Mr. Howard Hold August 16, 2004 Page 4 be followed. All samples will be placed in ice chests and kept at 4 degrees Centigrade until analyzed. Samples will be delivered to the laboratory the same day they are collected. The constituents to be analyzed are: Field Paranivers PH Specific Conductance Temperature Turbidity Dissolved Oxygen Redox Monitoring Parvuneteis Total Dissolved Solids Total Hardness Aluminum Bicarbonate Calcium Chloride Magnesium Nitrate Potassium Sodium Sulfate Evaluation Monitoring Report Per the schedule specified in the July 15, 2004 tentative revised WDRs, an updated report characterizing the impact to ground-water quality in the shallow and deep zones in the vicinity of the ponds will be submitted by October 8,2004. This report will include the as- built construction of the new monitoring facilities and the results of baseline sampling along with updated isocontours of the areal and vertical extent of elevated chloride and total dissolved solids in ground water. The wellheads will be surveyed and a round of ground- water level measurements will be made in all network monitoring wells(new and existing). The semi-annual ground-water sampling event will be coordinated in conjunction with the sampling of the new facilities to provide ground-water level and quality data at a similar time period for purposes of the updated analysis of site conditions. The report will also include, as necessary, recommendations for another"phase"of monitoring well installation if needed to satisfy the objectives of complete characterization of saline water impacts, particularly in the shallow zone. The report will also describe the wells that will be included in the corrective action monitoring network and program. Schedule In order to comply with the October 8,2004 deadline for submittal of the evaluation monitoring report,construction of the new monitoring facilities is tentatively scheduled to 10 1w
