Thank you for understanding
Many Americans receive their drinking water from private wells which are not regulated by the Environmental Protection Agency (EPA). Regular maintenance of your well is required to ensure continued safety of your water and to monitor for the presence of any contaminants.
The Public Health Water Laboratory offers a variety of tests for homeowners with private wells.
