Homeopathic Drugs found in US Drinking Water

Via Skeptico comes this story;

Despite multiple testing scenarios, and despite using the most advanced and sensitive equipment available, we were not able to find even one molecule of the homeopathic remedies in any of the tap water samples we examined. While this would not be a problem with allopathic medicines, homeopathic remedies are stronger the more dilute they are. This means that samples of water we tested containing zero molecules of, for example Arsenicum Album, would be potentized at the maximum strength possible, and as such could present real risks to the American public who would be unknowingly consuming these powerful homeopathic drugs.
