About Us


The quality of leak detection technologies employed by PetroMonitor for the monitoring and testing of underground storage tanks and lines has been independently tested and verified by appropriate third-party organisations. Our technologies are certified to the common standards required by regulatory bodies.

This website provides copies of third-party certifications and evaluation reports by leak detection manufacturers that have decided to make them available for download. Copies of listings by the EPA’s National Workgroup on Leak Detection Evaluations (NWGLDE) are also available for all KWA certified methods.

National Work Group

NWGLDE is an independent Work Group comprised of 11 members, 10 of whom represent various states and one from the U.S. EPA.  All of their members are state or federal employees whose full-time job is to regulate storage tanks for their agency’s regulatory program.
