How can we locate a fuel leak in a piping system without major excavation or complete pipe replacement?

Locating a leak in secondary containment piping is difficult to do in below-ground piping systems, where leaks are collected in a low-point sump. For existing sites, contact your local DEP Division for a referral to an organization that can perform leak location services. For new designs, you may consider a continuous leak monitoring system to pinpoint the exact location of a leak, should it ever develop.
