Project No. E6576.001 Additional Groundwater Sampling/W. Clover IYd 22 March 1995 I <br /> { <br /> I <br /> MASS QUANTIFICATION CALCULATIONS <br /> r <br /> The mass quantification of diesel in the "contaminated" stockpile is shown (see <br /> { <br /> calculation) to be approximately 0.71 gallons (5.09 lbs) of diesel in entireit. It is the p <br /> estimated that there may remain only approximately 0.11 gallon (0.80 lbs) of diesel in the <br /> remaining below-groundwater trim and sluff material. <br /> L <br /> i <br /> 1 Mass Quantity Calculation <br /> L <br /> i <br /> r Clover Road, Tracy <br /> Quantity in "contaminated" stockpile (200 yards) <br /> Estimated 80% sandy backfill and 20% native clay <br /> Sand samples 1A: 2,800 grams gross <br /> Lightly packed as 113 in stockpile: 3,011 grains gross <br /> Average 1: 2,955 grams gross <br /> 1•� Container Tare: - 162 grams <br /> 2,793 grams net <br /> Water: 2,098 grams net <br /> Specific Gravity: 1.330 <br /> p Y <br /> I <br /> Clay sample 2A: 3,345 grams gross <br /> p <br /> From stockpile 213: 3,498 grams gross <br /> Average 2: 3,422 gross <br /> Container Tare: -162 ?rams <br /> 3,260 grams net <br /> CWater: 2,098 grams net <br /> Specific Gravity: 1.552 <br /> L <br /> Weight of Sand <br /> r 200 x 62.4 #/cf x 27 cf/cy x 80% x 1.330: 358,525# <br /> L <br /> Weight of Clay <br /> 200 x 62.4#/cf x 27 cf/cv x 20% x 1.552: 104,592 <br /> TOTAL WEIGHT OF STOCKPILE: 452,017# <br /> r TERRASEARCH, INC.
