#	   E        Detected. Concentration is estimated. Estimated concentration may result from
#                   any of the following reasons:
#                   1. The compound is characterized as a "poor performer" in the method on the 
#                   basis of laboratory QC samples. In general compounds with less than 60 %
#                   recovery, greater than 120 % recovery, or greater than 25 % relative standard
#                   deviation of recovery are considered poor performers. All detections of
#                   these compounds are remarked E.
#                   2. The compound was detected at a concentration less than the reporting level
#                   or less than the lowest calibration standard.
#                   3. The sample was diluted to bring the concentration into the calibration range.
