One has to wonder why the EPA is picking on WWs as a hazard. Think about it. While there is no argument that ww's are distributed along our highways what about the greater contamination risks such as oils, fuels, chemicals that are left by vehicle I'm sure in far excess of WW's? Those items all drip onto the highways and are flushed off by rains, getting into our water systems at levels 100s or
1000s more than a few lead WW's. heck in my area the risk from farm chemicals is probably a million times that of lead. It's just a lot more junk science.
