A PERMEABLE REACTIVE BARRIER (PRB) FOR THE REMOVAL AND IMMOBILZATION OF SELENIUM IN SEEP WATER AND SHALLOW GROUNDWATER AT A PHOSPHATE MINE IN SOUTHERN IDAHO: RESULTS OF BENCH SCALE TESTING

Abstract

Abstract: A bench study was designed to determine the efficacy of a permeable reactive barrier (PRB) for removing elevated Se in groundwater and seep water at the toe of overburden storage area at a phosphate mine in Idaho. The bench testing was considered a first step in the pre-design considerations for developing an engineering and geochemical strategy for long-term water treatment options at the site.
