Deloro Mine

Paper Summary:

This paper discusses the new methods that are currently being utilized that may further assist in the reduction of post-treatment effluent to a level that would not be considered hazardous to humans. The paper focuses on exploring new technologies that may help to reduce the effluent levels that are currently being introduced into the Moira River. The paper further explores new technologies that may be applicable to the reduction of arsenic at the Deloro Mine site.

From the Paper:

"As one can see, there are a number of treatment options available for the removal of arsenic in groundwater. There is no single best solution that will result in maximum results at all sites. These technologies are often combined to meet the needs of each individual situation. Treatment at the Deloro Mine uses chemical coagulation followed by sedimentation to process the effluent that will eventually be dumped back into the Moira River.The newest innovation in arsenic treatment was announced February 8, 2008 by AdEdge Technologies. This company has released a specialty adsorbent filtration system specifically designed to remove arsenic from water (Thern Inc., 2008). This technology has been awarded a grant for testing at three US sites. After testing is complete, this technology will be ready to market. This is the first filtration system specifically designed for arsenic, rather than general contaminants or metals. "
