Remediation technologies for Arsenic Contamination at Deloro Mine, Eastern Ontario

The tiny eastern Ontario village of Deloro has been the victim of arsenic poisoning for generations. More disturbing, the environment ministry was aware of the poisoning for more than a decade before they had decided to take action. This literature will review the specific details of the contamination of the Deloro Mine site in Eastern Ontario. In addition, it will cover literature regarding specifically arsenic contamination and the effects of this poisoning.

The Poisoning of Deloro:

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.

It was revealed that tests conducted on a private property, outside of the mine, more than a decade earlier, showed arsenic contamination in the soil an average of 30 times higher than then acceptable levels, with the maximum approximately 240 times the acceptable level. Although residents had known for years that there was a problem at the mine site itself, they were unaware that it had actually extended to their village as well.

It was believed that the arsenic in the village came from the smoke stacks of the refinery that closed in 1961. In addition, McAndrew's 1999 articl

e surmises that recent contamination occurred due to dust blown by the wind from the piles of mine wastes (tailings) sitting on the site.

The tailings piles were eventually covered by rock in order to prevent the dust from being blown further into town, which is just west of the mine property boundary.

Yanagisawa's ministry's finding put forth that Deloro residents were in "no more significant health risks than other Ontario citizens."

However, clearly there was issues as ministry workers and even a construction crew that extended a natural-gas pipeline had to wear containment suits, while the crew that installed the original pipeline two-to-three years ago wore normal work clothing.

However, residents are not comfortable with the ministry reassurances, especially given the ministry's past withholding of evidence, notes Yanagisawa. In fact, the ministry's commitment to spend $1.66 million for short-term maintenance of drinking water, reduction of radon gas, removal of pockets of contaminated soil, and the fencing of the mine site, did little to ease their fears. Although the government workers completed the $800,000 chain link fence, it was too little, too late.

Yanagisawa further cites sources that uncovered the fact that the mine site was supposed to be fenced and remediated in the 1950s. This concurs with McAndrew's 1999 findings that the ministry ignored the arsenic laden tailings to drift into town.

In addition, Yanagisawa goes beyond McAndrews' 1999 report and discusses the effects on Moira Lake. In the summer of 1999, the residents of Moira Lake were warned by the Ministry of Environment officials not to drink the water or eat the fish from the lake.

She notes, "Arsenic has been found in sediment about 45 kilometres downstream, where the Moira empties into the Bay of Quinte after passing through Tweed and Belleville."

McAndrew's 2000 article notes that residents were further given information to protect themselves against contamination, seemingly in contrast to their assurances that all was well in the village of Deloro, as they noted in Yanagisawa.

One resident was specifically told to wear gloves when she wanted to garden in the contaminated soil around her home, as a precaution.

Again, furthering the doubt residents had in government assurances.

The 350-hectare site of the closed mine and refinery has long since been considered to be the most contaminated piece of land in Ontario. Ministry officials have admitted to this much, and have estimated that it could take up to $30 million to remediate the… READ MORE

Literature Review (20%)

A literature review is an overview of significant texts relating to your specific field of study. It exists in order to prove your authoritative understanding of all significant research in the field, which can in turn help you to demonstrate the appropriateness and role of your own research. A successful literature review must be defined by a guiding concept such as your research objective, or the problem or issue you wish to discuss.

Your literature review should be in essay form, approximately 4 double-spaced pages (These pages will likely be able to be incorporated directly into your final project.) It should refer to roughly 5-7 sources you should locate these sources through independent research. The Literature Review is a structured explanation of what these sources say, why they are significant for research in your selected field, and how their claims relate to each other. The sources that you select might include: Government studies, industry studies, university-conducted research, student thesis, authoritative institutional websites, articles in professional journals, books, conference papers. Since the Literature Review is devoted to your analysis of other published research related to your field, every item that you include in your Literature Review must have its own list of *****References***** or *****Works Cited*****.

Structure:

The introduction of your Literature Review should provide a brief overview of your intended research project, or the question that you wish to answer through your research. You*****re welcome to use the first-person pronouns (*****I*****/*****we*****) in the introduction, although you probably should avoid them in the body of the paper. In the introduction, you should summarize the general patterns that you find in the sources you will be analyzing, whether they be patterns of information, debates, themes, and/or methodologies.

The highest ambition of a Literature Review is the ability to establish relationships between your different sources. Therefore, you should try to structure your paper in ways that foregrounds their relationships (i.e., similarities or differences). For that reason, I encourage you to avoid simply devoting one paragraph to each source, or beginning each paragraph with an author*****s name; try instead to organize your body paragraphs around issues or topics, indicating the way in which different sources apply to them. You may also wish to group or organize your sources according to debates (and sides thereof) or methodologies or results. Generally, strong Literature Reviews bring different sources into *****dialogue***** in each paragraph. You may refer to the same source at several different points throughout the paper, although you should avoid simple repetition by focusing on different elements of that source each time you mention it.

Your literature review should include a *****Works Cited***** page at the end, in a citation style appropriate to your field of study.

Evaluation Criteria

I will evaluate the review according to these expectations:

Rhetorical Awareness

Shows awareness of who will use the report and for what purpose

Indicates the role of this literature review for your larger research project

Content

Focuses on issues in and relationships between texts; doesn*****t merely summarize texts

Analyzes and explains the significance of the texts, justifying their authority and their inclusion

"Develops" and *****interprets***** information, focusing on conclusions and implications, rather than simply facts.

Includes current sources--may include historical sources, but acknowledges the most recent thinking and research about the issue

Includes authoritative sources*****”accounts for authority of included selections.

Answers who-what-where-why-when-with what results-so what?

Organization

Organized according to topics or issues rather than by sources

Clearly attributes and cites ideas, avoiding confusion between your points and those of the texts you*****re analyzing

Style

Uses lots of concrete words, good action verbs

Avoids overusing the verb *****says***** or *****claims*****, and strives for more specific signal verbs

The *****'s own voice dominates (not a string of quotes)

Follows the rules of Standard Writing English
