Weeks after a selectman questioned the town’s use of pesticides, officials on Tuesday approved a $3,000 contract with a Burlington, Mass.-based company to evaluate two New Canaan playing fields—one that gets the chemicals and one that doesn’t. Strangely, Selectman Kathleen Corbet—who has questioned why some fields used by local kids get pesticide treatments while others don’t, and has drafted a memo making recommendations on pesticides—appeared not to know about plans to hire Tom Irwin Advisors to look at the two fields. “What are we ‘evaluating’ there?” Corbet asked during the Board of Selectmen’s regular meeting, when an agenda item to approve small contracts came up. The Board of Selectmen regularly approve contracts less than $10,000 in bulk. A note on this contract, out of the Department of Public Works, said only, “evaluate fields at Saxe and school Conner field.” While state law prohibits playing fields that are part of Saxe school grounds from receiving pesticide treatments, Conner—a town property located along Farm Road next to the middle school—does get a midsummer application.
