** FILE ** Workers conduct water tests on a pair of 96-inch storm drains that drain into the Thea Foss Waterway in this Oct. 7, 2003 file photo taken at Commencement Bay near downtown Tacoma, Wash. Twelve square miles of shoreline and tideflats on the bay west and north of downtown were listed as a single Superfund site in 1983, identifying the area as one of the worst toxic hotspots in the country. Washington Gov. Chris Gregoire, declaring Puget Sound "sick," on Wednesday, Dec. 13, 2006, proposed a massive $220 million effort over the next two years to restore and preserve the state's inland waters.
