The anti-phosphates ordinance Mayor Richard J. Daley signed in 1971 became the model for similar efforts that helped revive the Great Lakes. But though the city's current mayor, Daley's son, promotes Chicago as one of the nation's most environmentally friendly cities, his administration rarely enforces the ban.
Few phosphate-free dishwasher detergents are available at Jewel and Dominick's, which account for about two-thirds of the city's chain grocery stores. Most major labels and store brands still have phosphate levels ranging from 3.3 percent to 8.7 percent. The levels in some specialty detergents are as high as 20 percent.
State lawmakers are poised to step in where the city has failed to act. Legislation moving quickly through the General Assembly would outlaw all but trace amounts of phosphates in household detergents as of July 2010.
