Active received a call from a client asking if we could help with identifying a suspected UST in the basement of a commercial property. Active begin with our in-house Geophysicist identifying and marking out the UST location. It was identified at this point that the UST appeared to be a 1,000 gallon tank. Upon completion of the identification, Active returned to the site to collect soil samples from around and through the bottom of the UST. Sample results indicated that there were detections over standard and that the UST and impacted soil were going to need to be removed. Two major concerns with the project were vapors from the UST disrupting the business and structural support. To eliminate the vapor issue, Active created a containment around the work area under negative pressure and vented the work area 150 feet to the rear of the building, thus eliminating any indoor air quality issues. Once that was established, an engineer designed structural support and the Active team went to work. As material was excavated from the work area around the UST the structural support was constructed. All material was removed by hand and the UST was cut in pieces and removed. All impacted soil was staged and later disposed of at an off-site disposal facility. The UST was recycled. Upon approval from the client, Active backfilled the excavation with flowable fill utilizing a pump truck. All the work was performed during normal business hours without any interruption to the businesses.
