Michael Infurna , Jr. <br /> August 21, 2002 <br /> Page 2 of 5 <br /> SCOPE OF WORK <br /> The PHS-EHD has requested that soil and groundwater in the area of residual petroleum impact <br /> in the southeast corner of the former UST excavation be assessed.. The proposed scope to assess <br /> the area of the observed petroleum impact comprises the collection of fourteen soil and two <br /> groundwater samples from two borings. The locations of the two borings is shown in Figure 2. <br /> One boring (B-1) will be advanced at the location of the soil impact, and soil samples collected <br /> every five feet below ground surface(bgs),beginning at 10 feet bgs, until groundwater is <br /> encountered, anticipated to be approximately 50 feet bgs, for a total of nine soil samples. One <br /> grab-groundwater sample will be collected from the terminus of the boring. <br /> k <br /> The second boring (B-2) will be advanced approximately 15 feet northeast of the first boring (B- <br /> 1). Northeast is the apparent direction of groundwater flow, per three groundwater monitoring <br /> wells adjacent to the former 20,000-gallon USTs. Soil samples will be collected at 10-foot <br /> intervals from Boring B-2, beginning at 10 feet bgs, for a total of five samples. One grab- <br /> groundwater sample will be collected from the terminus of the boring. <br /> METHODOLOGIES <br /> The following project-specific methodologies will be employed in the field to execute the <br /> planned investigation activities. These methodologies are industry-standard, and incorporate <br /> federal, state and local requirements and guidance for the collection of viable environmental <br /> data. <br /> Permitting <br /> Permits will be obtained from the PHS-EHD for environmental borings. Other permit <br /> requirements are not anticipated. <br /> Underground Utility Clearance <br /> g Y <br /> As required by federal law, Underground Service Alert (USA) wilIbe notified 72-hours prior to <br /> field work. Boring locations will be marked in white paint to allow USA participants to identify <br /> known utilities in the boring areas. In private property areas, an underground utility location <br /> contractor will be used to locate subsurface features in boring areas. <br /> 3023-03!104700.4766.230/AUG2]'02 <br />
