How long have pharmaceuticals been in water?
The presence of pharmaceuticals and other personal care products in water is not new. They likely have been present in water supply sources for as long as such products have been in use. What is new is that advances in laboratory technology have made it possible to detect and measure them at extremely low levels. These lab methods are not widely available and are still experimental and under development.
