RAMB LL ENVIRON ENVIRONMENT & HEALTH Proposed Limited Phase II Sampling: BCI Coca-Cola Bottling Company of Los Angeles LLC, Stockton, California Purpose: Soil and groundwater samples will be collected from the property at 1467 El Pinal Drive in Stockton, California (the "site") to evaluate potential contamination at the site related to fleet maintenance operations and the presence of below grade features. Fleet Maintenance Operations and Below-Grade Features at the Site: The site was first developed in 1990 for the distribution of soft drinks and fleet maintenance including truck washing. Wastewater generated from the fleet maintenance building (floor wash water) is routed through a subsurface wastewater treatment system of clarifiers and oil/water separators (OWSs) located adjacent to the building. Vehicle washing was historically conducted in the fleet maintenance building until approximately 2014, and the wash water was discharged to the sanitary sewer system. Vehicle washing activities are currently performed on site by a third party contractor who collects the wash water within aboveground barriers, vacuums and transports it off-site for disposal . SCOPE OF SERVICES Health and Safety Plan (HASP) development and underground utility locating. Prior to sampling of soil and groundwater at the site, a site-specific HASP will be developed and followed by all field personnel conducting work related to this limited Phase II investigation. Additionally, RamboII Environ will notify the state underground utility protection service to identify on-site commercial and municipal utilities, as well as contract with a private utility locator to identify subsurface hazards in the areas surrounding sampling locations. Soil Boring and Temporary Groundwater Monitoring Well Installation. To evaluate the soil and groundwater quality as a result of the fleet maintenance operations and the presence of below grade features at the site, RamboII Environ proposes to advance four soil borings and install temporary groundwater monitoring wells at each of the soil boring locations. Soil borings will be advanced using direct-push technology (DPT) to depths of approximately 5 feet below the water table, or to a depth of 50 feet below ground surface (bgs), whichever is reached first. Soils will be continuously collected from the approximately 2-inch diameter borings using Macro-Core or Dual Tube sampling systems. Soils characteristics will be recorded in the field and screened for total volatile organic compounds (VOCs) using a photoionization detector (PID). A soil sample will be collected from the depth interval with the greatest evidence of impacts. An additional soil sample may be collected below the interval exhibiting the greatest evidence of impacts to potentially vertically delineate impacted soil. If no evidence of impacts is observed, the samples will be collected from the direct contact zone (approximately 0-2 ft bgs), and from the depth interval above the groundwater table, and/or from the boring terminus if groundwater is not encountered. All non-disposable sampling equipment in contact with soils will be decontaminated prior to use at each boring location. Following soil sampling, a temporary groundwater monitoring well will be installed at each boring location using 1-inch diameter polyvinyl chloride (PVC) riser with a 10-slot screen, assuming groundwater has been reached within the predetermined maximum boring depth of 50 feet. Groundwater samples will be collected using a pump and disposable tubing. Samples will be collected in lab-provided containers with preservatives, and stored in ice-packed coolers for transportation to the laboratory. If the rate of groundwater recharge precludes the use of a pump, the sample will be collected using a disposable bailer.
