Major ion concentrations in surface waters is controlled by the occurrence of the Denault (dolomite) formation, and little change is caused by the mining activities. Acidification of some of the waters by acid precipitation is a potential problem, but no health hazards are likely to accrue from the effects of iron mining on the surface water quality.

Abstract Iron mining in the Schefferville, Quebec, area has resulted in the disruption of some small surface drainage systems and the discharge of large amounts of pumped groundwater into them. Major ion concentrations in surface waters is controlled by the occurrence of the Denault (dolomite) formation, and little change is caused by the mining activities.

2019-7-9 will therefore serve as baseline for assessing the impact of the exercise on ground water quality. The implications of the findings to public health are also discussed. MATERIALS AND METHODS Sample containers were thoroughly washed with detergent, rinsed with water followed by distilled water before soaking in 5% HNO 3 for about 24 hours. Water Samples were collected from hand dug wells

2018-1-10 Abstract. The aim of this study was to evaluate trends in water quality and mineral footprint along the catchment of a dam located in a coal mining area and water-stressed region. The study was conducted along the upper Olifants River, which is the catchment of Witbank Dam, in the jurisdiction of Emalahleni Local Municipality in South Africa.

2011-3-12 Mining operations use large amounts of fresh water to process recovered ore; the resulting mine effluent is typically a stew of hazardous acid-generating sulphides, toxic heavy metals, waste rock impoundments and water—and it is often deposited nearby in large free-draining piles where it can pollute land and water supplies for decades to come.
