chemicals used in the fraccing have contaminated water supplies since they are so deep. <br />There's no evidence that they have contaminated any water supplies. <br />f. Drilling acti<~ities' impact on eater quality. Drilling activities including ~yellpads and mud <br />pits do not typically harm water supplies. Ho« ever. «Tater that is extracted ~3°ith gas and kept <br />in oil-~~ titer separating tanks can pollute ~yater sources if the taI>Ics rupture. Benzene is <br />t~pically~ included ~yith ~~ titer and gas, and it is highl~~ toxic. This is a long-tern monitoring <br />issue. <br />g. Baseline reports should be clone now. Levorson recommends that all well o~yners in areas <br />of hea~,~~ nah~ral gas drilling monitor the saline content of water in their wells now and <br />periodically in the future. This will permit them to determine if drilling is causing saline <br />~yater to contaminate their wells. Without baseline data, it is hard to determine this. <br />h. Garfield drilling acti<~ity. There are now 4.100 operating natural gas wells in Garfield <br />County, and 2.G00 permits for additional wells were issued in 2007. There ~yere fe~3• «-ells <br />until 1999. Up to 40,000 total wells are projected in the region by 203. <br />i. Saline plumes should he in~~estigated. Levorson thililcs that additional studies should <br />determine if saline plumes are now migrating toward the Colorado Riyer. Some plumes have <br />already started. <br />9. Energy Demand Water Needs Assessment. Angie Fo~~,~ler and ,Tared Walter of URS discussed <br />progress on the Energy- Demand Water Needs Assessment Phase 1 of the study «,°ill review <br />existing data and literature, review conditional water rights, and de~-elop scenarios for ~yater <br />consumed in energy development in the Yampa-Green, White, and Lower Colorado basins. <br />a. Natural gas acti<~ities produce more water than they consume. As discussed above, this <br />produced ~yater is typically saline. It can be evaporated in ponds, reused in the process of <br />paclang well holes with mud, spra~~ed on dirt roads (many of which are new) to suppress <br />dust, to or reinjected into deep aquifers. <br />b. Water needed for oil shale production is estimated to equal l-3 banelsper barrel of oil <br />produced. <br />c. Significant additional «•ater ~i ould be required to de~•elop electricity needed for oil <br />shale production. Industry estimates that up to 7.000 MW of energy would be required: the <br />largest electricity plant today in Colorado is in Craig, and it produces 1200 MW. <br />d. The energy needs assessment hopes to deli~-er estimates of ~i•ater needed in different <br />scenarios in April. <br />111. Den~~er Metro, South Platte and Arlansas Roundtables request a meeting ~i~ith the CBRT. <br />The chairs of the Denver Metro, South Platte and Arkansas Roundtables requested in a letter <br />dated Febn~alti- 22, 2008, that the CBRT join them to discuss water conten ation. reuse, <br />agriculh~ral transfers, and new supply sources. <br />11.
