It’s because not all rain/runoff goes to water treatment plants. Streets and parking lots go right back to storm drains and the rivers I believe.
Parking lots alone are a big source of pollution and contamination.
It always annoys me when I see people working on their cars, changing brake pads at a Canadian Tire parking lot. Don’t do that there.
