Source: Mountain Island Lake (Groundwater)
Population Served: 582
Hardness: 42 PPM (2.5 grains per gallon)
Huntersville draws its drinking water from groundwater sources — Mountain Island Lake. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 582 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Charlotte Water's Consumer Confidence Report (CCR) or test your own tap.
