The presence of pharma in our water supplies is a huge problem. None of the U.S. clean water rules address this. We don't even really know the extent of the problem, because there is no testing regime. Here on the upper Potomac my town dumps all sorts of pharma and endocrine disruptors into the water that communities downstream drink from. Our town considered improving our wastewater treatment but because of the cost, won't stop until the law requires it.
