Mining and Water Quality USGS

Mine drainage is metalrich water formed from a chemical reaction between water and rocks containing sulfurbearing minerals The resulting chemicals in the water are sulfuric acid and dissolved iron Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainageWater 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(PDF) IMPACTS OF IRON ORE MINING ON WATER QUALITY AND Oct 01, 1981 Applied Geography (1981), /,287296 287 1981 Butterwonhs Effects of iron mining on surface water quality in the Schefferville area John J Drake Department of Geography, McMaster University, Hamilton, Ontario 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 Effects of iron mining on surface water quality in the Mining can affect water quality in three principal ways: example, while 4mgL1) of iron would not present a toxic effect at a pH of 55, as little as 09mgL1 of iron (PDF) Mining Impacts on the Fresh Water Environment Iron in water has many effects on aquatic life, both good and bad Iron (Fe) occurs naturally in water at a rate of roughly 13 parts per billion (ppb) in ocean water, about 1 part per million (ppm) in river water and 100ppm in groundwater Iron comes from various minerals in the soil, which is why The Effects of Iron in Water on Aquatic Life Cuteness
