Private well owners are responsible for ensuring their water is safe to drink. Health departments recommend annual testing for coliform bacteria and nitrates at minimum, with additional testing for pH, hardness, iron, manganese, and other contaminants based on local geology and land use.
Well water quality can change over time due to seasonal fluctuations, nearby construction, agricultural activity, or aging well components. Regular testing catches problems early, before contaminated water causes health issues for your family.
Certified water testing labs analyze samples for a wide range of contaminants. Many septic and well service companies offer sampling services and can help interpret results and recommend treatment solutions when needed.
