On May 13, 2012, friends of Penobscot Bay Ron Huber, Rob Levangie and Bob Huber
carried out a core-sampling investigation of the intertidal mudflats of Stockton Harbor.
carried out a core-sampling investigation of the intertidal mudflats of Stockton Harbor.
Route: The team started coresampling and digging near the low water mark, well
out from the shore, and worked their way landward toward an eroding slump in the
waste rich bluff upon which GAC Chemical perches above the beach and flats. They
took 15 core samples, and five digs with a clam fork.

CLAM FORK RESULTS Large cluster of mature dead clams (still with hinges) found
near low tide line. Large pieces of tarpaper were also found buried in the mud
near the low tide line; presumably blown into the flat from the roof of the now
vanished large quonset shaped building that once loomed over the flat above the flat.

CORE SAMPLING RESULTS. Mud was tainted near shore, less to no alum taint was
visible in the mud more than 20 yards out from shore, in the line of coring from the
low tide line 100yards offshore. Soft mud did not "core" well. Gray clays and sandy
mud samples cored better.

RECOMMENDATIONS. Intensify core sampling close to shore; explore outer flats for
additional tar paper wastes (tar paper a few inches below mud surface prevents clams
and other organisms from settling). Collect dead clam shells for examination.
