City of Ramsey <br /> Project 61700969 <br /> March XX,2017 <br /> Page 4 <br /> DRAFT <br /> ■ Installed five temporary monitoring wells in five of the soil borings(S-1,S-4,S-6,S-8,and S-9) <br /> and collected groundwater samples. <br /> ■ Installed three temporary soil vapor probes(SG-1 through SG-3) and collected soil vapor <br /> samples. <br /> ■ Conducted environmental monitoring during drilling and screened soil samples collected <br /> from the borings for the presence of organic vapors using a photoionization detector(PID). <br /> Visual and olfactory observations regarding potential contamination were also made and <br /> recorded. <br /> ■ Analyzed representative samples of soil,vapor,and groundwater for one or more of the <br /> following parameters:Volatile organic compounds(VOCs), polycyclic aromatic hydrocarbons <br /> (PAHs),gasoline range organics(GRO),diesel range organics(DRO),and Resource <br /> Conservation and Recovery Act(RCRA) metals. <br /> ■ Evaluated the data and prepared this report. <br /> Investigation locations are shown on Figure 2 and soil boring logs are included in Appendix A. <br /> D. Deviations from Work Plan/Proposal <br /> The proposal included 12 soil borings: 5 to be completed as temporary monitoring wells and 7 to be <br /> advanced by the former fueling dispensers. However,sampling under the dispensers was conducted as <br /> part of the concurrent tank removal activities. Instead of the 7 dispenser borings,4 shallow(8 feet deep) <br /> soil borings were advanced for general coverage of the Site. <br /> E. Investigation Methods and Procedures <br /> The field work relating to the Phase II ESA investigation was conducted on March 13,2017. Prior to <br /> beginning the field investigation, public utilities were cleared through Gopher State One Call and private <br /> utilities were cleared through a subcontracted private utility locator. <br /> Soil boring rationale and analytical testing parameters are summarized in Section E.1.c.The locations and <br /> ground surface elevations of soil borings,temporary monitoring wells,and soil vapor probes were <br /> BRAUN <br /> INTERTEC <br />
