Online volunteer registration is open for the 30th annual Delaware Coastal Cleanup, to be held from 9 a.m. to noon Sept. 16.

Sponsored by the Delaware Department of Natural Resources and Environmental Control, the cleanup spans the First State’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 volunteers to scour and make cleaner.

Volunteers are encouraged to register at DNREC’s Delaware Coastal Cleanup webpage to ensure enough supplies are readied for each site. Registration will close Sept. 1.

At the 2016 Coastal Cleanup, 1,572 dedicated volunteers from civic organizations, youth groups, businesses and families collected six tons of trash from 45 sites along Delaware’s shorelines and tributaries. About one-quarter of that trash — mostly aluminum cans and plastic bottles — was recycled.

Delaware’s Cleanup is part of the Ocean Conservancy’s International Coastal Cleanup, the annual clearing of trash from coastlines, rivers, streams, and lakes by volunteers. People worldwide help each year to rid the environment of marine debris and collect detailed information on the types and quantities of refuse they find. This information is recorded on data cards and forwarded to the Center for Marine Conservation, which compiles data for all cleanups around the world. This information helps identify the source of the debris and focus efforts on eliminating or reducing it.
