Just on the question of whether water returning to our treatment plant has lead in it, our supply is a river supply, so upstream of us there is very little development. The water that comes into our treatment plant is generally fairly low in lead and not impacted by our discharges from the waste-water plant. Our waste-water treatment plant discharges further downstream. That's often the case for utilities—not always, but often. Our waste water could become another municipality's source water; however, I think the volumes of lead from the homes that we have would probably not add substantially to the waste-water lead burden to the next municipality. Really, the source of the lead is the lead service lines and the plumbing materials within the buildings.
