An enhanced leak detection test is required within how many feet of a public drinking well?

500 feet

750 feet

1000 feet

An enhanced leak detection test is required within 1,000 feet of a public drinking well due to the need to protect groundwater resources from potential contamination. This distance is established to ensure that any leaks from underground storage tanks (USTs) are detected and addressed promptly before they can affect the water supply. The requirement reflects the importance of maintaining safe drinking water standards and the elevated risk that leaks pose to public health when they occur near drinking water sources. The 1,000-foot radius is a precautionary measure to safeguard the groundwater that communities rely on, ensuring that contamination is minimized or prevented entirely.
