Fremont St., Stockton, California. <br /> Pear Ms. Cotullat <br /> At the request of RAHCON, acting agent for Crystal Creamery and <br /> Butter Company, we are submitting this report of the chemical <br /> data obtained during our subsurface study at the above-referenced <br /> Crystal Cream and Butter Comvany site. This work had been <br /> outlined in our proposal dateC October 10, 1986. <br /> Applied GeoSystems was present on site on October 29, 1986 to <br /> perform drilling operations as proposed. Drilling was performed <br /> by Datum Exploration of Pittsburg, Catifornla. Two borings were <br /> drilled. The first boring (B-1) was drilled approximately <br /> f4fteen feet to the east of the tank excavation, as close to the <br /> e,ccavation as possible given safety limitations created by <br /> overhead power lines. Total depth or the boring was 21.5 feet, <br /> which corresponds to the first sample taken below the ground <br /> water surface. ground water was a:icountered at a depth of <br /> approximately 16.3 feet. No subjective evidence of contamination <br /> was nested, and the boring was backfilled with neat cement. <br /> The second boring, B-2, was drilled approximately six feet to the <br /> north of the excavation to a total depth of 38.5 feet, or <br /> approximately 20 feet below the ground water surface. slight to <br /> moderate odor was noted in samples taken at depths of 15 and 20 <br /> .deet. Monitoring well MW-I was installed in this boring using <br /> two inch inner diameter PVC casing. The well was constructed <br /> with thread-jointed, 0.010 inch machine-slotted casing between 37 <br /> and 7 feet, with blank casing to the ground surface. No chemical <br /> cements or solvents were used in well construction. The annular <br /> space was filled with sand from total depth to five feet below <br />
