About one in 5 households in Cabarrus County relies on a private well, around 15,145 homes. Outside the towns with public water, wells are the norm here.
In North Carolina the county is the front door: Cabarrus County Environmental Health permits the well, requires the 30-day test on a new well, and will collect a sample for the State Laboratory of Public Health for a county fee. The state’s testing schedule is in the cards below.
Every newly constructed private well must be tested within 30 days of completion by the State Laboratory of Public Health or a certified lab before it is used for drinking water.
No statewide requirement at sale. Lenders (FHA, VA, USDA) usually require a test.
Every year: total and fecal coliform bacteria plus a wellhead inspection. Every 2 years: heavy metals, nitrate and nitrite, lead and copper. Every 5 years: pesticides and volatile organic compounds. Retest after repairs, flooding, a change in water quality, or when an infant or pregnant person is in the home.
County health departments collect samples and send them to the State Laboratory of Public Health at set fees that vary by county (often $30 to $100 per panel).
