A group of former and current residents of Treasure Island, a one-time San Francisco Bay naval base, on Jan. 23 sued consultants Tetra Tech and Shaw Environmental, the U.S. Navy, developer Lennar Inc. and others, seeking $2 billion in damages and an injunction to stop work of some 8,000 residential units there until all alleged toxic and radioactive material at the site is removed.
The class-action suit claims repercussions from exposure to radiation and toxic substances.
