Abstract
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.

State of the Art in Arsenic Removal Technology

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."

Abstract
The paper uses a qualitative review of existing literature concerning arsenic characteristics, regional and site specific geology and hydrogeology, and remediation methods, to explore the arsenic contamination of groundwater in Deloro Village, Madoc, Eastern Ontario, Canada. The paper also provides recommendations on more effective and efficient means of remediation for the site and similar contaminated areas.

From the Paper
"The Deloro Mine, in eastern Ontario, is a significant player whose activities has resulted in both surface and subsurface arsenic contamination of both soil and water, at the mine site, and off-site as well. Gold mining and smelting, with arsenic removal, was established in 1886, at Deloro. The health and safety of Deloro workers was compromised due to high levels of metal in their bodies, specifically lead and arsenic. Environmental problems were also an issue, including the air deposition of arsenic dust. This air deposition contamination was so detrimental that residents were unable to hang out their laundry during smelter operation, for years, because of the stack soot high in metals. In the 1960s, the Ministry of the Environment (MOE) Water Resources Commission found water samples to be high in arsenic. "

Abstract
This paper evaluates remediation technologies for arsenic contamination at the Deloro mine in Eastern Ontario, Canada. It first discusses a background of the site and contamination in the area. The paper then looks at the geology and hydrogeology of the site and the scope of the remediation project. Next, the paper focuses on the properties and health effects of arsenic contamination.

Motility In Groundwater

From the Paper
"Arsenic is highly mobile in groundwater, largely due to oxidation processes. Aside from ease in traveling in slow moving streams. It is highly reactive and when settled in sediments can be re-released into the water column by chemical or physical activity. Arsenic released into surface water through the break down of arsenopyrite can result in higher concentrations in ground water. Groundwater with higher flow rates is especially prone to highly mobile forms of arsenics. Organic forms of arsenic can release highly mobile elemental arsenic into the water by means of oxidation and reduction reactions."

Abstract
The paper analyzes the issue of arsenic in drinking water and discusses different points of view regarding this problem. The paper also raises concerns regarding any contradicting research. The paper discusses limitations and developments and concludes that arsenic in the drinking water is an important concern that must be addressed in the near future, as is puts global health at risk.

From the Paper
"In the past few years, the topic of health as it relates to environmental awareness has emerged as a significant concern for global leaders, government officials and the common family. Arsenic, a ubiquitous element found in the atmosphere, soils, rocks, natural waters and organisms, is one of the current leading environmental health issues. Most environmental arsenic problems are the result of mobilization under natural conditions, but man has contributed to the release of arsenic in the environment through mining activity, combustion of fossil fuels, herbicides, and the use of arsenic as an additive to livestock feed."

Abstract
This paper examines the extent to which manure is a threat to groundwater supplies (which are a source of much of the nation's drinking water), looking at what farm practices lead to the current levels of pollution and how those methods might be changed so that the groundwater supply can be kept safe in the future.

Abstract
This paper focuses on the California Office of Environmental Health Hazard Assessment's publication regrading the chemical arsenic. The chemical with respect to carcinogenicities, exposures, research, and other considerations are discussed. In addition to the website with the report, over 30 other sources were used to make this report.

From the Paper
"Arsenic in the drinking water supply has been the subject of much controversy and debate in state and national government. The allowable amount had remained unchanged for decades at 50 parts per billion until fairly recent years. While an earlier presidential administration attempted to curtail the amount allowable in the water supply, later politicians did the contrary. There is little doubt that science supports the toxicity and carcinogenicity, but attempts to undermine the significance of findings has stalled stricter regulation on the national level."

Abstract
The paper discusses the arsenic poisoning in the tiny eastern Ontario village of Deloro and how the environment ministry was aware of this for more than a decade before it decided to take action. The paper reviews the literature on the poisoning of Deloro and on arsenic contamination in general.

From the Paper
"The provincial government had known for more than a decade that the people of Deloro had been breathing arsenic-laden air and living with arsenic-poisoned soil, according to McAndrew in his 1999 article. However, on June 10th, 1999 the approximately 175 residents learned the truth, during a community meeting organized by the ministry to inform the residents about the cleanup efforts that would be conducted at the abandoned Deloro gold mine and smelter."

Abstract
This paper discusses the various issues surrounding the shrinking supply of groundwater (such as groundwater mining) and how we can deal with those issues to protect this vital resource.

Abstract
The paper examines "Arsenic and Old Lace" as not just a comedy but a farce, even though the central topic is murder. The paper discusses how even though most of the characters are involved in murdering people or burying them, there is only one true villain. All the characters are likable and are accepted with their own explanations of what they do, except for Jonathan. The paper illustrates how this distinction is achieved through character portrayal, physical appearance, references to other horror films and techniques such as music.
