Recent threads about spray paint removal and a weekend activity have got me thinking.
Last Saturday I participated in a sinkhole clean-up where we were dragging lots of old trash out of a sinkhole. . . car parts, tires, old appliances, paint cans, old batteries, clothing, lots of old houshold trash (cans and bottles). Some of it had been there a long time (beer cans with the pull of tabs - you older folks remember when pop tops first came into being )
The reason for the clean-up was to clean the area to improve ground water quality and of course to improve asthetics and discourage future dumping.
During the clean-up one of the participants made a comment that perhaps by disturbing the old trash we were initially increasing the contamination of the water because we were disturbing the stuff that had sat undisturbed for many years.
I'm just curious, dose anybody have any data on this aspect of clean-ups?
