Three soil borings were advanced at the above-referenced site <br /> and were subsequently converted to monitoring wells on August 19, 1998. Analytical <br /> results of the soil sample taken at the lowest depth of 28.5 feet below surface grade <br /> (bsg) at Monitoring Well #1 (MW-1) were 3.9 parts per billion (ppb) of Total <br /> Petroleum Hydrocarbon as diesel (TPH-d), from MW-2 were 1,500 ppb of TPH-d and <br /> 870 ppb of TPH-gasoline (TPH-g), and from MW-3 were 12 ppb of TPH-d and 3.9 ppb <br /> of TPH-g. Analytical results of the water sample collected from MW-2 during the <br /> latest round of monitoring event were 36,000 ppb of TPH-d and 220 ppb of TPH-g, <br /> and from MW-3 the results were 380 ppb of TPH-d. Based on the last five quarterly <br /> monitoring reports (QMR), groundwater flow direction has been consistently <br /> southeastward toward the railroad track beyond the property boundary. The railroad <br /> track is owned by Burlington Northern Santa Fe Railway (BNSF). <br /> The Workplan for Additional Subsurface Investigation dated June 28, 1999 prepared by <br /> ATC to address the extent of the contamination plume was approved by this office on <br /> July 1, 1999. In a telephone conversation on August 18, 1999, ATC informed <br /> PHS/EHD that both you and ATC had been unable to obtain from BNSF a permit to <br /> encroach on their property to carry out the above-mentioned work. At the request of <br /> ATC, a letter dated August 25, 1999 from this office was mailed to you and a copy of it <br /> was sent to BNSF citing the statues requiring the investigation of the UST <br /> unauthorized release. The work has still not been performed. <br /> A Division of San Joaquin County Health Care Services <br />
