Continued bioaccumulation of toxic pollutants in aquatic species may limit their use for human consumption. Accumulation in aquatic organisms, particularly benthic species, can also cause acute and chronic toxicity to aquatic life. Finally, organic-laden solids have the effect of reducing dissolved oxygen concentration, thus creating toxic conditions. Physical Impacts. Beyond the potential for pollutant impacts on human and aquatic life, physical impacts are associated with the sedimentation, including the filling of deep pools resulting in the loss of habitat for fish and an increase in temperature.

Abandoned mine sites studies and response actions can occur in the context of drainage basins and watersheds, beginning in the uppermost and often alpine headwaters, extending through lower reaches of valley floodplains, and continuing down into mainstem river drainages where agricultural lands and municipal-industrial users occur. Water quality standards which have been developed by states are the initial targets for meeting clean water objectives; however, in some cases protecting human health and meeting environmental improvement goals can mean going beyond established standards.

G. from crushers, tailings ponds, road use). The Bunker Hill Mining and Metallurgical Complex Superfund site is an example of a mining site affected by airborne pollutants. The complex includes the Bunker Hill Mine (lead and zinc), a milling and concentration operation, a lead smelter, a silver refinery, an electrolytic zinc plant, a phosphoric acid and phosphate fertilizer plant, sulfuric acid plants, and a cadmium plant. EPA has since demolished and capped the smelter complex. The major environmental problems at the Site were caused by smelter operations and mining and milling.
