The big headline for today is that drugs have been found in city tap water. This is not new news; we've know for some time that trace amounts of pharmaceutical drugs have been ending up in our watersheds. Why? Because when people take pills, the drugs comes out in the urine and then end up in recycling back into our tap water.
What can be done to stop this? Well, for one, you might consider not running out and getting an antibiotic at every sniffle. Two, you might consider trying holistic remedies instead of antidepressants for depression (which are really no better than a placebo anyway according to a recent study).
