The technology exists to hold polluters accountable, but can it now be used to help monitor pollution and prevent toxic messes?
In the early 2000s, residents of a small, Rust Belt city called Tonawanda, New York, began noticing something strange: Over the years, it seemed, an increasing number of people were getting sick — primarily with cancer.
Tonawanda’s a highly industrial city with more than 50 polluting facilities situated within a three-mile radius. It was common for the air to feel dense and to smell like gasoline. Residents wondered what toxic chemicals might be in the air and if they were making them sick.
