ILd <br /> Mfr>, INTERIM INVESTIGATION & <br /> f=- EVALUATION REPORT AND <br /> PROJECT STATUS REPORT OF <br /> GROUND WATER MONITORING <br /> Village West Marina <br /> 6649 Embarcadero Drive <br /> Stockton, California 95209 <br /> LO INTRODUCTION <br /> The assessment work discussed herein was conducted in accordance with the Workplan <br /> Addendum for the Completion of Three Monitoring Wells at the Village West Marina dated <br /> May 23, 1994, prepared by W.W. Irwin, Inc. and approved by the Environmental Health <br /> Division of the San Joaquin County Public Health Services (SJCPHS-EHD). This Interim <br /> Evaluation and Assessment Re ort and Project Status Report of Ground-Water Monitoring <br /> includes the analytical results of soil and ground-water samples collected during and <br /> -: subsequent to the drilling of three soil borings completed as monitoring wells on June 6, <br /> 1994. <br /> 1.1 Site Setting <br /> The property is located at 6649 Embarcadero Drive in Stockton, San Joaquin County, <br /> California and is situated on the delta levee of the section of the San Joaquin River called <br /> -� Fourteen-Mile Slough as shown on the Vicinity Map, Figure 1. The site includes a <br /> restaurant and an operational marina with the capacity to dispense fuel to pleasure craft. <br /> The adjacent properties consist of other commercial businesses and residences. <br /> 1.2 Geologic Setting <br /> -: The site is located within the delta region of the San Joaquin River on Fourteen-Mile <br /> Slough. The surface elevation is about nine (9) feet above Mean Sea Level. The slough <br /> is situated north and adjacent to the project area at an elevation below the former <br /> underground storage tank invert. <br /> The lithology encountered during the drilling of the three soil borings (prior to completion <br /> as monitoring wells) consisted predominantly of black-gray, micaceous, organic clayey silt <br /> to the total depth in each well of approximately 30 feet below surface grade (bsg). Ground <br /> water was encountered during the drilling process at about 18 feet bsg in the borings. <br /> Generally, the quality of the water is considered poor. <br /> W.W.Irwin,Inc. <br /> Project No. 33016.03 <br /> 1 July 1994 1 <br />
