Online volunteer registration is open for the 31st annual Delaware Coastal Cleanup, to be held from 9 a.m. to noon Sept. 15.

Sponsored by the Delaware Department of Natural Resources and Environmental Control, the cleanup spans Delaware’s 97-mile eastern coastline and includes river and ocean shorelines and wetland and watershed areas. This year, more than 45 sites in New Castle, Kent and Sussex counties are targeted for cleanup by volunteers.

Individual volunteers and groups are strongly encouraged to register at to ensure enough supplies are readied for each site. Pre-registration will close Sept. 5.

Groups of 10 volunteers or more also are asked to contact Delaware Coastal Cleanup Coordinator Joanna Wilson at 739-9902 or, or the appropriate zone captain listed on the website for advance site placement.

Delaware’s Cleanup is part of the Ocean Conservancy’s International Coastal Cleanup, the world’s largest annual clearing of trash from coastlines, rivers, streams and lakes by volunteers.
