Well water testing

Testing your well water regularly is essential because private wells are not regulated by the federal government, making homeowners responsible for their own water safety

. At a minimum, experts recommend annual testing for coliform bacteria and nitrates. 

Recommended Testing Schedule

Routine testing helps establish a historical record of your water quality, which can be critical if nearby activities later damage your supply. NC State Extension Publications

• Annually (Spring is best): Test for coliform bacteria, nitrates, pH levels, and Total Dissolved Solids (TDS).
• Every 2–3 Years: Test for lead, arsenic, iron, manganese, chloride, and hardness.
• Immediate Testing: If you notice changes in taste, odor, or color, or after flooding, heavy rainfall, or well repairs.
