21800 NORTH RIPON ROAD AND RIVER ROAD, RIPON, CA. <br /> SAMPLING REPORT <br /> MARCH 25, 1994 <br /> On March 24, 1994, Eleanor Ratliff, Senior Registered Environmental Health Specialist <br /> (REHS), and Michael Kith, Senior REHS, met with Mark Brock and Pat Wheeler of FGL, <br /> an environmental laboratory, at the above referenced site to obtain soil samples. Soil <br /> sampling was performed as a result of an ammonia nitrate spill which occurred on <br /> February 14, 1994. <br /> The location of the spill was on the southeast corner of North Ripon Road and River Road <br /> in Ripon, CA. The area had been previously excavated to remove top soil contaminated <br /> with high amounts of the fertilizer. The possibility of residual contamination left in place <br /> compelled this investigation. <br /> Nine soil samples were taken by FGL field representatives, Mark Brock and Pat Wheeler. <br /> The samples were obtained by advancing a "Ground Hog Earth Auger" with a solid stem, <br /> 30" bit, to a depth of three feet. A six-inch brass tube was then used to collect an <br /> undisturbed sample from the native soil. Sample #'s 1-6 were drilled very near the <br /> roadside at a 45 degree angle to collect a sample beneath the road which was lateral to the <br /> spill. Sample #7 and #9 were drilled at a 90 degree angle to the ground to a depth of <br /> three and four feet, respectively. Sample #8 was drilled south of the spill area along North <br /> Ripon Road at a depth of three feet. This sample will serve as a representative background <br /> sample. <br /> All nine samples were immediately sealed with teflon, capped, labeled, and placed in a <br /> chilled cooler for transport, under chain of custody, to FGL, a California State Certified <br /> Laboratory. The samples are to be analyzed for ammonia nitrate and nitrate. <br /> During drilling and sampling, careful measurements were taken to insure that <br /> representative locations were chosen. A map was drawn with these locations noted. <br /> Photographs were taken using reference points to document the sampling locations. (See <br /> map and photos enclosed.) <br /> A slight ammonia odor was detected from the cuttings of borehole #4 and #6. The <br /> ammonia odor quickly dissipated. <br /> Report prepared by: Eleanor Ratliff, Senior REHS <br /> March 25, 1994 <br />
