“…Following mine closure, the tailings are disposed onto surrounding soils, leading to their exposure to environmental factors. Metal release from the tailings may lead to acid mine drainage (AMD), thus impacting soil and aquatic environments (Salomons 1995;Passariello et al 2002;Mian and Yanful 2003). Several studies have been undertaken on the impact of mining activity on soils, waters, sediments, and plants.…”

“…Several studies have been undertaken on the impact of mining activity on soils, waters, sediments, and plants. They generally show that the most widespread phenomenon in these sites is acid mine drainage which is due to the oxidation of metal sulfides (e.g., pyrite (FeS 2 )), leading to the acidification of the drainage water (Salomons 1995;Bell et al 2001;Mian and Yanful 2003;Baker and Banfield 2003;El Gharmali et al 2004;Lee et al 2005;Boularbah et al 2006a, b).…”

The aim of the present work is the assessment of metal toxicity in runoff, in their contaminated soils and in the groundwater sampled from two mining areas in the region of Marrakech using a microbial bioassay MetPLATE. This bioassay is based on the specific inhibition of the beta-galactosidase enzyme of a mutant strain of Escherichia coli, by the metallic pollutants. The stream waters from all sampling stations in the two mines were all very toxic and displayed percent enzyme inhibition exceeding 87% except SWA4 and SWB1 stations in mine C. Their high concentrations of copper (Cu) and zinc (Zn) confirm the acute toxicity shown by MetPLATE. The pH of stream waters from mine B and C varied between 2.1 and 6.2 and was probably responsible for metal mobilization, suggesting a problem of acid mine drainage in these mining areas. The bioassay MetPLATE was also applied to mine tailings and to soils contaminated by the acidic waters. The results show that the high toxicity of these soils and tailings was mainly due to the relatively concentration of soluble Zn and Cu. The use of MetPLATE in groundwater toxicity testing shows that, most of the samples exhibited low metal toxicity (2.7-45.5% inhibition) except GW3 of the mine B (95.3% inhibition during the wet season and 82.9% inhibition during the dry season). This high toxicity is attributed to the higher than usual concentrations of Cu (189 microg Cu l(-1)) and Zn (1505 microg Zn l(-1)). These results show the potential risk of the contamination of different ecosystems situated to the vicinity of these two metalliferous sites. The general trend observed was an increase in metal toxicity measured by the MetPLATE with increasing total and mobile metal concentrations in the studied matrices. Therefore, the MetPLATE bioassay is a reliable and fast bioassay to estimate the metals toxicity in the aquatic and solids samples.

An electrical resistivity survey was completed at the Landusky mine. The survey consisted of 15 lines on the surface of the reclaimed Suprise pit, Queen Rose pit, and the region immediately south of Swift Gulch. Additionally, wells and seeps were used by energizing electrodes in direct contact with ground water to increase the sensitivity of the resistivity method at depth. The survey was conducted to locate potential acid rock drainage pathways that are contaminating Swift Gulch. The results showed that the lowest resistivity values were coincident with the Queen Rose pit. Furthermore, the low resistivity feature appeared to trend northeast along a known fault, consistent with the geologic understanding of the site. A scatter plot of resistivity values versus total dissolved solids (TDS) showed a strong correlation (R 2 = 0.85). A linear regression model suggests TDS at the lowest resistivity region to be approximately 2.5 times greater than that measured in ground water wells.

“…Resuspension models, however, sometimes fail to predict resuspension with accurate precision, and several studies point out the need for further research on the processes involved (Mian and Yanful, 2003;Banas et al, 2005). Moreover, the internal contribution of sediment is still regarded as the main uncertainty in predicting the concentrations of suspended matter in lakes (Malmaeus and Håkanson, 2003).…”

The role of non-prevailing wind direction on resuspension and redistribution of sediments in a shallow lake

Sediment resuspension can significantly affect the light climate and internal nutrient loading in shallow lakes. To predict wind-induced resuspension, a critical bottom shear stress or critical depth for the whole lake is typically used. It is suggested here that the availability of resuspendable material must also be considered and that this availability depends on local wind characteristics. The objective of this study was to show a connection between patterns of resuspension and accumulation of sediments and the prevailing wind directions. The near-shore sediments in the shallow Lake Krankesjçn (surface area = 3 km 2 ) in southern Sweden were characterized by a 5-graded resuspension potential scale and organic content. The spatial variability in sediment characteristics was compared to local wind statistics. This comparison showed that bottoms with low resuspension potential (sandy with low organic content) were located where waves from prevailing wind direction were acting, and bottoms with high resuspension potential (soft sediments with high organic content) were located to the lee-side of the prevailing wind directions. Intensive continuous turbidity measurements showed that winds above 10 m/s in directions other than the prevailing ones brought much material in suspension, while winds in the prevailing direction did not cause any increase in turbidity. The prevailing winds erode the bottom on one side of the lake, depositing resuspended material predominantly on the opposite side, where it can be resuspended by winds from nonprevailing directions. Information about the local wind pattern can improve modeling and understanding of resuspension and redistribution of sediments in shallow lakes.
