Four more Tacoma schools have reported having higher than unacceptable levels of lead in their drinking water Tuesday.
Warnings went out to parents of students at Madison Head Start and Whittier, Delong and Manitou Park elementary schools.
Tacoma Public Schools decided to test their own water after lead was found in four homes near Lincoln High School.
The lead levels prompted advisories in Tacoma and Seattle for public utility customers to run their tap water before drinking it. That contamination is being caused by old gooseneck fittings connecting the homes to the water main. What’s causing the high lead levels at the two schools isn’t known.
