Based on ground-water gradients observed in a nearby portion of the Brookside Development site which indicated a southerly <br /> direction of ground-water flow toward the Calaveras River) , the <br /> two wells intended be vationstof the and the twokwellsvintended <br /> were placed south off the excath- <br /> to be upgradient of twaterclevelons were measurementseoftthehfourrwells <br /> northeast. However, <br /> installed around the tank excavations indicated that, contrary to <br /> expectations, the ground-water flow in this <br /> area <br /> und w was <br /> to the <br /> northwest. Consequently, to verify <br /> s not <br /> been affected directly downgradient of the tank excavations, the <br /> installation of two additional wells to the northwest <br /> (downgradient) of each tank excavation was recommended. <br /> PROPOSED SCOPE OF WORK <br /> This Scope of Work is proposed to assess the impact, if any, of <br /> fuel hydrocarbons on shallow ground water in Area 1 downgradient <br /> of the former locations of the underground gasoline storage <br /> tanks. Ground-water samples from the two newly installed wells <br /> will be analyzed for petroleum hydrocarbons and associated <br /> volatile organic compounds. <br /> The following describes the tasks involved in our proposed Scope <br /> of Work. <br /> Task 1: Location of Utilities <br /> Task 2: Installation of Two <br /> Shallow <br /> -Ground-Water Water nMgonitoring Wells <br /> Task 3 . Well Development <br /> Task 4: Laboratory Analysis <br /> Task 5: Data Evaluation and Report Preparation <br /> Task 6: Project Management and Meetings <br /> Detailed descriptions of each task follow. <br /> Task 1: Location of Utilities <br /> Prior to the drilling of the monitoring wells, each location will <br /> be checked for the presence of utility lines andsubsurface <br /> ques <br /> structures, to the extent possible, g geophysical <br /> provided by a professional locating service.
