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.
