The company in this article is about 10 miles from here. We all grew up with Doe Run. Missouri is the king for lead and subsequently the king for the lead remediation superfund. I live on the Big River which through the years caught a lot of the tailings from lead smelters. It's pretty clean these days, but the gubmint still gives lots of us free 5 gallon bottled water. My well is deep AF and consistently tests fine too.
Anyway, this smelter, Doe Run, existed in that location for a very long time before the city of Herky started putting houses around it. Those people eventually filed lawsuits and that was the beginning of the end for Doe Run. It's like the old Pevely Raceway. One of the oldest dirt tracks around. Nowadays there are crap tons of big subdivisions all around it and the people continually whine about the noise on Friday and Saturday nights. They bought overpriced houses built by people who build crappy houses, close to a racetrack and then complain about the noise.
I know a bit about lead remediation too. As a contractor, under the Obama administration I had to become lead abatement certified. I know I have recounted the details here, but the bottom line is it virtually eliminated most of my replacement window jobs. The cost to remediate is high, but not as high as the cost to test ( mandatory) all 4 sides of every window in any house built before 1978. This cost had to be passed on to customers. The kicker is at the end of the day, the special bags with all the debris ( literally just regular thick plastic bags with " Danger Lead" printed on them) were to be just chucked in the dump along with any other trash. It was a money grab. They had to pay for Obamacare somehow.
The whole lead poisoning scare tactics hoopla is BS if you ask me.
