lese area is adjacent to a former septic system and may be within the leach area associated with this subsurface feature. Groundwater is reportedly encountered at roughly 40 feet bgs. However, historical data suggests that groundwater at the subject property has been as shallow as 25 feet bgs in the past Contaminant plume delineation data indicates that the proposed ground lease and WTS facility location are near the southwestern edge of the impacted groundwater zone. Groundwater monitoring wells are situated within 75 feet of the proposed lease area. However, based upon recent geotechnical investigation of the host property, it is unlikely that shallow groundwater would be encountered during construction of a pier foundation for the proposed monopole. Based upon the information obtained during a Phase I Environmental Site Assessment (ESA), preconstruction sampling of soil and groundwater (if encountered) was recommended to determine if impacted soil and/or groundwater may be encountered during construction. 2.0 Purpose and Scope of the Investigation 2.1 Purpose The purpose and scope of the project is to take soil samples at two locations identified on Figure 2 and conduct laboratory analysis for the presence of Volatile Organic Compounds (VOC) and Total Petroleum Hydrocarbons (TPH) Diesel Range Organics (DRO) and Gasoline Range Organics (GRO). The scope of work will consist of the following: Collecting soil samples from two boring locations; Analyzing soil samples and groundwater (if encountered) for VOC using EPA Method 8260 and TPH-GRO and TPH-DRO by EPA Method 8015; and Preparing a sample report of site activities and analytical results. 2.2 Drilling and Sampling Procedures Two direct push borings would be advanced in the proposed lease area and along the proposed trench route. The lease area boring would be advanced to a depth of 25 to 30 feet below ground surface (bgs) and the trench route boring would be advanced to a depth of 5 to 10 feet bgs. At each boring location soil samples would be continuously collected using a two-inch diameter direct push sampling probe run by RSI Drilling of Woodland, California. The sampling probe would be lined with disposable acetate liners; soil samples will be collected in the liners which are then removed from the probe and opened for review of the soil. Soil samples would be reviewed for visual and olfactory evidence of impact; areas of soil with indications of potential impact would collected for analysis and if no indications of impact were observed soil samples would be collected near the total depth of the boring. If groundwater is encountered a groundwater sample was also collected using disposable polyethelyene tubing and a pump; groundwater is not expected to be encountered as a geotechnical investigation at the site did not encounter groundwater. Several monitoring wells are present on the site. One monitoring well is located northeast of the proposed trench route and, if accessible, will also be sampled using a disposable polyethylene bailer and nylon rope. Soil and groundwater samples would be collected in new, specially cleaned containers provided by the analytical laboratory and specific to the analysis collected. Each sample container will be filled Work Plan Site Name: Connell Motors 2 e%uc_hm, Site Number: SC-13309A c"Allina
