Boston Public Schools superintendent Tommy Chang spoke on Wednesday after elevated lead levels were discovered inside seven more schools.
With just days before the start of the school year, Superintendent Chang is trying to reassure parents about the elevated lead levels found in the water in seven schools.
Chang said, "we're going to test and test until we make sure the water is safe."
Lead levels were discovered above 15 parts per billion at water fountains.
These fountains have now been deactivated and replaced with bottle water coolers.
Chang added, "every single day in the morning we are going to flush every single water fountain. We know that is critical to getting the lead that's been in the pipeline overnight, out."
City and school leaders were in Boston on Wednesday along with new and returning teachers to kick off the year.
One parent, Bobbi Denapoli spoke to necn and said, "they have to figure out what's the source, if the lead is in the pipes then where else is it?"
Mayor Marty Walsh said the schools were built in the early 1900s and "all have lead pipes."
He added, "we will continue to test throughout the summer."
