To: SAN JOAQUIN COUNTY ENVIRONMENTAL HEALTH DEPARTMENT <br /> Sub: Boring Permit Application—2546 French Camp Turnpike, Stockton, CA <br /> A Phase II Subsurface Investigation Proposal dated September 20, 2021, proposing the field <br /> activities to collect groundwater samples from three soil borings was prepared by Fulcrum <br /> Resources Environmental. The objective of drilling and sampling of groundwater in the soil <br /> borings is to investigate subsurface conditions at the subject property. The proposed soil <br /> boringlocations are shown on Figure 1. <br /> Direct push drilling equipment will be utilized to advance borings to 3 feet below first <br /> groundwater at approximately 25 feet (bgs). Borehole groundwater samples will be <br /> collected via temporary monitoring wells using dedicated Teflon and Masterflex tubing and <br /> a low-flow peristaltic pump. Following collection of samples, all boreholes will be backfilled <br /> with neat cement, using a tremie if over 30 feet, and restored to pre-drilling condition by <br /> applying patching materials. <br /> Should you have any questions, please feel free to contact Mr. Forest Kan at <br /> forest@frenviro.com. <br /> Sincerely, <br /> Forest Kan <br /> Staff Geologist, Fulcrum Resources Environmental <br /> ATTACHMENT <br /> FIGURE 1 SITE MAP WITH PROPOSED LOCATIONS <br /> • — �r Fulcrum Resources Environmental <br />
