Reasons to test your well water

Do you rely on a well on your property for drinking or other purposes? You need to test your water regularly to make sure your family and loved ones can stay healthy.

Did you know what over 15 million households in the United States obtain their drinking water from their own private well. The use of water from these wells are not covered by the Environmental Protection Agency (EPA) regulations that are meant to safeguard public drinking water systems.

Although the US has one of the safest drinking water supplies in the world, sources of drinking water can still become contaminated through naturally occurring chemicals and minerals (for example, arsenic, radon), local land use practices (for example, pesticides, chemicals, animal feeding operations), malfunctioning wastewater treatment systems (for example, sewer overflows), and other sources. Contamination of a private well can impact not only the household served by the well, but also nearby households using the same aquifer.
