Trace amounts of antibiotics, mood stabilizers, anti-convulsants and sex hormones have been found in drinking water across the U.S. following a five month investigation by Associated Press:
In the course of a five-month inquiry, the AP discovered that drugs have been detected in the drinking water supplies of 24 major metropolitan areas -- from Southern California to Northern New Jersey, from Detroit, Michigan, to Louisville, Kentucky.There is no federal regulation for testing these drugs in drinking water. In one example, Philadelphia, traces of 56 different drugs were found in the tap water. This included the above mentioned drugs, anti-cholesterol drugs and other pills that Americans take on a regular basis.
the concentrations of these pharmaceuticals are tiny, measured in quantities of parts per billion or trillion, far below the levels of a medical dose. Also, utilities insist their water is safe.
But the presence of so many prescription drugs -- and over-the-counter medicines like acetaminophen and ibuprofen -- in so much of our drinking water is heightening worries among scientists of long-term consequences to human health.
As water companies (this includes some bottled waters) and utilities do not routinely filter out these chemicals, which means they are returned to the water systems through the water table, following the reprocessing of waste water from human sources. We are taking these drugs and then depositing the residue into the water table and, ultimately, back into our bodies...
