Paper Summary:

The Deloro Mine is a now closed facility that during its operating period, contaminated ground water with high concentrations of arsenic. The arsenic now needs to be removed to prevent entry into drinking water supplied to consumers. The paper begins by outlining the most common methods of arsenic removal in use today. The author then discusses steps taken by mine owners to prevent further contamination from the disused mine and technologies put in place to remove the arsenic concentrations from the ground water. Finally, the author examines new technologies that now exist and that could facilitate more efficient and safe removal of contaminants before making his final recommendations.

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 amount of contamination at Deloro Mine is enormous. Cleanup efforts have only been marginally successful in reducing the amount of arsenic entering into individual homes. One must remember that although efforts are being taken now to clean up arsenic in the area, many private drinking wells have been contaminated for many years. The state of New Jersey faced a similar problem with widespread arsenic contamination. They resolved the issue by controlling arsenic at the point of entry into the house. They now require residential adsorption treatment system for every individual home."
