Cabarrus County, North Carolina: drinking water report. Cabarrus County – Concord and Kannapolis – serves about 230,000 residents northeast of Charlotte.
Cabarrus County – Concord and Kannapolis – serves about 230,000 residents northeast of Charlotte. Water comes from the Catawba River system through the Coddle Creek Water Treatment Plant and from the Rocky River, supplemented by interconnections with Charlotte Water.
Cabarrus County's Catawba River connection means it shares the same source water dynamics as Charlotte – including the coal ash legacy from Duke Energy's retired plants along the river. UCMR5 data shows low-level PFAS detections in county systems.
According to NC DEQ's 2024 monitoring data, county systems met all federal standards. The coal ash issue is the primary long-term concern, as heavy metals from ash ponds can leach into groundwater and surface water near former plant sites.
Cabarrus County's water quality is generally good. The coal ash situation upstream is worth tracking as cleanup progresses.
