Fog and pouring rain from a gray sky didn’t stop the Tri-Town from observing Earth Day over the weekend.

Groups in Mattapoisett, Marion and Rochester all held cleanup events Saturday, April 20 for the environmental celebration day. Earth Day is Monday, April 22.

In Mattapoisett, the Sustainability Partnership of the Mattapoisett Free Public Library held its second Earth Day event.

With grabber devices and bags for filling, participants dispersed to various sites across town — like the bike path, the town wharf and Route 6 — to pick up trash.

“I’m so glad people showed up, even with this weather,” principal organizer Barbara van Inwegen said.

By a welcome tent outside the library, Barbara van Inwegen’s granddaughter Phoebe van Inwegen stood wearing a Mother Earth costume.

The bags of waste were to be brought back to the library for weighing. Last year, participants collected 800 pounds of trash, according to Barbara van Inwegen.

The aim of the cleanup was to help the environment and reduce disposable, single-use plastics, Barbara van Inwegen said.

“Whatever we can do,” she said.

In Marion, Cub Scouts and Boy Scouts lead its annual town cleanup, an event that goes back about a decade, according to event organizer Kristen Saint Don-Campbell.

The scouts and other participants picked up trash in Washburn Park, Holmes Woods, parts of Route 6, as well as the on-ramps and overpass to Interstate 195.

“Just different people from the community just trying to do their part,” Saint Don-Campbell said.

Donations for Gifts to Give, an Acushnet-based charity, were also solicited as part of the Earth Day event.

“It’s good to see how many people really care about Marion and making sure it’s the place you want to live,” Saint Don-Campbell said.

In Rochester, the Rochester Women’s Club held an Earth Day street cleanup, an event the group has done for more than 25 years, according to president Marsha Hartley.

Participants picked up bags, gloves and cleaning supplies at the Rochester Women’s Club then cleaned trash on streets throughout town, filling up bags to be collected by the Rochester Highway Department. Many participants cleaned the very streets they lived on, according to Hartley.

Two dumpsters were also donated to the Rochester Women’s Club, Hartley said.

“This is just our effort to support Earth Day and to clean up our streets a little bit,” she said. “It’s just our effort to help the community.”
