Airplane De-Icing Agents Challenge Merrimack River

By Jon Greenberg on Monday, September 22, 2008.

The air transportation industry and environmental agencies face a difficult challenge over deicing. From late fall to early spring, the only way to make planes safe to fly is to spray them with chemicals to remove frost and ice. The problem is, those chemicals can suck the oxygen out of the rivers and streams they run into.

At Manchester Boston Regional Airport, deicing agents run into the Merrimack River. According to the latest test results, the chemical load can be more than thirty times what it ought to be.

New Hampshire Public Radio’s Jon Greenberg has more.

Building on the Success of the Clean Water Act

By Jon Greenberg on Wednesday, July 23, 2008.

This week, New Hampshire Public Radio is looking at water in the Granite State.

NHPR's Jon Greenberg has been focusing on the Merrimack River.

Yesterday Jon told us how investors in the mills in Lowell and Manchester gained control over the waters of the Merrimack.

That control grew to include the legal right to dump their waste.

The 1972 Clean Water Act helped restore the river.

In our second installment, Jon looks at the legacy of that federal legislation and the people who are trying to take the river to the next level.

Winning the Right to Pollute

By Jon Greenberg on Tuesday, July 22, 2008.

This week, New Hampshire Public Radio is focusing on water and today we have the first of three reports about the Merrimack River. In simple numbers, the Merrimack is pretty impressive. It runs a hundred and eighty miles from the headwaters of the Pemigewasset River in the White Mountains to Newburyport, Massachusetts where it flows into the Atlantic. Over 5,000 square miles of land empty into the river’s watershed.

It is used by kayakers, fishers, power boaters and swimmers. It powered the launch of America’s industrial revolution and still generates electricity today. New Hampshire Public Radio’s Jon Greenberg looks at the legacy of the river and how it shaped the state in ways both obvious and obscure.
