Recent water analysis’s conducted in cities around the world have demonstrated that pharmaceutical drugs are present in municipal water supplies.

According to CTV News, “Canadians' tap water may contain traces of prescription drugs”.

Birth control pills, cancer drugs and a host of other pharmaceuticals are making their way into the water supply because the human body doesn't always absorb all the medication it ingests, and some are flushed down the drain, says Gord Miller, Ontario's environmental commissioner.

These drugs are also being prescribed at alarming levels, and once these drugs are consumed they enter the sewage treatment centers that dump into the rivers and streams that later on are used to make drinking water downstream.

Most pharmaceutical chemicals are not regulated by the Environmental Protection Agency, therefore, there is no enforced limit of pharmaceuticals in the drinking water.

A vast array of pharmaceuticals - including antibiotics, anti-convulsants, mood stabilizers and sex hormones - have been found in the drinking water supplies of at least 41 million Americans, an Associated Press investigation shows.

Water providers rarely disclose results of pharmaceutical screenings, unless pressed, the AP found. For example, the head of a group representing major California suppliers said the public "doesn't know how to interpret the information" and might be unduly alarmed.

Scientists say more prescription drugs are likely to find their way into our drinking water, because prescription drugs are getting stronger and baby boomers are taking more of them as they grow older.

Since prescription drugs simply pass through municipal water and waste-water treatment plants, the concentration of prescription drugs in tap water is increasing every minute and eventually will be at alarming levels.
