[ V 1111111111111111111 AL• CONSTRUCTION • COMPLIANCE <br /> 999 <br /> RFC& <br /> AUG p I ft <br /> July 31,2000 <br /> Mr. Roger Doak <br /> Colorado Department of Public Health and Environment (CDPH&E) <br /> Hazardous Materials and Waste Management Division <br /> 4300 Cherry Creek Drive South <br /> Denver,CO 80246-1530 <br /> RE: Additional Analytical Data <br /> Varra Coal Ash Proposal <br /> Weld County,Colorado <br /> CGRS No. 1-135-2755 <br /> Dear Mr. Doak: <br /> I have attached additional analytical data generated for the Varra project. The USGS did <br /> comparative testing of selected elements from pore volumes one, two and four. The analytical <br /> technique was ICP-MS. I have hand-written the comparisons on the USGS spread sheet. A review <br /> of the data show that the comparison of analytical data generated by Barringer and USGS are good <br /> with the exception of molybdenum. The concentrations of molybdenum were an order of magnitude <br /> less by the confirmation of ICP-MS. <br /> Also provided are analytical results of samples obtained from pore volume 29. A review of the data <br /> shows that drinking water standards were not exceeded with the exception of sulfate, which <br /> approximated levels measured in the leaching medium. <br /> If you have any questions regarding this information or require further information, please contact <br /> me at(800)288-2657. <br /> Sincerely, <br /> C N <br /> Job Ad Pkk <br /> .G. <br /> inc aVHydrPn ogeolo gist <br /> Attachments <br /> cc: Mr. Chris Varra—Varra Companies <br /> Mr. Trevor Jiricek—Weld County Health Department <br /> Ms.Christina Kaminikar-Colorado Division of Minerals and Geology <br /> N <br /> P.O.
