Underground Storage Tanks (USTs)
The EPA estimates that ~569,000 Underground Storage Tanks (USTs) nationwide store petroleum or hazardous substances. The greatest potential threat from a leaking UST is contamination of groundwater. Once a release event has occurred it is imperative that soils be remediated so that groundwater resources are protected. To determine the best method for soil remediation a site assessment is often required. EnTech has written industry standards for non-destructive brownfield testing methods to map plumes. The combined Infrared – Energy Pattern Analysis (IR-EPA) and Ground Penetrating Radar (GPR) approach identifies a release event and maps the extent accurately and efficiently.
