Penobscot River Study 

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.

&quot:Sediment oxygen demand&quot: 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

reservation.
