Following the controversy over lead levels in drinking water exceeding federal guidelines in local schools and public buildings, the Portland Water Bureau will ask the City Council on March 1 to begin a corrosion control treatment pilot to reduce customer exposure to lead in water.

The request follows a year-long water quality corrosion control study that resulted in the Portland Water Bureau recommending additional treatment to reduce lead in water levels at customer taps. The corrosion control treatment pilot is the first step in these improvements.
