We all live on lakeshore. If you have a storm drain on your street it probably drains to a lake or river. The crap we are inadvertently putting in our rivers is cause for concern, and we must become more aware of the harm we are doing to our waterways and drinking water. A new study just done by the University of Minnesota looking at water quality finds the state of our urban rivers grim. Read about it here.
The water we have on earth is the only water we will ever have. We aren’t getting any more water, and must take care of what we have. In this above study, homeowners that use chemicals and owned dogs were the worst offenders for polluting our water run-off. This run-off goes directly down the storm drain into lakes or streams. Once we know the source of

the pollution we get at the beginning stage to solve the problem: Don’t use chemicals on your yards, always pick up after your pets and keep your sidewalks driveways and street clean! It is more complicated, but this gives you a based-line to work from!
Urban pollution is not anywhere on the magnitude of agricultural run-off polluting the Mississippi River, but urban dwellers should take it seriously.
