For well owners specifically, the Environmental Protection Agency (EPA) and Department of Environmental Protection (DEP) recommend having your water tested at least one time per year as levels and contaminants can vary over time. For those on public water, even treated water can contain trace contaminants. While they may be “safe” according to regulations, public water may still have contaminants, such as hardness or chlorine residuals that can impact taste, skin health, and appliance efficiency. Occasional home testing allows you to detect and address these minerals and contaminants as well as customize a filtration system for your specific needs, ensuring you get the healthiest water for your home.
