Definitions
Al2: MS/MSD fail recovery, but the LCS passes criteria.
A6: Sample received past maximum recommended holding time.
A91: Sample received improperly preserved
AL: Lead and copper action level for treatment technique.
G8: Oxygen usage is less then 2 mg/L for all dilution sets. The reported value is an estimated less than value and is
calculated from the dilution using the most amount of sample.
H1: Sample was received past holding time.
M1: Matrix spike recovery is outside of acceptance limits, biased high.
M2: Matrix spike recovery is outside of acceptance limits, biased low.
MCL: US EPA Maximum Contaminant Level
mg/L: Milligrams per Liter
NAD: Normalized Absolute difference
RL: Reporting Limit
RPD: Relative Percent Difference
S1: Relative Percent Difference (RPD) outside accepted recovery limits
SMCL: US EPA Secondary Maximum Contaminant Level
