Abstract
| Flow Contribution and Water Quality with Depth in a Test Hole and Public-supply Wells: Implications for Arsenic Remediation through Well Modification, Norman, Oklahoma, 2003-2006 (PDF) (70 pp, 6.5 MB) (EPA/600/R-09/036) April 2009 Appendix (PDF) (77 pp, 5.2 MB)  This publication has been produced as part of the Laboratory's strategic long-term research plan. It is published and made available by EPA's Office of Research and Development (ORD) to assist the user community and to link researchers with their clients. Arsenic is a common ground-water contaminant at hazardous waste sites and a widespread issue confronting many drinking water supplies in the U.S. The purpose of this document is to provide a hydrologic and geochemical basis for assessing the potential for restoring existing water supply wells impacted by elevated concentrations of arsenic from natural sources. This report will fill a need for a readily available source of information for water supply managers and others who are faced with this problem. The information provided in this document will be of use to stakeholders such as state and local environmental agencies, public water supply managers, Native American tribes, consultants, contractors, and other interested parties.
