Today on This Week in Mercer, you’ll hear from Jeff Hewitson, the president of the Hamilton Township Board of Education, about the district’s facilities problems.

The district closed a portion of one high school two weeks ago after testing found mold, bacteria and lead-based paint in the building. After years of neglect and one-time fixes, the district’s 23 schools need more than $100 million in renovations.

At the bottom of the hour, Tahirih Smith from Sustainable Lawrence, a community group advocating for a greener community in the township.

Her group is holding a Living Local Expo at Lawrence High School from noon to 4 p.m. The event will have speakers, cooking demonstrations and showings from vendors at the high school.

So make sure to join host Michael Macagnone on 1490 WBCB at 4 p.m., or check out the show later at hamiltoninfocus.blogspot.com.
