In the early 1980s cleanup efforts began on the Brandywine. These first ventures involved volunteers, then mostly BVA members, cleaning up roadside trash along the creek and pulling large items out of the stream. With help from local townships, many of the roadside dumping sites were made inaccessible and the problem solved. The cleanup then evolved into a canoe based event which began on the west branch. Partnering with the Northbrook Canoe Company, BVA attracted volunteers from schools, local businesses, and Scouts to join the effort. Early cleanups would fill two dumpsters and collect as many as 400 tires. Over time the cleanup has expanded to 25 miles of stream and includes the east branch below Downingtown and the west branch in Coatesville and downstream to Lenape. Judging from the reduced amount of trash and number of tires in recent years, the cleanups are having the intended effect. The event is the last Saturday of April and attracts over 200 volunteers.
