Final answer:
Tanks without secondary containment that are near public drinking water wells generally require enhanced leak detection testing to prevent contamination of water sources, which aligns with EPA regulatory measures to ensure drinking water safety.
Step-by-step explanation:
The question relates to environmental regulations and practices to ensure the safety of public drinking water supplies, specifically in regard to the placement of tanks without secondary containment near water wells. This falls into the broader topic of Environmental Science, which deals with the impacts of human activities on the environment and includes aspects of law, policy, and engineering.
When it comes to drinking water safety, the statement that tanks without secondary containment located within a specific distance of a public drinking water Well require enhanced leak detection testing is generally true. The need for enhanced leak detection stems from the fact that tanks without secondary containment pose a higher risk of contaminating groundwater sources if they were to leak, and proximity to a public well amplifies that risk. As such, regulatory bodies like the Environmental Protection Agency (EPA) have put measures in place to prevent contamination of drinking water sources, including requiring tanks close to public wells to undergo more stringent testing. This mitigates the risk of waterborne diseases from contaminants, such as fecal matter leaking into groundwater from nearby cesspits or other sources.
