City of Ramsey Project B1610732 January 10, 2017 Page 12 xylene (BTEX) and total lead; all analytical values were below the practical quantitation limit (PQL)with the exception of lead.The 20 cubic yards of stockpiled soil were later commingled with soil excavated from a nearby drainfield and was thinspread on the adjoining property to the north across the railroad tracks. Soils samples from the base of each excavation were collected and analyzed for DRO and BTEX. Samples from the bottom of the waste oil and fuel oil rank excavations did not indicate any residual petroleum compounds. One sample collected from the bottom of the motor oil tank(on the Site) nearest to the tank fill line and vent line had a DRO concentration of 68 parts per million (ppm). The motor oil tank excavation was backfilled and sealed with concrete. A hand boring was later advanced in the near the east end of the motor oil tank excavation; DRO and BTEX were not detected above the PQL. A Class V injection well drainfield was noted near the tank locations. The excavation report indicated that based on the field headspace readings and laboratory analyses,further remedial investigation associated with the removed tanks was not warranted at the time. B.5.b. Leak#7205 The information in the MPCA file was limited. A petroleum tank release was reported on February 23, 1994 following the discovery of contaminated soil in the area of a former pump island that was removed in the 1970s. Contamination was encountered in the upper 10 feet of soil. Four groundwater monitoring wells associated with the investigation of the release were abandoned on September 8, 1995. The MPCA closed the file on the reported release on September 26, 1995.The file apparently overlapped with the VIC file (VP4770). An excavation report dated October 7, 1994 for Leak#7205 was in the VIC VP4770 file. According to the excavation report, approximately 400 cubic yards of petroleum impacted soils were removed from the former dispensing island area (located on the Site) located south of the southeast corner of the former auto dealership building on July 19, 1994.The excavated soil was transported off-site to the adjoining property to the north across the railroad tracks for land application treatment.The excavation was completed to an average depth of 15 feet. Groundwater was encountered in the excavation at approximately 23 feet below ground surface. Soil samples were collected from the excavation sidewalls and bottom and were analyzed for GRO, BTEX and lead. GRO and BTEX were not detected above PQLs. Low levels of lead were detected in all five soil samples. B.5.c. Leak#14065 The information in the MPCA file was limited to a Public Water Supply Well Assessment dated January 2002. A well (Unique Well Number 165575)was located at the southwest corner of the former auto dealership building (the well was located approximately 60 feet west of the Site).The well was sampled in August 1993 and January 1994. In August 1993, a concentration of 0.6 ug/I of 1,4-dichlorobenzene was detected. In January 1994, concentrations of 2.1 ug/I of benzene, 0.3 ug/I of xylenes, and 1.0 ug/I of styrene were detected.The well was listed as inactive and the former auto dealership had been demolished and replaced with the existing retail strip mall.
