How often must individual underground storage tanks be tested for leaks?

Individual underground storage tanks must be tested for leaks every five years because this timeline aligns with regulatory and safety standards established to minimize the risk of environmental contamination and ensure the integrity of the tanks. Regular testing helps identify potential leaks early, reducing the likelihood of hazardous materials escaping into the surrounding soil and groundwater. This requirement is part of a broader compliance framework meant to protect both public health and the environment, ensuring that any issues are addressed before they become larger problems. The five-year interval is considered a balanced approach, providing enough time for maintenance while also being frequent enough to detect any potential issues that could arise.
