<br /> 1.The volume of water treated and pounds of VOCs removed does not include the purged water that was treated on-site at the time of sampling.
<br /> 2.*average gallons per day(gpd)is calculated by dividing the'gallons treated since last recording'by the'number of days since last recording'.
<br /> 3.pg/L:micrograms per liter;mg/L:milligrams per liter
<br /> 4.lbs:pounds
<br /> 5.Calculated amount of constituent removed is estimated
<br /> 6.EW-1 is currently inactive. EI-1 was re-started on October 30,2010.
