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.

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."
