Analyst Approved
Qualifiers: B - Analyte detected in the associated Method Blank, value not subtracted from result Definitions: NA - Not Applicable
L•' - Extrapolated value.Value exceeds calibration range LQL - Lower Quantitation Limit
1-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
ti - 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.
