0 Alternative Daily Cover - Moisture Variation Discussion <br />The moisture content of greenwaste ADC typically varies from season to season <br />along with changes in feedstock. Other factors influencing the moisture of <br />greenwaste ADC include the length of time the feedstock or shredded material sits <br />in stockpiles (inadvertent composting), and how many times the material is turned <br />over in the course of processing and handling. TASW material stockpiled at Forward <br />Landfill during the test appeared to be fairly homogeneous if taken as a large <br />population, but samples of this material varied significantly in composition from one <br />to the other. The varying amounts of absorbent vs. impervious materials present in <br />testable quantities (what would fit in a standard laboratory oven) split from the larger <br />bulk samples collected make the moisture content testing results more variable. <br />To provide information for future reference, a sample of both greenwaste and TASW <br />was collected from the stockpile and tested for moisture content. The test used, <br />ASTM method D2216, expresses results as a percentage of the sample's dry solid <br />material weight. For example: a sample with a wet weight of 100 grams, found to <br />have a 25% moisture content, would be made up of 80 grams dry solid material and <br />20 grams water (Appendix B). <br />Based on the results of ASTM D2216 the moisture content of the shredded <br />greenwaste was 26.3% moisture. <br />Based on the results of ASTM D2216 the moisture content of the shredded TASW <br />was 23.6% moisture. <br />
