Most municipal sewer systems actually can't. The Milwaukee Metropolitan Sewerage District is famous for dumping billions of gallons of untreated sewage into Lake Michigan during heavy rain events. It has to pay a steep fine each time this happens, but they consider it cheaper than fixing the faults of the system. That would involve digging up half the city.

Accumulator - I did a test on PB's "biodegradable" APC back in one of my soils classes in college, and it prevented seed germination in all of the plants at concentrations as low as 5ppm. At slightly higher concentrations, it was also able to kill existing plants. Very few things AREN'T biodegradable...the difference is simply how long they take to break down, and of course how toxic they are until that point.

Now that I'm out of college and working full-time (Regional Aquatic Invasive Species Education Specialist), I spend most of my workdays fixing the human-induced problems in our local waters. The fact is, most people wait far too long to change their ways or learn anything about the impacts they have on their local lakes and streams. It's far less costly to be proactive than reactive.

Kudos to all of you that have voluntarily changed your ways to help your local environment.
