WACO School District will address a mold problem at one of their buildings over Thanksgiving break. The plan was announced yesterday, after the district received the results from an inspection prompted by concerns from teachers at the elementary school in Crawfordsville.. Superintendent Darrell Smith says it isn’t widespread, but they found levels higher than normal in the carpeting and duct-work. He estimates the cost of removing the mold at around $50,000. That will be paid for with the district’s 1 cent sales tax.
