NOTES:
Topo map revised 1998, 2000, 2004. Topo with P/S landfill andborrow area revised 2000. (Foster-Wheeler).
Zone 1 boundary (green) is approximate and includes the area withinthe facility boundary.
** Sampling location was not analyzed for explosives by EPAMethod 8330, but several explosive compounds were analyzed for byEPA 8270.
The widths of the clay barriers, PSCT, and PCT trenches are exaggerated for presentation purposes.
Bold values indicate exceedences of MCL/PRGs.
ND Not detected, but sampled and analyzedNR Not sampled/analyzed due to lack of water recovered from sampling location.NS Not sampled
Laboratory and Validation Qualifiers:
"D" The sample or sample extract was diluted prior to analysis due to highlevels of target analytes or matrix interferences.
"B" The analyte was detected in an associated blank sample. "J" The analyte was positively identified; the associated numerical value is the
approximate concentration of the analyte in the sample. For the inorganicmethods, a "+" or "-" may be added to indicate high or low bias.
"N" The analysis indicates the presence of an anlyte for which there ispresumptive evidence to make a tentative identification.
"NJ" The analysis indicates the presence of an analyte that has been"tentatively identified" and the associated value represents anapproximate concentration.
"U" Compound was analyzed, but not detected above the listed samplequantitation limit.
"UJ" The analyte was not detected above the reported sample quantitation limit.However, the reported quantitation limit is an estimate.
"R" The result is rejected due to a serious deficiency in the analysis orassociated quality control analysis.
"*" Indicates that the qualifier was applied in response to a Level IV review finding.
