Effect on sediment yield and water quality of a nonrehabilitated surface mine in north-central Wyoming
Sediment and chemical quality of water data were collected from two adjacent drainage basins in northern Wyoming to compare hydrologic differences between an undisturbed basin and a surface-mined, virtually unrehabilitated basin. Rate of sediment accumulation in a pond in the basin that was surface mined for coal and left unrehabilitated was over 11 times greater than in a pond in the adjacent unm

Concentrations of metals in very small volumes of soil solution
A new method of sampling very small amounts of soil solution (0.3 g) shows that soil solutions contain high concentrations and unusual proportions of metals. In the soils studied, the solution is close in both metal proportions and total metal mass to what may be taken up annually by the growth of plants at the sites sampled. Composition of soil solution varies seasonally and with depth in soil. ?

Overburden chemistry and mineralogy at Hanging Woman Creek, Big Horn County, Montana, and recommendations for sampling at similar sites
Cored overburden rock of the Fort Union Formation at the Hanging Woman Creek potential coal mine site was classified in hand specimen on the basis of color and grain size into 3 types: sandstone. siltstone-plus-shale, and dark shale. The samples were analyzed for bulk chemistry and mineralogy. In general the samples of sandstone contain the lowest concentrations of elements of environmental concer
