Hi Chuck, Enviro Listservers, I do hope that you call some of the state, local, or national technical people on DDT to debunke what you have read on these web sites. The last time I called a USA/State/Local government maybe technical person, I was calling on recycling, before that was on lead in drinking water, and before that --. Where I live now in Massachusetts, it was interesting that Recyling code <2> HDPE (High Density PolyE) was only being accepted in it's clear form and not it's colored variety. The government receives a higher financial return for clear and hadn't yet figured how to do the other HDPE product. They are a bit slow around here despite everyone thinking MA is advanced.
