Analyst
Qualifiers. B - Analyte detected in the associated Method Blank, value not subtracted from result
L - Extrapolated value.Value exceeds calibration range
It - Sample analysis exceeded analytical holding time
J - Indicates an estimated value when the compound is detected, but is below the LQL
S - Spike Recovery outside accepted limits
U - Compound analyzed for but not detected
X - See case narrative
* -Value exceeded the Maximum Contamination Level (..MCL), TCLP limit, or if
compound is undetected, LQL exceeds MCL.
