III. TYPE AND QUANTITY OF INJECTED FLUIDS <br />The fluid to be injected will consist of groundwater pumped from the Upper Fox Hill <br />Formation "A" Sands. Approximately ## gallons of groundwater from the Fox Hills aquifer will <br />be produced during the pump test. The water will be stored in a steam-cleaned steel tank. <br />Nothing will be added to the produced groundwater before reinjection. Powertech will sample <br />the stored groundwater and have it analyzed before reinjection occurs. <br />The groundwater produced from the Upper Fox Hills Formation contains concentrations <br />of uranium and radium above the primary drinking water standards, also called the Maximum <br />Contaminant Limits or MCLs. The Upper Fox Hills Formation groundwater also contains <br />concentrations of iron above the Region 8 permit limit. The Laramie Formation groundwater <br />does not contain uranium and radium above the MCLs and iron above the Region 8 permit limit. <br />Water quality information for groundwater sampled in both formations is presented in Table 1. <br />Table 1: Permit Limits and Approved Analytical Methods for Total Metals <br />Parameter Name Concentration <br />in Laramie <br />( /I Concentration <br />in fox Hills <br />/L Regulatory <br />Limit <br />( /L Standard Type* <br />Antimony 1 66 6 MCL <br />Arsenic 3 ND 10 MCL <br />Barium ND ND 2,000 MCL <br />Beryllium ND ND 4 MCL <br />Boron 200 100 1,400 HA-Lifetime <br />Cadmium ND ND 5 MCL <br />Chromium(total) ND ND 100 MCL <br />Copper 10 20 1,300 MCL-TT <br />Iron 250 13,000 5,000 Region 8 <br />Permit Limit <br />Lead ND ND 15 MCL-TT <br />Manganese 150 220 800 Region 8 <br />Permit Limit <br />Mercury <br />(inorganic) ND ND 2 MCL <br />Molybdenum ND ND 40 HA-Lifetime <br />Nickel ND ND 100 HA-Lifetime <br />Selenium ND 2 50 MCL <br />Silver ND ND 100 HA-Lifetime <br />Strontium 2,900 1,500 4,000 HA-Lifetime <br />Thallium ND ND 2 MCL <br />Uranium 11.2 250 30 MCL <br />Zinc 80 30 2,000 HA-Lifetime <br />Statement of Basis <br />Powertech (USA), Incorporated. <br />UIC Class V Permit # C051237-08412 <br />Page 1 of 4 <br />Appendix 2
