The Qualifiers in thisreport are defined as follows:

BD E

H

,U Ul x

h Indicates that a quality control analyte recovery is outside of specified acceptance criteria.

Indicates the analyte is a surrogate compound.

Target analyte was detected in the sample as well'as the associated blank.

Flag for results below the MDC or. a flag for lowtracer recovery.

Concentration of the target analyte exceeds the'instrument calibration range.

Analytical holding.timc exceeded.

Indicates an estimated value. The.result was greater than the detection limit, but less than'the reporting limit..

Indicates the target analyte was analyzed for but not detected abovethe detection limit.

Uncertain identification for gamma spectroscopy.

Lab-specificqualifier-picase see case narrative, data summary package or contact your project manager for.details..

Sample preparation or preservation holding time exceeded.

N/A indicates that spike recovery limits do not apply wheni-sample concentraiion exceeds spike cone, by a factor of 4'or more.

• • Indicates analyteis a surrogate compound.

^ TheRclativePereent Differen6ce(RPD)ob'tinWd frommhesaniplc'duplicate (DUP)-is evaluated against the acccptence criteria when the sample is greater than five times (SX) the contract required detection limit (RL),.'In cases where.either.the.sample or duplicate value is less than 5X theRRL, a control limit of +/- the RLis used to evaluate the DUPresult.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical.method has been performed underNELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.
