Abstract

As part of the Yucca Mountain Oversight program, the Nye County Nuclear Waste Repository Project Office (NWRPO) has established a groundwater monitoring program to protect groundwater resources for the residents of Nye County in Amargosa and Pahrump Valleys. This groundwater monitoring program, referred to as the Nye County Early Warning Drilling Program (NCEWDP), involves drilling a series of wells down-gradient from Yucca Mountain for long term groundwater monitoring and also to provide much needed geologic and hydrologic information in this area. A comprehensive database of aquifer parameters in the alluvial, volcanic, and carbonate aquifers down-gradient hydrogeologically of Yucca Mountain is being assembled and the degree of communication and the inter-relationships of these aquifers is under investigation. The Harry Reid Center for Environmental Studies (HRC) has been tasked to provide hydrochemical evaluations of the groundwater collected from the NCEWDP wells. The HRC collected a total of thirteen samples in May through July of 1999, eight samples in November, 1999, and sixteen samples in May 2000. These samples were analyzed for major ions, trace elements, and the oxidation states of arsenic (As), antimony (Sb), and selenium (Se). Sample collection and analysis were performed following the requirements of the University and Community College System of Nevada (UCCSN) Quality Assurance Program.
