This year's historic hurricane season exposed a little-known public health threat: Highly polluted sites that can be inundated by floodwaters, potentially spreading toxic contamination.
In Houston, more than a dozen Superfund sites were flooded by Hurricane Harvey, with breaches reported at two. In the Southeast and Puerto Rico, Superfund sites were battered by driving rains and winds from Irma and Maria.
The vulnerable sites highlighted by AP's review are scattered across the nation, but Florida, New Jersey and California have the most, and the most people living near them. They are in largely low-income, heavily minority neighborhoods, the data show.
