Leo M. Eisel, Ph.D., P.E. <br />• standard. This woxk included mine discharge and in-stream sampling, <br />CDPS discharge permit review, Mosquito Creek Basin TMDL review and <br />evaluation, and data analysis to suppoxt re-calculation of the zinc standard <br />based on site-specific conditions. <br />SurFace and Groundwater Modeling <br />Groundwater and Surface Water Hydrologic Analysis, EI Paso v. New Mexico <br />ProjectManager, ExpertWitness. Developed a deterministic model of monthly <br />flows and groundwater depletion and accretion to the middle and lower Rio <br />Gxande. Developed a two-dimensional groundwater model to estimate <br />depletion to river and alluvial aquifexs fzom the exportation of 250,000 acre- <br />feet per year of New Mexico groundwater to the city of El Paso. <br />Hydrologic Study of the Platte River, Lower Platte North Natural Resources <br />District and National Audubon Society, Nebraska <br />Project Manager, E4ert Witne.rs. Developed a stochastic computer model of <br />Platte River flows. Pexfoxmed groundwatex analysis to estimate xeturn flows <br />and analysis of hydrology to detexmine the effects of future groundwatex <br />depletions on surface flows. Presented expert test'tmony concerning water <br />rights applications before the Nebraska Department of Watex Resources. <br />Fiydrological Study, The Telluride Company, Telluride, Colorado <br />• Project Manager. Completed an extensive hydrologic analysis to deterinine the <br />availability of watex from on-mountain wells and the assuxance of a <br />continued supply of water from the Telluride on-mountain wells. This woxk <br />involved the use of a fuute diffexence groundwatex model as a water balance <br />tool to detexmine the adequacy of existing groundwater supplies to meet <br />future demand. <br />Groundwater Model, EI Paso Counry, Colorado <br />ger, E.xpert Witne.r.r. Developed a three-dimensional groundwater <br />Pmject Mana <br />flow model for purposes of deterinining the effect of proposed regulations <br />on groundwater resources in El Paso County. <br />Groundwater Investigations <br />Well Depletions, U.S. Department of Justice, Nebraska v. Wyoming <br />ProjectManager. Developed engineering reports concerning water rights and <br />effects of well deplerions fox North Platte River expert testimony. <br />Groundwater Analysis, The Nature Conservancy (TNC), USA <br />Project Manager. Completed uutial analysis of groundwater on property <br />purchased by TNC in eastern Coloxado on the Arikaree Rivex. The purpose <br />of the analysis is to determine those future actions TNC should take to <br />insure continued live stream through the property. <br />• <br />10 <br />C1Documents and Settingslmark.wa9ner\Local SetUngs\Temparery Internet Files\OLK17lEisel_Leo.doc
