This report presents information on toxic chemical disposals and other releases into the air, land, and water, as well as information on waste management and pollution prevention activities in neighborhoods across the country. Total releases including disposals for the latest reporting year, 2010, are higher than the previous two years but lower than 2007 and prior year totals. Data show that 3.93 billion pounds of toxic chemicals were released into the environment nationwide, a 16% increase from 2009. The increase is mainly due to changes in the metal mining sector, which typically involves large facilities handling large volumes of material. In this sector, even a small change in the chemical composition of the ore being mined may lead to big changes in the amount of toxic chemicals reported nationally.
