Merrimack River Watershed Studies
One phase of an ongoing study of the Merrimack River watershed being undertaken by the Army Corps of Engineers will be completed in 2005. Water quality sampling and analysis and computer simulations of the river's pollution levels will be finished by the end of the year.
The comprehensive study of the Merrimack began in 2005, to identify ongoing problems in the watershed. Local communities in both Massachusetts and New Hampshire, concerned about future changes in state and federal pollution regulations, began undertaking planning efforts to allow them to identify sources of pollution. Ultimately, these efforts could result in $500 million worth of sewer overflow control projects. The focus of these efforts is to identify non-point sources of pollution.
Manchester and Nashua, New Hampshire, as well as Lowell and Lawrence, Massachusetts, are contributing to the Army Corps' comprehensive watershed studies.
The goal of this work is to continue the progress in improving water quality in the Merrimack River watershed that has taken place over the last few decades.
