25 October 2016 <br />AGE Project No. 11-1847 <br />Page 3 of 8 <br />Geoprobee 5400 equipped with 1.25-inch probing rods will be utilized. The total depth of <br />each well boring may vary according to geologic/hydrogeologic conditions encountered <br />during drilling. Locations of the soil borings and groundwater monitoring wells are as <br />follows: <br />Groundwater monitoring well MW-11 will be located approximately 45 feet east of <br />monitoring well MW-4 in the City right-of-way (alley road) near the eastern property <br />boundary to evaluate the deep eastward extent of the dissolved hydrocarbon <br />plume; <br />Groundwater monitoring well MW-12 will be located approximately 500 feet east- <br />northeast of site monitoring well MW-4 in the City right-of-way (sidewalk) near the <br />northeast intersection of San Joaquin Street and 8th street to evaluate the deep <br />eastward-northeastward extent of the dissolved hydrocarbon plume; <br />Groundwater monitoring well MW-13 will be located approximately 500 feet east- <br />northeast of site monitoring well MW-4 in the City right-of-way (sidewalk) near the <br />northeast intersection of San Joaquin Street and 8th street to evaluate the shallow <br />eastward-northeastward extent of the dissolved hydrocarbon plume; <br />Soil boring B-10 will be located approximately 5-10 feet northeast of former Tank <br />#1, and is located to evaluate soil for dermal contact risk at depths between 0-5 <br />feet, to evaluate soil for waste oil impact, and to assess intermediate groundwater <br />at depths between 55 and 65 feet bsg; <br />Soil boring B-11 will be located approximately 10 feet southwest of Tank #1, and <br />is located to evaluate soil for waste oil impact, and to evaluate soil for dermal <br />contact risk at depths between 0-5 feet; <br />Soil boring B-12 will be located approximately 5-10 feet east of Tank #2, and is <br />located to evaluate soil for dermal contact risk at depths between 0-5 feet; <br />Soil boring B-13 will be located approximately 20 feet north of well MW-6, and is <br />located to evaluate soil for dermal contact risk at depths between 0-5 feet; <br />Soil boring B-14 will be located approximately 450 feet east-northeast of soil boring <br />B-8, and to fully define the downgradient lateral and vertical extent of hydrocarbon- <br />impacted groundwater previously reported from B-8; <br />Soil boring B-15 will be located approximately 475 feet east-southeast of soil <br />boring B-8, and to fully define the downgradient lateral and vertical extent of <br />hydrocarbon-impacted groundwater previously reported from B-8; <br />Soil boring B-16 will be located approximately 525 feet east of soil boring B-7, and <br />to fully define the downgradient lateral and vertical extent of hydrocarbon-impacted <br />groundwater previously reported from B-7 and <br />Soil boring B-17 will be located approximately 700 feet southeast of soil boring <br />B-7, and to fully define the downgradient lateral and vertical extent of hydrocarbon- <br />impacted groundwater previously reported from B-8. <br />Advanced GeoEnvironmental Inc.
