Iredell County – Statesville and Mooresville – serves about 190,000 residents north of Charlotte. Water comes from the Catawba River system through Lake Norman, the largest man-made body of freshwater in North Carolina. Mooresville's position on Lake Norman's southern shore has driven rapid growth.
Lake Norman's size provides a stable, abundant water source. UCMR5 data shows minimal PFAS detections. According to NC DEQ monitoring, Lake Norman water quality is generally good, though residential development around the lake's shoreline has increased nutrient loading in some coves.
Duke Energy's McGuire Nuclear Station sits on Lake Norman and uses lake water for cooling. The nuclear station operates under strict NRC monitoring requirements, and no contamination of the drinking water supply from nuclear operations has been documented.
