"HIGHLANDS, Texas -- Floodwaters have inundated at least seven highly contaminated toxic waste sites near Houston, raising concerns that the pollution there might spread.

The Associated Press visited the sites this past week, some of them still only accessible by boat.

Long a center of the American petrochemical industry, the Houston metro area has more than a dozen such Superfund sites, designated by the Environmental Protection Agency as being among the most intensely contaminated places in the country.
