  • Uranium Mining and Milling Wastes An Introduction

    May 18, 20110183;32;Considering the actual period of time the hazards from uranium mining and milling wastes persist, these regulations are of course only a compromise, but they are a first step, at least. Regulations for the protection of groundwater were not included in the initial legislation; they were only promulgated in January 1995.
