washing our clothes are a source. every time we wash our clothes –whether it's the fibers, the chemicals associated with them, and of course dirt and other things that come out into the wash water – they exit out of our house and into the waste water treatment plant, where some of them will still make their way out to the lake.
a lot of people clean out their lint trap in their dryer. they are in the habit of it and they do it because they're told it's a safety hazard. we're not talking about anything different in washing machines – we're talking about wet lint instead of dry lint.
