Sully Historic Site - Fairfax County Watershed Cleanup 2025

Celebrate the 10th Fairfax County Spring Watershed Cleanup! The Nature Conservancy is once again partnering with the Fairfax County Park Authority in Northern Virginia for a watershed cleanup. This spring cleaning event will remove tires, plastic bottles, cans and other debris from local waterways, preventing trash from reaching the nation’s largest estuary, the Chesapeake Bay.

Sunday, March 23, 2025 from 10:00 a.m. - 12:00 p.m.

10 volunteers needed

If you're planning to bring a group of 6 or more people, email Jen Dalke, volunteer program manager, at [email protected] so we can plan accordingly.

You will receive an email with event details about a week before the workday.

Your participation in this workday keeps trash from polluting our drinking water and from harming animals. Our marine scientists see trash, primarily plastic, floating in the ocean every time they go offshore. Last year, our university partners at NCSU analyzed the stomach contents of 50 fish (mahi, wahoo, and blue marlin) caught in a major fishing tournament. They were looking for microplastics and found them in every single stomach sampled. Our partners at VCU have been deploying tags on the endangered Atlantic sturgeon in the James River. This past fall, they tagged an Atlantic sturgeon after freeing it from plastic debris. We're also seeing plastic on the seafloor in the deep sea.

You are making a dfference! Through nine years of this cleanup, you've collectively:

• donated 9,763 hours
• removed 29.1 tons of trash
• cleaned 150+ miles of local streams, shorelines and trails

Through your support of The Nature Conservancy and Fairfax County Park Authority, we can continue to preserve and protect the places you care for most.
