BETHEL — The Mahoosuc Land Trust will hold its September event of the 2015 speaker series at 7 p.m. Wednesday, Sept. 23, in McLaughlin Auditorium at Gould Academy.

The talk will be “This is your Drinking Water.”

The presentation is a response to a survey of members and friends of the Land Trust earlier this year, when water quality emerged as a common interest.

Laurel Jackson, a water resources specialist at the Portland Water District, will be among the speakers. She has led events around the Sebago Lake watershed, which encompasses 450 square miles extending from Standish to Bethel. The Portland Water District is engaged in watershed protection and was a partner in a recent conservation easement in Albany which helped ensure clean water for Maine residents.
