In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it i s common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected).

Definitions Accuracy -The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision

-The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate

-Organic compounds that are similar in chemical composition , extraction, and chromatography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are ically related to the surrogate compound.

Surrogates are added to the sample and carried through all stages of preparation and analyses.

TIC -Tentatively Identified Compound:

Compounds detected in samples that are not target compounds , internal standards, system monitoring compounds, or surrogates.

The quality samples include a method blank, a laboratory control sample, and the matri spike/matrix spike duplicate analysis.

If a target parameter is outside the method limits , every sample that is effected is flagged w ith the appropriate qualifier in Appendix B of the analytic report. Method Blank -an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis.

Concentrations o target analytes above the reporting limit in the method blank ar qualified with the 8" qualifier.

Laboratory Control Sample -is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control".

If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a J4 qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate

-is two aliquots of an environmental sample that is spiked with known concentrations of target analytes.

The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a JS" or a "J6". The relative percent difference

('RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated.

If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.
