Parallel Ave. , <br /> PER M1113/SEViCE;; <br /> Ripon, California <br /> Dear Mr. Peltier: <br /> During an investigation at the above referenced site (conducted <br /> as part of an environmental audit ) a leachfield which had <br /> received steam cleaning waste water, was discovered. <br /> A soil sample taken from under the leachlines at a depth of nine <br /> feet below grade showed low levels of oil and grease <br /> ( approximately 90 ppm) and no volatile organic priority <br /> pollutants. <br /> A single monitoring well was installed approximately 25 feet <br /> laterally in the down gradient direction to a depth of 45 feet. <br /> A soil sample collected at 30 feet (just above the water table) <br /> showed low levels of BTX. After the well was properly developed <br /> a water sample was taken for analysis and showed 5.0 mg/liter of <br /> oil and grease, but no purgeable hydrocarbons. These results are <br /> summarized in the attached letter report. Also attached is a <br /> phase one environmental audit which summarizes the initial soil <br /> sampling around the site. <br /> We request guidance from the Board in proceeding with this <br /> matter. The property owner and lender need to understand the <br /> Boards position with respect to any further work which may be <br /> required, or if the work done to date is sufficient to receive a <br /> letter of closure. <br /> Respectfull , <br /> W rWork <br /> Russell W.
