In the United States, coal ash is a major component of the nation's industrial waste stream. In 2017, 38.2 million short tons (34.7×10 t) of fly ash, and 9.7 million short tons (8.8×10 t) of bottom ash were generated. Coal contains trace levels of arsenic, barium, beryllium, boron, cadmium, chromium, thallium, selenium, molybdenum and mercury, many of which are highly toxic to humans and other life. Coal ash, a product of combustion, concentrates these elements and can contaminate groundwater or surface wate
