I've taken a non-educated look and you're correct that asbestos is a thing there ([1]). I also found this page that lists additional hazards around Atlas silos ([2]). In short: - Soil contamination from petroleum chemicals and/or from polychlorinated biphenyls - Groundwater contamination from trichloroethylene - "no evidence of radioactive contamination" Both chemicals (polychlorinated biphenyls and trichloroethylene) are common pollutants in the SF Bay Area, so for many Hacker News readers the silo will feel like home. 1. https://www.mesothelioma.com/states/north-dakota/ https://www.mesothelioma.com/states/north-dakota/ 2. https://cdphe.colorado.gov/atlas-missile-sites https://cdphe.colorado.gov/atlas-missile-sites
