One-third of major air polluters in the U.S. have not been inspected in the last three years, according to a new study by the Environmental Working Group, which found that officials in many states are not enforcing federal clean air and water laws. Ohio, Michigan, and Texas lead the nation in failure to inspect factories with records of air and water violations. In 10 states, more than 40 percent of all Clean Water Act inspections were so-called “reconnaissance inspections,” in which inspectors were not required to get out of their cars.
