of KMn04 mass versus time sampled to evaluate the rate of oxidant demand. The oxidant demand <br /> is reported in grams of oxidant per kilogram per day. <br /> Sample calculation: (UNITS ARE IN BOLD) <br /> 0. 152 ` {([initial conc. - mg/L] — [sample conc.- mg/L]) ' (volume in VOA - L )} / {(time - days ) ` (dry <br /> soil mass - kg)} <br /> = SOXD - MG 02/(KG SOIL ' DAY) <br /> The term 0. 152 is the conversion factor to convert equivalents of potassium permanganate to <br /> equivalents of oxygen. If chemical oxidation is required and the mass of permanganate required to <br /> treat a soil is desired, then the 0. 152 factor can be left out and the results will be reported in <br /> milligrams of potassium permanganate per kilogram soil day. <br /> I:\BP-ARC0\04 BP Valley Portfolio\BP Valley Sites\2130\Work Plan\2130 workplan 2-07.doc <br />
