July 29, 1997 0R <br /> 1)11c,)11c,11(m rl incurhu)ated <br /> Ms Anastasia Duarte-Wilkinson <br /> Tune Oil Company <br /> 2737 West Commodore Way <br /> Seattle, WA 98199 <br /> SUBJECT: Quarterly Monitoring Report, April- June 1997 <br /> Jackpot Food Mart <br /> 14000 East Highway 88 <br /> Lockeford, California <br /> Ms Duarte-Wilkinson <br /> This report presents the results of quarterly groundwater monitoring and sampling conducted at the Jackpot <br /> Food Mart at 14000 East Highway, Lockeford, California(the site, see Figure 1) <br /> GROUNDWATER MONITORING AND SAMPLING <br /> Ten groundwater monitor wells were sampled on April 16, 1997 at the site Monitor wells MW-1 through 1 <br /> MW-4 were installed as part of an environmental investigation conducted in December 1994 In July 1996, <br /> monitor wells MW-5 through MW-10 were installed as part of an additional environmental site assessment <br /> Prior to purging each groundwater monitor well, a water sample was taken and subjective analyses <br /> performed The subjective analyses consisted of checking for floating product or a hydrocarbon sheen by <br /> lowering a clean teflon bailer down the well and collecting a sample at the groundwater-air interface Wells { <br /> not containing floating product were purged of approximately 2 to 4 casing volumes of water or until <br /> groundwater parameters of pH, temperature, and conductivity stabilized as measured by portable meters 5 <br /> calibrated to a standard buffer and conductivity standard If the well was slow to recover or purged dry, the <br /> water level in the monitor well was allowed to recover to at least 80 percent of its static level before r <br /> sampling The groundwater samples were then collected by lowering a clean disposable bailer into the well <br /> and collecting a representative sample The groundwater samples were slowly transferred to laboratory- <br /> cleaned sample containers, sealed with teflon caps, labelled with the sample number, sample time and date, <br /> and immediately placed on ice in an insulated container Each sample was logged onto a chain-of-custody <br /> record for subsequent delivery to Excelchem Environmental Labs located in Roseville, California <br /> Groundwater samples were analyzed for TPHg, and BTEX, using modified EPA Method 8015, and EPA <br /> Method 602 respectively Additionally, two groundwater samples were analyzed for MTBE using EPA <br /> Method 602 Sample MW-11 was submitted as afield duplicate for monitor well MW-9 <br /> Groundwater Elevation Data <br /> Depth to groundwater was obtained from the existing groundwater monitor wells at the site using a water I <br /> level indicator graduated to 0 01 foot The depth to groundwater measurement was converted to a a <br /> groundwater elevation for each well and used to construct a potentiometric surface map (Figure 2), and <br /> calculate the local groundwater flow direction and hydraulic gradient The groundwater potentiometric ' <br /> surface elevation averaged approximately 74 23 feet below ground surface (bgs) during this monitoring <br /> event The groundwater flow direction at the site is directed toward the southwest with a hydraulic gradient , <br /> of approximately 0 02 (ft/ft) A summary of data regarding groundwater levels measured through April 16, <br /> SFCVR <br /> LCKFRI)gm 297 July 29 1997 <br /> J07I0-001-0) <br />
