Until , the Hamilton Water Treatment Plant backwash water was also discharged to Redhill Creek, Windermere Basin has served as a settling basin reducing the discharge of contaminated solids into Hamilton Harbour, However, because of the accumulation of deposited sediments, large areas of sediments and debris are exposed during low water.
Hamilton is a port city in the Canadian province of industrialized city in the Golden Horseshoe at the west end of Lake Ontario, Hamilton has a population of ,, and its census metropolitan area, which includes Burlington and Grimsby, has a population of ,The city is 58 kilometres (36 mi) southwest of Toronto, with which the Greater Toronto and Hamilton Area (GTHA) is. Abstract. Hamilton Harbour is located on the western end of Lake Ontario and has an area of approximately 31 square kilometers. The harbour has been designated by the International Joint Commission (IJC) as one of the 42 Areas of Concern (AOCs) within the Great Lakes.

Organic Contaminants in Hamilton Harbour Water PCB-pesticide results in Hamilton Harbour sur face water are shown in Table 4.
The BHCs and HCB were found in at least of the samples. a BHC was most frequently found (92% of the time), Cited by: Abstract Water and sediment samples collected from Hamilton Harbour in were analyzed for heavy metals and trace organic contaminants in order to obtain an improved knowledge of the concentrations of these substances and the frequency of violation of guidelines and by: The levels of organochlorine (OC) contaminants in eggs and tissues of waterbird species nesting in Hamilton Harbour, Ontario, Hamilton Harbour Trace Contaminants book International Joint Commission Area of Concern, were monitored between and PCBs, DDE, and mirex were present at the highest concentrations of the 29 organochlorines and one trace metal by: The sediment in Hamilton Harbour is contami nated by numerous chemicals including polychlori nated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), arsenic, mercury, copper, zinc, lead, etc.
(MOE ).Cited by: Water and sediment samples collected from Hamilton Harbour in were analyzed for heavy metals and trace organic contaminants in order to obtain an improved knowledge of the concentrations of.
In addition, for some stations there was evidence that PAHs were responsible for the detected deleterious effects. The study concluded that the suitability for colonization by benthic invertebrates of sediment in some areas of Hamilton Harbour is apparently limited both by contaminants and by high sediment oxygen demand.
Comprehensive GC/MS analysis of the Hamilton Harbour eggs also revealed the presence of trace amounts of o,p-dicofol, octachlorostyrene, and toxaphene. Geographic variation in contaminant levels in snapping turtle eggs from wetlands is similar to that in spottail shiners and herring gull eggs collected in the pelagic zone of the Great Lakes.

Trace metals in sediment from nearshore urban and industrialized centres of the Great Lakes are frequently at concentrations well above geological background values Total metal content in sediment, however, is a weak predictor of sediment toxicity This study examined the bioavailability of metals from Hamilton Harbour in Lake Ontario and considered variability in metal forms on a temporal.
Laurel Sefton MacDowell writes in her book An Environmental History of Canada that, “As early as the s, a fishery inspector at Hamilton Harbour discovered that fish found along the shore tasted of coal oil and that dead ducks and muskrats were coated with oil from two refineries.”.
The Randle Reef cleanup project is a major step in the process to remediate Hamilton Harbour and remove it from the list of AOCs. Randle Reef is an area of highly contaminated sediment located in the southwest corner of Hamilton Harbour. Construction of the Randle Reef Contaminated Sediment Remediation began in The presence and the extent of the plume of Hamilton Harbour water extending into Lake Ontario was determined in order to assess the importance of metal contaminant transport from Hamilton Harbour into Lake Ontario.
