Here's a map of superfund sites in the US. https://hub.arcgis.com/datasets/EPA::superfund-national-prio...

Using this I see that within 10 miles of me are

- a microprocessor testing facility that contaminated soil and groundwater with 1,1,1-trichloroethane, trichloroethylene, Freon 113, 1,1-dichloroethane, and tetrachloroethane which affects 300k nearby residents

- a semiconductor manufacturer that led to "trichloroethylene, 1,1,1-trichloroethane, tetrachloroethylene, trichlorofluoroethane, and 1,1-dichloroethylene, in soils on the site and in ground water on and off the site."

- a 5-acre drum recycling plant that contaminated wells within 3 miles with trichloroethane, trichloroethylene, 1,1-dichloroethylene, and tetrachloroethylene. Affecting the drinking water of 250k residents.

- about 10-15 other sites I'm not gonna cover in detail but the contaminants include asbestos-laden dust, PCBs, dichlorobenzene, trichloroethylene, trichloroethane, chloroform, vinyl chloride, xylene, and many many more
