“…Although lasting negative effects from mining can occur in some regions under certain types of mining, such as mountaintop removal in the Appalachian Mountains [9][10][11], research in east Texas has generally found no lasting negative effects for soil and water quality [12][13][14][15][16]. This may be due in part to the fact that the topography is relatively level on the upper Coastal Plain, and the parent materials are less rocky than in other regions.…”

Surface lignite coal mines in east Texas are commonly reforested using loblolly pine (Pinus taeda L.) following mining and reclamation activities. Due to the nature of such an extreme disturbance, altered growth patterns, growth rates, and productivity could be expected. We destructively sampled above-and belowground tissue to develop prediction equations specific to these sites. These prediction equations differed statistically from those found in the literature regarding unmined land. At the stand level, biomass and volume productivity appeared similar with young stands on reclaimed mineland performing slightly poorer than similarly managed unmined sites. Allometric partitioning of above-and belowground biomass differed statistically from the unmined allometric model previously studied. The allometric pattern on reclaimed mineland indicated greater partitioning of biomass belowground for young stands of low quadratic mean diameter relative to unmined stands. Older stands on reclaimed mineland exhibited no allometric partitioning differences from unmined stands, indicating the normal allometric pattern is resumed for stands greater than 10 years of age.

“…An estimated 10 000 km of streams in the Appalachian coal mining region of the United States are adversely impacted by acidic mine drainage (AMD) that emanates from abandoned and operating coalmines (Herlihy et al, 1990). The AMD arises when metal sulfides (primarily coal deposit-associated pyrite) come in contact with oxygenated water resulting in sulfuric acid production by the biogeochemical oxidation of reduced sulfur species (Baker and Banfield, 2003).…”

Characterization of Fe(II) oxidizing bacterial activities and communities at two acidic Appalachian coalmine drainage-impacted sites

We characterized the microbiologically mediated oxidative precipitation of Fe(II) from coalminederived acidic mine drainage (AMD) along flow-paths at two sites in northern Pennsylvania. At the Gum Boot site, dissolved Fe(II) was efficiently removed from AMD whereas minimal Fe(II) removal occurred at the Fridays-2 site. Neither site received human intervention to treat the AMD. Culturable Fe(II) oxidizing bacteria were most abundant at sampling locations along the AMD flow path corresponding to greatest Fe(II) removal and where overlying water contained abundant dissolved O 2 . Rates of Fe(II) oxidation determined in laboratory-based sediment incubations were also greatest at these sampling locations. Ribosomal RNA intergenic spacer analysis and sequencing of partial 16S rRNA genes recovered from sediment bacterial communities revealed similarities among populations at points receiving regular inputs of Fe(II)-rich AMD and provided evidence for the presence of bacterial lineages capable of Fe(II) oxidation. A notable difference between bacterial communities at the two sites was the abundance of Chloroflexi-affiliated 16S rRNA gene sequences in clone libraries derived from the Gum Boot sediments. Our results suggest that inexpensive and reliable AMD treatment strategies can be implemented by mimicking the conditions present at the Gum Boot field site.

“…Because, it is known that streams in coal mining areas carry highly acidic water with high sulphate content 1,28 . Study on Wilge River -a tributary of Vaal River in South Africa reported a similar situation where acidic water drained from the old coal mining was found to have significantly high sulphate content.…”

Seasonal Variation in Water Quality of Lukha River, Meghalaya, India

Lukha River (Wah Lukha) is one of the major rivers of Meghalaya situated in the southern part of East Jaintia Hills District. Activities such as mining of coal and limestone, manufacturing of cement, deforestation etc. have been taking place in the catchment area of the river leading to changes in water quality. This is evident from the deep blue appearance of water of Lukha River during winter months for the last 7-8 years. Till date no convincing and conclusive reason has been given for this annual change in physical appearance. To get insight, we studied the physico-chemical water quality parameters of this river in different seasons and found that the water quality has started deteriorating due to activities occurring in the catchment area. Based on Canadian Council of Ministers of the Environment-Water Quality Index (CCME-WQI) the water of the river at some locations was found of 'poor' quality.
