The Environmental Protection Agency today released its Toxic Release Inventory, the most authoritative accounting of toxic chemicals put into the air, water and land of the United States.

What follows is a list of the facilities that polluted the most, by weight. Be cautioned, however. That doesn't mean that these are necessarily the facilities that pose the greatest health or environmental risks. Some contaminants are dangerous at exceedingly low levels, and the method and location of disposal can have a lot to do with the impact of the pollution.

The Toxic Release Inventory is the best tool for local watchdogs to track pollution from local facilities, which are most likely to have an impact locally. Use this list to whet your appetite, then go to the TRI Explorer, and search for facilities that are present in your county (and don't forget those upwind).

That process is exactly what Congress intended when it mandated the creation of the Toxic Release Inventory. Armed with knowledge, citizens have pressured companies (and government-run facilities) to reduce their pollution dramatically. The inventory isn't a perfect accounting (many of the numbers are estimates based on the chemicals used, hours of operation and pollution control technologies employed; the most recent data available is for 2006).

But it's the best information available. Use it.
