PROJECT STATUS REPORT OF <br /> E-` GROUND-WATER MONITORING - - <br /> Village West Marina <br /> 6649 Embarcadero Drive <br /> I Stockton, California 95209 <br /> - N � <br /> k � INTRODUCTION <br /> This Project Status Report of Ground-Water Monitorinu was conducted in accordance with the <br /> directives of the Environmental Health Division of the San Joaquin County Public Health <br /> Services (SJCPHS-EHD). It includes a background assessment history, ground-water sounding <br /> and flow direction/gradient data since July 1994, and laboratory analytical results for ground- <br /> water samples collected on September 19 and December 19, 1994. A sample of slough water <br /> was collected from near MW-6 on January 13, 1995. <br /> I Site Setting <br /> a The property is located at 6649 Embarcadero Drive in Stockton, San Joaquin County, California <br /> and is situated on the delta levee of the section of the San Joaquin River called Fourteen-Mile <br /> Slough as shown on the Vicinity Map, Figure 1. The site includes a restaurant and an <br /> operational marina with the capacity to dispense fuel to pleasure craft. The adjacent properties <br /> f> _ = consist of other commercial businesses and residences. <br /> jT Geologic Setting <br /> The site is located within the delta region of the San Joaquin River on Fourteen-Mile Slough. <br /> The surface elevation is about nine (9) feet above Mean Sea Level (AMSL). The slough is <br /> situated adjacent to the project area at an elevation below the former underground storage tank <br /> invert. <br /> c-. <br /> { The lithology encountered during the drilling of three soil borings (prior to completion as <br /> monitoring wells MW-4, MW-5, and MW-6) consisted predominantly of black-gray, micaceous, <br /> organic clayey silt to the total depth in each well of approximately 30 feet below surface grade <br /> (bsg). Ground water was encountered during the drilling process at about 18 feet bsg in the <br /> borings. Generally, the quality of the water is considered poor. <br /> r- <br /> W.W.
