Davidson County, North Carolina: drinking water report. Davidson County – Lexington and Thomasville – serves about 170,000 residents in the central
Davidson County – Lexington and Thomasville – serves about 170,000 residents in the central Piedmont. Water comes from the Yadkin River and High Rock Lake. The county's furniture manufacturing heritage has declined, but the economic and environmental legacy remains.
High Rock Lake, a reservoir on the Yadkin River, has experienced significant nutrient enrichment. The NC DEQ classified the lake as nutrient sensitive, and algal blooms are a recurring issue during warm months. Treatment plants must manage the additional organic content that algal growth produces.
UCMR5 data shows minimal PFAS detections in county systems. According to NC DEQ's 2024 data, county systems met federal standards. Disinfection byproduct management during bloom periods is the primary treatment challenge.
Davidson County's water meets standards, but algal bloom seasons bring more treatment variability.
