One of Chicago's most upscale downtown neighborhoods is built on a thorium dump from the gaslight era. This is more than a little academic as Streeterville is currently being re-developed by Northwestern Hospital and the city has to be careful not to put more thorium in the air. There are something like four or five new buildings being built right now. http://articles.chicagotribune.com/2014-04-17/news/ct-thorium-radioactive-cleanup--20140417_1_chicago-river-west-chicago-radioactive-waste http://articles.chicagotribune.com/2014-04-17/news/ct-thoriu... The fix? When radiation is detected, the soil is put in bags and shipped to a facility that can dispose of it. The land in the article is going to be park. http://www.chicagoarchitecture.org/2012/08/22/work-on-chicagos-newest-lakefront-attraction-could-start-soon/ http://www.chicagoarchitecture.org/2012/08/22/work-on-chicag...
