<br /> Notes:
<br /> a =Calculated removal rate is the influent concentration times the daily vo#ume discharged
<br /> l and rounded to the nearest 1001h.
<br /> b =Cumulative removed is the sum of the calculated removal rate. l
<br /> C =Batch sample not collected.the MtBE concentration is an average of the initial
<br /> and final M1BE concentrations.
<br /> d Historical MtBE mass removal added to the 8131/04 cummulative removal.
