Most minerals from groundwater, including iron, will be absorbed by water. Large amounts of iron in drinking water can give it an unpleasant metallic taste. Iron is an essential element in human nutrition, and the health effects of iron in drinking water may include warding off fatigue and anemia.
Water quality is degraded as a result of surface runoff and leachate that are frequently generated from large volume overburden and tailings that are produced during iron ore mining and subsequent...
An uncontrolled release of Iron Mountain acid mine drainage could potentially threaten the quality of the drinkingwater supply. Detailed studies beginning in the 1970s have demonstrated that Iron Mountain produces some of the most acidic waters in the world (Nordstrom 1977, Nordstrom amp; Alpers 1999a, Nordstrom and others, 2000).
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have effect on the quality of
Aeration of ironcontaining layers in the soil can affect the quality of both groundwater and surface water if the groundwater table is lowered or nitrate leaching takes place. Dissolution of iron can occur as a result of oxidation and decrease in pH. ANALYTICAL METHODS Iron in water can be determined by atomic absorption spectrometry (detection limit 1 #181;g/litre) or by colorimetric methods (detection limit 5
The presence of iron in ground water is a direct result of its natural existence in underground rock formations and precipitation water that infiltrates through these formations. As the water moves through the rocks some of the iron dissolves and accumulates in aquifers which serve as a source for ground water.
Commonly, however, the water dissolves any metal compounds present resulting in high concentrations of metals, particularly iron, zinc, copper, lead, cadmium, manganese and aluminium. The quality....
The Effects of Iron in Water on Aquatic Life Iron Levels in Water. When unusually high amounts of iron exist in water, this is usually due to pollution related to... Benefits. Iron is vital to the life of all aquatic creatures, especially mollusks and green plants. Iron promotes enzyme... Toxicity.
Furthermore, the presence of excess iron in water affects the taste as well as promotes the growth of iron bacteria that increases the rate of rusting (Chukwu et al. 2008). From the foregoing, the result of the water quality in EdegeMbeki mining district was within the permissible limit values concerning the physicochemical parameters.
