Government researchers next week will
begin a study of sediment in Maine’s Penobscot River to see how
well the waterway can support aquatic life.
Starting Monday, the Environmental Protection Agency will
collect riverbed sediments from a dozen locations from Millinocket
to Bucksport for its study. The sediments will be examined after
core samples are collected.
":Sediment oxygen demand": studies like this analyze the rate
that dissolved oxygen is removed from the water due to the
decomposition of organic material in the sediments. State
environmental officials will use that information to see whether
adequate protections are in place for the river.
A mobile laboratory will be set up on the Penobscot Indian
