Attachment E-1 Contamination Measurement Methodology: Single Loads <br />REV: 03-16-18 MI <br />ATTY/AGR/2018.054/RECOLOGY OF SAN MATEO ATTACHMENT E <br />Page 7 of 14 <br /> <br />For example, the following simplified scenario involves three samples. For the purposes of this <br />example, only the weights of the component carpet are shown. <br /> <br /> Sample 1 Sample 2 Sample 3 <br />Weight (c) of carpet 5 3 4 <br />Total Sample Weight (w) 80 70 90 <br /> <br />05.0907080 <br />435 =++ <br />++=∑Carpetr <br /> <br />To find the composition estimate for the component carpet, the weights for that material are <br />added for all selected samples and divided by the total sample weights of those samples. The <br />resulting composition is 0.05, or five percent (5%). In other words, five percent (5%) of the <br />sampled material, by weight, is carpet. This finding is then projected onto the stratum being <br />examined in this step of the analysis. <br />6.2.B. - Page 168
