Cream and Butter Co. , <br /> ' 404 W. Fremont St . , Stockton, California. <br /> Dear Ms. Cotulla: <br /> At the request of RAMCON, 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 Company site. This work had been <br /> outlined in our proposal. dated 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, California. Two borings were <br /> drilled. The first boring (B-1) was drilled approximately <br /> ' fifteen feet to the east of the tank excavation, as close to the <br /> excavation as possible given safety limitations created by <br /> overhead power lines. Total depth of the boring was 21 . 5 feet, <br /> ' which corresponds to the first sample taken below the ground <br /> water surface. Ground water was encountered at a depth of <br /> approximately 16. 3 feet. No subjective evidence of contamination <br /> was noted, and the boring was backfilled with neat cement. <br /> The second boring, B-2, was drilled a y <br /> roximatel six <br /> north of the excavation to a total depth of 38. 5feet,fort to the <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 /> feet. Monitoring well MW--1 was installed in this boring using <br /> ' two inch inner diameter PVC casing. The well was constructed <br /> with thread-jointed, 0. 020 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 />
