Analyst Approved
Qualifiers: B - Analyte detected in the associated Method Blank, value not subtracted from result Definitions: NA - Not Applicable
E - Extrapolated value. Value exceeds calibration range LQL - Lower Quantitation Limit
I I - Sample analysis exceeded analytical holding time Surr - Surrogate
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
Y - See case narrative
* -Value exceeded the Maximum Contamination Level (MCL), TCLP limit, or if
compound is undetected, LQL exceeds MCL. Print Date: 7/24108
