For nonradiological analyses, if the analyte is not detected, the sample-specific estimated quantitation limit (EQL) is entered into the result field and is reported with a less than [e]sign. The EQL is defined as the lowest concentration that can be achieved reliably within specified limits of precision and accuracy during routine laboratory operating conditions. The sample-specific EQL is modified for sample concentration or dilution or unusual aliquot size that affects analytical sensitivity. Holding Times Standard analytical methods include a limit, called holding time, on the maximum elapsed time between sample collection and extraction or analysis by the laboratory. In the data tables, a large bullet (-) in the H (holding time) column indicates that holding time was exceeded. Analyses performed beyond holding times may not yield valid results. The South Carolina Department of Health and Environmental Control (SCDHEC) allows only minutes to elapse between sampling and analysis for ph. Thus, only field ph measurements can meet the holding time criterion; laboratory ph analyses always will exceed it. The laboratory procedure used for the determination of specific conductance allows one day to elapse between sampling and analysis. Thus, laboratory specific conductance measurements may exceed the holding time criterion. Data Rounding A constituent result in the analytical results tables that is not marked in the STcolumn but appears to equal an Appendix A standard is below the standard in the database. alues stored in the database contain more significant digits than the reported results. Apparent discrepancies in the tables are due to the rounding of reported results. Data Qualification The contract laboratories submit sample- or batch-specific quality assurance/quality control information either at the same time as analytical results or in a quarterly summary. Properly defined and used data modifiers (also referred to as qualifiers) can be a key component in assessing data usability. Modifiers designed by EPDIEMS and provided to the primary laboratories are defined below. These modifiers appear in the data tables under the column Mod. All lettered modifiers except are based on EPA's STORET codes. 2 First and Second Quarters 997

9 WSRC-TR-97-2 Modifiers Data are not qualified. Numbers should be interpreted exactly as reported. The detected result is between the sample-specific EQL and the method detection limit. The value in the result field is the instrument reading, not the sample quantitation limit. Always used with the result qualifier U. alue is estimated because quantitation in the sample or in associated quality control samples did not meet specifications. alue is off-scale high. The actual value is not known but is known to be greater than the value shown. Presence of the analyte is verified but not quantified. Result was rejected because performance requirements in the sample analysis or associated quality control analyses were not met. Analyte was not detected; if present, it was below the criteria for detection. Material analyzed for but not detected. Analytical result reported is less than the sample quantitation limit. Analyte was detected in an associated method blank. Result was obtained from an unpreserved or improperly preserved sample. Data may not be accurate. Result may be an underestimation of the true value due to analytical bias. Result may be an overestimation of the true value due to analytical bias. The associated result may be of poor precision (high variability) due to analytical bias. (Blank) E I L M R T U Y 2 3 Note: These are only some of the qualifiers present in the database. All modifiers associated with the data are published in the result tables of EPD/EMS quarterly groundwater monitoring reports, the official repository of the data. 3 First and Second Quarters 997

32 WSRC-TR-97-2 Flagging Criteria Beginning first quarter 992, flagging criteria were established for all constituents analyzed as part of the EPD/EMS Groundwater Monitoring Program. Only the flagging criteria for environmental screening analyses are used to trigger scheduling for designated wells in the environmental screening program, while all flagging criteria in Table B- are used to flag constituents in the analytical results tables. The following rules are used in determining flagging criteria and scheduling sampling: Flag : Analysis for a constituent below Flag is classified as Flag. Constituents classified as Flag in each well series will be scheduled for analyses only by custodian request or as part of the triennial environmental screening program for wells designated as environmental screening wells. Flag : The Flag criterion for a constituent equals half of the EPA primary drinking water standard (PDWS), the EPA proposed PDWS, or the EPA secondary drinking water standard (SDWS) for that constituent. If a constituent does not have an EPA drinking water standard, the Flag criterion equals times a recently published 9th percentile detection limit obtained by one of the primary laboratories. If a constituent exceeds Flag in a monitoring well series, environmental screening wells in that series are sampled and analyzed for that constituent once a year. If a constituent falls below Flag for three consecutive sampling episodes, the well s flag is reduced from Flag status to Flag status and follows the rules for Flag. Flag 2: The Flag 2 criterion for a constituent equals the EPA PDWS, the EPA proposed PDWS, or the EPA SDWS for that constituent. If a constituent does not have a drinking water standard, the Flag 2 criterion equals times a recently published 9th percentile detection limit obtained by one of the primary laboratories. If a constituent exceeds Flag 2 in a monitoring well series, environmental screening wells in that series are sampled and analyzed for that constituent once a year. If a constituent falls below Flag 2 for three consecutive sampling episodes, the well s flag is reduced from Flag 2 status to Flag or Flag status and follows the rules for the lower flag. The following constituents are exceptions to the flagging rules: Specific conductance and ph, which are indicator parameters, have flagging criteria but do not trigger the scheduling mechanism. s are set for alkalinity, -day biochemical oxygen demand, calcium, carbonate, chemical oxygen demand, magnesium, potassium, silica, sodium, total dissolved solids, total phosphates (as P), and total phosphorous because they are indicator parameters or major cations. Analyses for these constituents are conducted as part of the triennial environmental screening program or by special request. Aesthetic analyses such as color, odor, corrosivity, turbidity, and surfactants are not assigned flagging criteria but are analyzed by special request. Common laboratory contaminants and cleaners including phthalates, dichloromethane, ketones, and toluene are not assigned flagging criteria unless they have a PDWS. These constituents are analyzed by special request. Table B-.
