Popis: In a vast majority of cases solid municipal wastes are disposed through sanitary landfill operations. However, as water percolates through such wastes, it dissolves inorganic and organic components thereby producing contaminated leachates which may constitute a large pollution potential. Such studies show that the organic contaminants emanate at high concentrations during active stages of decomposition and decrease with time as fill stabilizes but the inorganic contaminants on the other hand continue to leach for decades from a site. It is therefore pertinent that the release of chemical contaminants from each municipal landfill operation be established and documented. Such an information in turn can be valuable in the design and long term use of a landfill site. The metropolitan area of the City of Moncton comprises a population base of over 100,000 people and is situated on the bank of the Petitcodiac River. The landfill sites located on the river bank are apt to deliver their chemical contaminants into the river. This may influence the aquatic life and also constitute a potential health hazard for the public at large. The present report describes the physico-chemical data of the leachates of these landfill sites, their inorganic contents and in particular the heavymore » metals. In addition to leachate analysis, water and sediment samples from the river have also been analyzed for comparison.« less
