PA Environment Digest Blog –Pick Up Pennsylvania, a program of Keep Pennsylvania Beautiful, runs from September 1 through November 30. During this time, residents are encouraged to improve their communities by picking up litter. The program supports the Ocean Conservancy’s International Coastal Cleanup, the largest volunteer-based cleanup focusing on the health of the world’s waterways and oceans. Cleanups can be along waterways or be land-based since a significant portion of waterway pollution originates on land. When it rains, trash on sidewalks and streets accumulates and can be swept into storm drains. Most storm drain systems discharge directly into the nearest creek or river, eventually flowing to the ocean taking all the trash with it.
