Following is an excerpt from a report in azcentral.com about mine clean up in Arizona.

Bankrupt Tucson miner Asarco LLC has agreed to pay $30 million to clean up three contaminated mine sites in Arizona and settle the state’s longstanding environmental claims against the company.

… The property, including $4 million to improve and maintain one of Arizona’s few remaining riparian areas, compensates the state for Asarco’s contamination over the years of Mineral Creek, a tributary to the Gila River in Pinal County.

… The $1.6 billion "global settlement" would clean up some 75 sites across the country that have been polluted by Asarco over more than 100 years of active mining and smelting activity.

I wonder if Orissa government can make similar claims against those mine owners in Orissa who pollute the environment. They should start looking carefully at the Sukinda Valley and the Joda-Barbil area which rank very high among polluted places in the world.
