with now saline groundwater, which has increased <br />SC and SAR as a result of dissolving the naturally <br />occurring salts in the soil, resulting in an increase <br />in the SC and SAR of the in- stream water as it flows <br />downstream. As is common in the PRB, the volume of <br />produced waters decreases with time, causing the dis- <br />charge in the channel to decrease. Associated with the <br />decreased discharge is a lowering of the water depth in <br />the channel which causes a reversal of hydraulic gradi- <br />ent. When this situation occurs, there is less mixing <br />of discharge water with groundwater and the SC and <br />SAR in- stream increases further. <br />During our investigation, we noted that significant salt <br />crusts had formed on the near - channel soils for the <br />study site that had been in operation for 4 years. For <br />the site with two years of operation, there was only mi- <br />nor salt crust. For the site that came on -line during our <br />study, we observed that salt crusts formed in several <br />locations once the near - channel soils became saturated. <br />Our findings show that changes in water quality can <br />happen on a relatively short time frame as the dis- <br />charge water interacts with the salts in the soil. During <br />the first couple of years as the discharge of produced <br />waters stays relatively constant, the major impact is the <br />large increase of SC and SAR in the saturated near - <br />channel soils with a minor increase in these parameters <br />as the discharge water moves downstream. As the dis- <br />charge of produced waters decreases, there is a large <br />increase in SC and SAR values as the water moves <br />downstream due to the reversed hydraulic gradient. <br />Another major impact is that once discharge ceases, <br />the water in the once saturated near - channel soils will <br />evaporate, leaving behind a significant amount of salt <br />crust on the surface of the soils. <br />Alternatives for CBM water disposal include rein- <br />jection, mixing with other salts to decrease SAR, or <br />evaporation. However, with the presence of salts in <br />the soils coupled with the and climate, these alterna- <br />tives may be for naught. <br />Please feel free to contact us with any ques- <br />tions. <br />Acknowledgments <br />Funding for this study and thesis sup- <br />port for Andy Neuhart was provided by <br />USEPA under contract <br />CP- 98864201 -0, Denver, CO. <br />Colorado Foundation for Water <br />Education Hires New Director <br />DENVER -The Colorado Foundation for Wa- <br />ter Education is pleased to announce that it has <br />named Don Glaser as its new Executive Director <br />for the statewide non - advocacy water organiza- <br />tion. <br />Glaser comes to the Foundation from the Douglas <br />Land Conservancy, where he also served as Execu- <br />tive Director. He has also been employed as a <br />senior manager for the National Fish and Wildlife <br />Foundation, and as a private consultant. In the <br />mid- 1990s, he was appointed executive director <br />of the Western Water Policy Review Advisory <br />Commission. The commission was charged with <br />reviewing the status of western water resources, <br />and addressing potential changes to federal policy. <br />Glaser will begin work with the Foundation June <br />1. He will work in transition with the existing <br />Executive Director, Karla Brown, who will resign <br />on June 19. <br />The Colorado Foundation for Water Education <br />was created in 2002 to promote better understand- <br />ing of water resources through education and <br />information. It publishes Headwaters magazine, <br />guides tours around the state, and offers leader- <br />ship trainings, conferences, and publications <br />on topics such as water law, water quality, and <br />conservation. The Foundation is the only non -ad- <br />vocacy water education organization in state. <br />For more information call (303)377 -4433 or visit the <br />foundation web site at www.cfwe.org. <br />Annual Meeting <br />of <br />International Soil and Water Conservation Society <br />July 22 -26, 2006 <br />Keystone, Colorado <br />For more information or to register, go to <br />http://www.swcs.org/en/swcs-intemational-conferences/ <br />
