On May 6, 2012 three Friends of Penobscot Bay, later joined by a fourth, core sampled Stockton Harbor's intertidal flats near the GAC Chemical facility.
FOLLOW THE PHOTO SEQUENCE for a summary of the expedition and its results. One inch pvc pipe was hammered to twelve inches into the mud and the captured material pressed out of the pipe and photographed. Coring was primarily along the edge of the mudflat closest to the facility, below a shorebank waste material erosion site.
RESULTS Cores showed a significant amount of alum tainted mud at the edge of the flat closest to GAC Chemical's eroding bluff with normally colored brown mud to the south along the shore towards the Sears Island causeway. One probe struck apparent buried tarpaper or other yielding yet impervious debris.
SUGGESTED ACTIONS (1) The eroding locations need to be revegetated; otherwise this will continue to keep the mudflats alum-tainted. (2) The alum-tainted mud needs to be mapped and as much removed as possible.
