The Site is located west of the downtown <br />business district in an area of office, commercial, light industrial, residential, educational, and recreational <br />uses. The Site parallels State Highway 4 one block to the south. <br />The Site is approximately in the yoke of the confluence of the Stockton Deep Water Channel which runs <br />east to west approximately three blocks north of the Site and the Mormon Slough which runs southeast to <br />northwest approximately three blocks south of the Site and due north approximately 1/2 block west of the <br />Site. <br />Storm water and surface water discharges by sheet flow to street gutter storm drains, and matriculates <br />directly into those undeveloped portions of the Site. <br />The shallow aquifer groundwater flow direction at the Site is away from the Stockton Deep Water Channel <br />and away from the Mormon Slough. The local groundwater system is being recharged from surface water <br />within the channel and slough. The shallow groundwater beneath the site is found greater than 6 feet below <br />ground surface. <br />In August 2001 a subsurface investigation of the area bounded by Market Street, Van Buren Street, <br />Washington Street, and Lincoln Street concluded that groundwater beneath this area exhibited a lead <br />concentration at 210 micrograms per liter (ug/L). Additionally, there may be LUST cases that might be <br />impacting the water channels surrounding the site, and consequently the shallow groundwater beneath the <br />site. <br />SCOPE of WORK <br />Drilling permit applications will be prepared and submitted to the San Joaquin County <br />Environmental Health Department for approval. <br />A site Health and Safety Plan (HASP) will be prepared by Earth Tech in accordance with the <br />Code of Federal Regulations (CFR), Part 29, 1910.120. The expected hazardous conditions to be <br />encountered, and measures to control and monitor these potential hazards in order to protect the <br />health and safety of consultant staff, subcontractors, and the public, will be specified in the <br />HASP. <br />Earth Tech will employ the services of a professional underground locator to investigate the <br />existence and location of underground utilities or obstructions in the vicinity of the proposed soil <br />boring locations. Underground Service Alert (USA) will also be notified.
