He was a co-founder of the Aquidneck Island Watershed Council. The council, in co-operation with Salve Regina University conducted a three-year series of tests of the various streams and waterways comprising the island's drinking water supplies.

Recently, the Watershed Council merged with Clean Ocean Access, which has taken the lead in not only protecting drinking water on the island, but also in cleaning up storm water pollution to make the ocean and Narragansett Bay safer for recreational and commercial users.His interest in protecting the environment began in his Scouting years, where he earned, among others, merit badges in forestry, nature, canoeing, fishing, and camping.
