Failing to properly test line leak detectors can lead to potential environmental contamination. These detectors are crucial for identifying leaks in underground storage tank systems. If they are not functioning correctly due to inadequate testing or maintenance, even small leaks may go undetected. This can result in fuel, chemicals, or other hazardous substances leaking into the soil and groundwater, posing significant risks to the environment and public health. Environmental contamination can lead to costly remediation efforts, regulatory fines, and damage to ecosystems, making it imperative to ensure that line leak detectors are regularly tested and maintained to prevent such consequences.

The other options suggest benefits or issues that do not directly arise from the failure to test these important safety devices. For example, increased fuel efficiency is unrelated to leak detection, and while loss of fuel supply contracts may be a business concern, it is not a direct or immediate consequence of failing to properly test leak detectors.
