How often must a well water supply be tested?

Well water supply testing is essential for ensuring the safety and quality of drinking water, particularly since private wells are not regulated in the same way that public water supplies are. Testing once per year is recommended because it allows for regular monitoring of the water quality, helping to identify any potential contaminants or changes in water composition due to environmental factors, such as runoff or changes in land use. Annual testing provides a proactive approach to managing water safety, ensuring that harmful substances like bacteria, nitrates, and other pollutants are not present at levels that could pose health risks. This frequency aligns with guidelines from health organizations, reflecting the importance of maintaining public health standards in communities relying on well water sources.
