The city allegedly used the wet removal technique, which uses high-pressure water hoses to blast the toxic substance from ceilings, walls, pipes and other structures. This method can scatter the potentially hazard asbestos substances, endangering the health of nearby residents. If asbestos fibers are inhaled or ingested it can lead to mesothelioma, a serious, painful, and usually terminal form of cancer that may take years to develop. The Environmental Protection Agency's toxicologists and asbestos experts believe the wet removal techniques have not been adequately tested for safety. EPA's current regulations do not approve this removal method.
