Arsenic Leaching

Heavy metals, including arsenic from abandoned mines, are easily transported with sediment and deposited in waterbodies such as reservoirs and lakes, creating critical water quality issues when they are released. Understanding the leaching of heavy metals is necessary for developing efficient water quality improvement plans. This study investigated how arsenic leaches from different soil and sediment types and responds to hydrologic conditions to identify areas susceptible to arsenic contamination. In this study, batch- and column-leaching tests and sequential extraction procedures were used to examine arsenic leaching processes in detail. The results showed that most arsenic-loaded sediments accumulated in the vicinity of a reservoir inlet, and arsenic in reservoir beds have a higher leaching potential than those from agricultural land and stream beds. Arsenic deposited at the bottom of reservoirs had higher mobility than that in the other soils and sediments, and arsenic leaching was closely associated with the acidity of water. In addition, arsenic leaching was found to be responsive to seasons (wet or dry) as its mobilization is controlled by organic compounds that vary over time. The results suggested that temporal variations in the hydrochemical composition of reservoir water should be considered when defining a management plan for reservoir water quality.

Water quality pollution from abandoned mines is becoming an issue of growing awareness and concern. This concern is exacerbated by the fact that there are countless numbers of inoperative facilities with serious environmental, safety, and health problems. Abandoned tailings piles eroding heavy metals and sediment into watercourses, flooded tunnels and open pits filled with toxic water, unmarked open shafts and adits, and rotting timbers are some of the hazards facing unsuspecting humans and wildlife. The purpose of this paper is to identify and characterize water quality sources at abandoned hardrock mine sites and best management practices (BMPs) used to control polluted runoff. There is a need to clearly define the best approach for controlling nonpoint pollution sources at abandoned mines. These are issues that could be addressed in reauthorization of the Clean Water Act.

In this study, batch- and column-leaching tests and sequential extraction procedures were used to examine arsenic leaching processes in detail. The results showed that most arsenic-loaded sediments accumulated in the vicinity of a reservoir inlet, and arsenic in reservoir beds have a higher leaching potential than those from agricultural land and river beds. Arsenic deposited at the bottom of reservoirs had higher mobility than that in the other soils, and arsenic leaching was closely associated with the acidity of water. In addition, arsenic leaching was found to be responsive to seasons (wet or dry) as its mobilization is controlled by organic compounds that vary over time.
