I <br />' Savin Royal Oak s & Loan <br /> y g <br /> 510 North Main Street, Manteca, CA <br /> Quarterly Groundwater Sampling Report <br /> April, 1992 <br /> Site Code #2393 <br /> NARRATIVE <br /> On April 9 1992 WHF Environmental Consaltants, Inc , in conjunction with HKM, <br /> I Inc , conducted field measurements, well pumping, and ground water sampling on <br /> three (3) groundwater monitoring wells located at this site <br /> Groundwater elevations were taken from all six (6) wells prior to pumping (Table 1) <br /> Each well was evacuated by means of a steam-cleaned, stainless steel bladder-type <br /> pump At least three (3) well volumes were pumped from each well During the three <br /> (3) volume pump down each well, samples were collected to measure the field phi, <br /> electrical conductivity and temperature Once stability was achieved and a minimum of <br /> three (3) well volumes were removed, the samples were collected The samples were <br /> then labeled and placed in an ice chest cooled with blue ice and crushed ice <br /> The samples were then logged on a Chain of Custody and transported to GeoAnalytical <br /> Laboratories, a State certified laboratory in Modesto, California The analysis reques- <br /> ted for the three (3) water samples was EPA method 602 for purgeable aromatic hydro- <br /> carbons and method 5030/LUFT for total petroleum hydrocarbons - gasoline The <br /> analytes and concentrations detected are listed in Table 2 of this report <br /> Water measurements were taken on March 20, 1992, and show the gradient direction to <br /> the northwest and southwest The measurements taken on April 9, 1992, show the <br /> gradient direction to be northeast and northwest Both maps are included in this report <br /> The groundwater elevations noted in this quarter's measurements are referenced on the <br /> groundwater chart in Table 1 of this report <br />
