The U.S. Army Corps of Engineers this week began field work to ensure Vineyard beaches used for practice bombing training during World War II are cleared of practice munitions.

The work, which will continue into 2012, also involves the Massachusetts Department of Conservation and Recreation and The Trustees of Reservations.

The field work, which should be completed by June next year, began on Monday at Cape Pogue. It will progress to South Beach and Tisbury Great Pond, according to the Corps’ New England district project manager, Carol Ann Charette.

Geophysical surveys on the land and beach areas to determine if there are any buried ordnance items will be performed first. Bathymetric surveying then will determine the bottom depth in both Cape Pogue Bay and Tisbury Great Pond. The Corps will seed inert items off the shore of Tisbury Great Pond and South Beach to track how these items move in the ocean currents offshore.

Further surveys in the deep water offshore, the shallow waters near the shoreline, the beaches, dunes, upland land, land adjacent to ponds, and respective pond areas will follow.

As the work progresses, residents will be notified with door hangers when the contractor will be performing work on their property. The Corps requires access to private property and is in the process of finalizing their attempts at acquiring rights of entry. Residents who have been contacted by the Corps and have not returned rights of entry can contact Ms. Charette at 978-318-8605 or by e-mail at carol.a.charette@usace.army.mil. Any parcel for which a right of entry has not been received may not be included in these projects at this time or in the future.
