Due to a growing interest in the occurrence of pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs) in the aquatic environment and their potential impacts on humans and the environment, a collaborative study was conducted on these emerging contaminants in the effluents from the wastewater treatment plants (WWTPs) and in the drinking water supply system of Calgary, Alberta. A number of PhACs and EDCs were detected in the WWTP effluents, at concentrations ranging from ng/L to low mu g/L. Although these compounds were generally removed from WWTP effluents during wastewater treatment, some compounds, such as carbamazepine were more persistent. Some target PhACs and EDCs were detected at low ng/L levels in the surface and potable water in this study. Currently, there is no evidence that trace amounts of PhACs and EDCs in Calgary's waterways can have a health impact on humans, but they may pose adverse chronic effects on aquatic life.
