Read this!!!!

Asarco cleanup trustee keeps trying to sell off asarco toxic land without disclosing ANY of the contaminants listed in back of the now public (10/2006) document's invoice list (see 1998 usdoj epa asarco 73 page confidential for settlement purposes only (now public) document)

A huge huge arsenic bubble is right underneath the main smelter site. Can't smell, taste that chemical. 

Slag releases its toxins gradually until after 100 years about all is released. If you do not believe, put a piece in a zip lock bag and look at bag after a week- most pieces will off-gas and puff up the bag! We use it as lawn gravel. 😟

Channel ends at asarco site, which keeps its old (but renewed) water permit to discharge water to state route (paisano).  They do their best, but some day we may be paying huge storm water fees to remove asarco's toxic waste from water we need to reuse. 

See picture of the guy overseeing lining of storm water channel with toxic black slag. Slag exposed to the wind.

He wears an ARCADIS private contractor shirt.

EPA lowers soil-lead threshold for East Helena yard cleanups Helena Independent Record

 "The U.S. Environmental Protection Agency is moving forward with more cleanup of lead in East Helena residential yards following the closing of a public comment period.

The federal agency said Friday in a news release it finalized what is called an "explanation of significant differences" document that lowers the soil-lead cleanup level at the East Helena Superfund Site from 500 parts per million to 400 ppm. The new language also removes the 1,000 ppm cleanup action level previously used to trigger yard cleanups at the site......

The EPA also recently released national guidance lowering the screening level for soil-lead in residential yards to 200 ppm, or to 100 ppm if there are multiple sources of lead contamination."
