This study quantified changes in nutrients, sediment transport, and algal biomass during normal and storm conditions in a treated acid mine drainage stream. Nitrate, sulfate, total reactive phosphorous (TRP), sediment deposition and total suspended solids (TSS) were measured during each sampling event. Biological response was measured by comparing algal biofilm biomass. Antecedent precipitation index (API) was an indicator of runoff potential. As API increased TSS increased, while chlorophyll a, conductivity, and sulfate decreased. TSS, nitrate, and sediment deposition were higher overall during storm events. TRP remained low at all sites during the sample period, suggesting phosphorous limitation.

Effects of Vegetation on Erosion in Technosols Produced from Coal Waste

Universidade Federal do Rio Grande do Sul, Brazil

The aim of this study was to evaluate soil loss by water erosion considering different technosols configurations produced from fine and coarse coal waste and an agricultural soil. All substrates were amended with sewage sludge to obtain 3% organic matter. The study considered two precipitation levels and the presence, or not, of the Medicago sativa (alfafa) and grass. Calculations were carried using the Revised Universal Soil Loss Equation. In terms of erosion control, the best configuration was attained with the mixture of coarse and fine waste. The presence of vegetation reduces in almost 100 times soil loss due rainfall.

Biodiversity Benefits Of Coal Mine Water Remediation Schemes For Bird Life

Lagoons and reedbeds are established components of mine water treatment systems for iron-rich coal mine drainage. This study coupled British Trust for Ornithology Bird Survey monitoring with habitat survey to assess the presence and usage of two UK coal mine water treatment systems by bird species. Over thirty species were documented at the two sites including four red listed, eight amber listed and eighteen green listed species (under the BTO Birds of Conservation Concern designation). There were statistically significant associations of bird group with habitat types suggesting that a mosaic of habitats at coal mine treatment systems benefits bird diversity.

Long-time Effect of Ancient Salt Production (Perm Krai, Russia)

Elena Khayrulina, Natalya Mitrakova

Perm State National Research University, Russian Federation

On the territory of the outflow of ancient brine wells in the valley of the Usolka River, soils and vegetation, transformed under the long-term impact of highly mineralized waters on the soil pore, were studied. Brines from ancient brine-lifting wells flow in streams along the soil surface and flow into the Usolka River determining its Na–Cl composition. The study area is characterized by the presence of salt-tolerant plants. Long-term influence of sodium-chloride waters on alluvial soils of the Usolka River led to the formation of a secondary gley sulfate-chloride solonchak (Gleyic Fluvic Solonchak (Loam, Salic)).

Two sets of column test have been run for the design of a passive treatment of AMD at Parys Mountain. After 5 weeks of test runs, the two DAS system sets tested promote total metal removal of Fe, Al, Zn and Cu, and high retention / removal of Mn, As, Cd, Co, Cr and Ni by adsorption/coprecipitation processes. Sulfate removal was only efficient in one of the set-up. From the incoming 2340 mg/l of sulfate, the output solution concentration was 543 mg/l. No loss of permeability has been observed during the experiments.
