Well Water and other sources such as Spring Fed Reservoirs can become contaminated at any time without your knowledge. Regular well water testing or spring water testing is the only way that you can assure a clean supply of drinking water from these sources. The North Carolina Division of Public Health recommends testing well water every year for coliform bacteria, every two years for heavy metals, nitrates, nitrites, lead, copper, and volatile organic compounds, and every 5 years for pesticides. Mountains To Sea Inspections makes well water and spring water testing simple, fast and affordable.
