Abstract |
Sludge management is an escalating concern as the inventory of sludge continues to grow through perpetual “pump and treat” of acidic waters at mine sites. Current sludge management practices, in general, are ad hoc and frequently do not adress long-term storage, and in some cases, long-term stability. While a variety of sludge disposal practices have been applied, many have not been fully investigated and monitoring data on the performance of these technologies is limited and not readily available. This paper discusses options for treatment sludge management including conventionale disposal technologies and options for reclamation of sludge areas. |

acid mine drainage Beaver Creek check dam leach beds leaching metal sequestration mine water leaching procedure open limestone channel steel slag West Virginia |

Abstract |
Steel slag from the Waylite steel-making plant in Bethlehem, Pennsylvania was leached with acidic mine drainage (AMD) of a known quality using an established laboratory procedure. Leaching continued for 60 cycles and leachates were collected after each cycle. Results indicated that the slag was very effective at neutralizing acidity. The AMD/slag leachates contained higher average concentrations of Ba, V, Mn, Cr, As, Ag, and Se and lower average concentrations of Sb, Fe, Zn, Be, Cd, Tl, Ni, Al, Cu, and Pb than the untreated AMD. Based on these tests, slag leach beds were constructed at the abandoned McCarty mine site in Preston County, West Virginia. The leach beds were constructed as slag check dams below limestone-lined settling basins. Acid water was captured in limestone channels and directed into basins to leach through the slag dams and discharge into a tributary of Beaver Creek. Since installation in October 2000, the system has been consistently producing net alkaline, pH 9 water. The treated water is still net alkaline and has a neutral pH after it encounters several other acidic seeps downstream. |

Contamination Czech Republic groundwater in situ leaching remediation |
|
| |
Abstract |
An area of the Czech Republic in the northeastern part of the Ceská Lípa district has been affected by “in situ” chemical mining of uranium. The risks associated with the contaminants have been assessed and a complex groundwater remediation project has been generated. The remediation alternatives for both the Cenomanian and Turonian aquifers are presented, relative to time requirements, economics, ecological considerations and the elimination of unacceptable risks for the population and environment. Finally, the present progress of remediation and a concept of what is necessary to complete remediation are presented. |
