.. J <br /> 3r <br /> San Joaquin Workplan ' <br /> 3E <br /> Commence quarterly groundwater monitoring at the subject <br /> property of existing and proposed monitoring wells; and, <br /> Preparing a written report to present our findings, conclusions <br /> and recommendations. <br /> 4.0 TECHNICAL APPROACH <br /> Based upon review of previous investigation;conducted at the subject property <br /> and published data regarding local geographic and hydrologic conditions, <br /> Augeas Corporation developed the following technical approach for the <br /> proposed investigation. !? <br /> In order to accomplish the goals establish for the proposed investigation,the <br /> ". <br /> project would be separated into four distinct".work items as follows: <br /> I. Field Investigation to advance exploratory soil borings for the <br /> ' purpose of logging subsurface conditions and obtaining sub- <br /> soils samples for chemical analysis. Four soil borings will <br /> completed as groundwater rr onitonng wells.. <br /> U. Field Testing of aquifer ch�aractei'istics by means of slug- <br /> testing monitoring wells to evaluate general aquifer condi- <br /> tions. <br /> �I <br /> III. Laboratory analysis of subsoil 'and groundwater samples <br /> obtained from the field investigation to evaluate the presence <br /> ` and concentration of petroleum constituents contamination. <br /> { Selected subsoils will also be submitted for engineering analysis. <br /> ,t <br /> e <br /> IV. Report preparation summarizing the results of the chemical <br /> analysis and the evaluation sof applicable mitigating and/or <br /> remedial technologies appropriate for the site based upon data <br /> obtained from current and previous investigations. <br /> 'F <br /> 4 'Project Number: TOAQ22192 9 Page 4 of I I <br /> js <br /> { <br />
