The site investigation done using the Ground Penetrating Radar (GPR) system determined that there are two areas of concern that require further investigation. One of the two sites likely contains one but potentially two underground storage tanks. There are no records of tanks being placed or removed on the site and therefore we need to do further discovery to determine if these echoes are tanks or something else. Adjacent to the potential tank locations, the GPR discovered a section of "disturbed soils" that contained potentially unsuitable soils that were quantified and processed while doing the Geotechnical Probes for soil and ground water testing. The readings on the soils were not of great concern except for a pocket of materials near the depth of the probe which might need to be removed pending review of further results. A site investigation is being done on Wednesday (November 18th) to determine the final scope of work that might be associated with the potential tank locations and a copy of a revised proposal and staff report will be forwarded to you prior to this Friday's meeting.
