The MDC is affected by counting time, sample volume, TDS <br />concentration, and instrument background. <br />After five quarters of sample data have been collected from the compliance wells, the <br />sampling parameter list and sampling frequency may be reduced in consultation with <br />DRMS. <br />The quarterly groundwater monitoring data would be submitted to DRMS within 30 <br />days of receiving the laboratory data reports and an annual report would be provided <br />to DRMS that compiles the groundwater quality data, evaluates groundwater quality <br />trends, and compares the data to the compliance limit. <br />11-3 <br />CADocuments and Settings\c odW rd.DMC\Desktop\Current TO DO\Sundays\FINAL DRMS Report RTCv2 - EPP Sunday Mines.doc
