German scientists report that anywhere from 30 to 60 drugs can be measured in a typical water sample. Pharmaceutical drugs given to people and domestic animals (of which 50-90% is excreted unchanged) can range from antibiotics to hormones, pain-killers, tranqualizers or chemotherapy agents. All are being measured in surface water, in ground water and drinking water at the tap. Hospital septic tanks, health care industries and feed-lots are the major sources of these problems. Another dilemma resulting from drugs in the environment is bacteria developing resistance to antibiotics.

In Europe, the Danube, the Po River and the entire North Sea contains clofibric acid (CA), a drug used to lower cholesterol levels, just to give you an idea on how far something can spread.

We are all informed that we can tolerate a certain amount, but what about constantly drinking or bathing in it, as the fish do! No one knows the bio-accumulative long term effect. I think 3 legged frogs are telling us something.
