levels of fine particles in the air in Vanderburgh County were almost as high as in Manhattan, New York City. A large portion of the downtown and north side areas were declared contaminated by lead and arsenic because of factory dumping dating back to the Civil War. Contractors have been working for more than 20 years to dig up the lawns of residents to make them safe for children to play. About 18 inches of contaminated dirt is dug up from each yard then dumped in a nearby landfill. The work has many more years to go.
