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
II - Sample analysis exceeded analytical holding time Surr - Surrogate
1 - Indicates an estimated value when the compound is detected, but is below the LQL
S - Spike Recovery outside accepted limits
I I -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. Print Date: 11/2/2009
