A much-needed recovery period from knee surgery, coupled with the holiday season, left little time for working anywhere but on the computer these past two weeks. No interviews, few e-mails, mostly surfing government Web pages. And the effort produced an alarming deja vu.

While researching a story for NUVO readers in Indianapolis on the connection between autism and toxic chemicals, I returned to territory familiar from my stint as an environmental writer at the Indiana Department of Environmental Management (IDEM) from 1996-2000. I spent hours analyzing Indiana's Toxic Release Inventory (TRI), a gauge for how polluted Indiana or any other state is.

This Community-Right-to-Know tool is a U.S. Environmental Protection Agency (EPA) database through which polluters quantify their annual releases of "nearly" 650 chemicals into the nation's air, water and land, according to the TRI Program Fact Sheet.
