Milwaukee banned coal-tar sealants Tuesday after a study blamed them for contaminating streams.

The Milwaukee Public Works Committee recommended a city ordinance to the general council that would ban the use of coal-tar sealants. The council approved the ban unanimously.

The ban was proposed in the wake of a recent study that found that as many as 78 percent of Milwaukee streams have toxic levels of polycyclic aromatic hydrocarbons, or PAHs.
