PA Environment Digest Blog –Keep Pennsylvania Beautiful Wednesday thanked the thousands of volunteers who made the 2017 Great American Cleanup of PA a success. In 2016, 171,576 volunteers removed over 5.5 million pounds of trash. A complete report on the 2017 cleanup will be available late summer. From March 1 through May 31, individuals, families, civic groups, schools, organizations and businesses came together to renew parks, trails and recreation areas, plant flowers and trees, increase recycling and remove litter from our shared waterways and public lands. These events united communities and set an example for others to follow.
