Unfortunately, we all know a lot of towns that do not have sewage treatment plants. There could be a river that meanders through farmland and forests. I know the EPA would be looking at the different water bodies. Can it distinguish between what comes out of a septic tank and the different types of nitrogen? Can it distinguish between those to a degree that is foolproof?
