WHO recent report on pharmaceuticals in drinking water
Look at this report. http://www.who.int/water_sanitation_health/publications/2011/pharmaceuticals/en/ Key conclusions: "Trace quantities of pharmaceuticals in drinking-water are very unlikely to pose risks to human health because of the substantial margin of exposure or margin of safety between the concentrations detected and the concentrations likely to evoke a pharmacological effect. "Concerns over pharmaceuticals should not divert the attention and valuable resources of water suppliers and regulators from the various bacterial, viral and protozoan waterborne pathogens and other chemical priorities, such as lead and arsenic. "The current levels of exposure to pharmaceuticals in drinking-water also suggest that the development of formal guideline values for pharmaceuticals in the WHO Guidelines for Drinking-water Quality is unwarranted."
