Acid Mine Drainage at the Nickel Rim Mine Tailings
The diffusion of gas-phase O2 into the unsaturated zone has caused the oxidation of sulfide minerals (pricipally pyrrhotite) in the shallow tailings. Pore water within the impoundment ... 10 piezometers each, in and around the tailings impoundment. Detailed measurements of pore water chemistry, pore gas composition, tailings mineralogy and hydraulic parameters were made at these nests. Geochemical ...

Evaluation of Low Sulphur Tailings for Reducing Acid Mine Drainage
The lysimeters were monitored for various parameters including pore-water composition, O2 and CO2 pore-gas concentrations, microbiology and bulk physical properties of the tailings. Results To ... until 4.3 years. Pore-gas oxygen concentrations were depleted in the upper 20 cm of the MT and TT lysimeters in 1993, however, complete gas-phase oygen depletion was not ...

Radon: Environmental Health in Minnesota
Upper Midwest contains widespread uranium and radium. These minerals continuously break down to release radon gas. Therefore, Minnesota's geology provides an ongoing supply of radon. In addition, a large ... crawl spaces, unsealed sumps, cracks in slab-on-grade floors, utility penetrations, and the tiny pore spaces in concrete block walls. A basement, of course, provides a large surface area that ...
