Could Iron From AMD Help Reduce Global Warming?

Thursday, April 24th, 2008

by Andy McAllister, Watershed Coordinator

To those of us involved in Abandoned Mine Drainage (AMD) remediation, iron deposits and iron sludge are a fact of life. In fact, most of us are either busy trying to get the iron out of our creeks or find innovative ways to re-use the iron. However according to some, iron could be used to reduce Global Warming.

As concerns about Climate Change increase, people continue to look for new ways to lessen the amount of carbon dioxide in our atmosphere. Carbon dioxide, a gas known to promote global warming, is also called a “greenhouse gas”. This strategy of reducing carbon dioxide is known as “carbon sequestration” or carbon capture.

Because all growing vegetation absorbs carbon dioxide, promoting plant growth (eg. planting more trees) is just one method of carbon sequestration that is encouraged. A specific type of plant, the marine algae, also absorb carbon dioxide. Experiments using iron to promote phytoplankton (oceanic algae) blooms have been going on for several years and the laboratory results have shown some correlation between increased iron levels and phytoplankton growth.

Iron is just one of many substances that are important for phytoplankton growth. Iron levels in the ocean are naturally very low, and it is thought that phytoplankton growth tends to be limited because of these low iron levels. The experiments with iron and phytoplankton show that when iron levels increase, the phytoplankton populations increase dramatically (and so does their absorption of carbon dioxide). Recently, this controversial subject has resurfaced in the environmental headlines where researchers are once again, talking about dumping iron into the oceans to create algae “blooms”. The logic is this: by promoting oceanic algae blooms, we can increase absorption of atomospheric carbon dioxide and thereby reduce the levels of that particular greenhouse gas throughout the globe.

Today, we offer you links to several articles on the subject as food for thought.

Earth Day, April 22nd

Wednesday, April 16th, 2008

By Andy McAllister, Watershed Coordinator 

In September 1969, U.S. Senator Gaylord Nelson of Wisconsin, announced that in the spring of 1970 there would be a nationwide grassroots demonstration on the environment. Senator Nelson first proposed the nationwide environmental event to thrust the environment onto the national agenda and force issues of environmental protection into the legislative forefront.

The following is an excerpt of the response by Senator Nelson to Envirolink.org when asked about the history of Earth Day:
  
“Actually, the idea for Earth Day evolved over a period of seven years starting in 1962. For several years, it had been troubling me that the state of our environment was simply a non-issue in the politics of the country. Finally, in November 1962, an idea occurred to me that was, I thought, a virtual cinch to put the environment into the political “limelight” once and for all. The idea was to persuade President Kennedy to give visibility to this issue by going on a national conservation tour. I flew to Washington to discuss the proposal with Attorney General Robert Kennedy, who liked the idea. So did the President. The President began his five-day, eleven-state conservation tour in September 1963. For many reasons the tour did not succeed in putting the issue onto the national political agenda. However, it was the germ of the idea that ultimately flowered into Earth Day.

I continued to speak on environmental issues to a variety of audiences in some twenty-five states. All across the country, evidence of environmental degradation was appearing everywhere, and everyone noticed except the political establishment. The environmental issue simply was not to be found on the nation’s political agenda. The people were concerned, but the politicians were not.

After President Kennedy’s tour, I still hoped for some idea that would thrust the environment into the political mainstream. Six years would pass before the idea that became Earth Day occurred to me while on a conservation speaking tour out West in the summer of 1969. At the time, anti-Vietnam War demonstrations, called “teach-ins,” had spread to college campuses all across the nation. Suddenly, the idea occurred to me - why not organize a huge grassroots protest over what was happening to our environment?

I was satisfied that if we could tap into the environmental concerns of the general public and infuse the student anti-war energy into the environmental cause, we could generate a demonstration that would force this issue onto the political agenda. It was a big gamble, but worth a try.

At a conference in Seattle in September 1969, I announced that in the spring of 1970 there would be a nationwide grassroots demonstration on behalf of the environment and invited everyone to participate. The response was electric. Telegrams, letters, and telephone inquiries poured in from all across the country. The American people finally had a forum to express its concern about what was happening to the land, rivers, lakes, and air - and they did so with spectacular exuberance.”

That first Earth Day, April 22, 1970, coordinated by Harvard Law student Denis Hayes, was celebrated by more than 20 million individuals and is credited with spearheading the modern environmental movement. 

Interestingly enough, around the time of the celebration of the first Earth Day, the following actions were taken by the U.S. government: the establishment of the Environmental Protection Agency (EPA); the creation of the President’s Council on Environmental Quality; and the passage of amendments to the Clean Air Act.  The Clean Water Act was passed in 1972, just two years after the first Earth Day. Since then, Earth Day activities have increased throughout the nation and the environmental movement has continued to grow.

This Earth Day, WPCAMR celebrates the tremendous work of the environmental grassroots movement in Pennsylvania.  Be sure to check your local newspaper or contact your local Watershed Association or Conservation District for information about environmental events in your area.

Listed below are just a few of the many events going on throughout Western Pennsylvania as we prepare to celebrate Earth Day:

Westmoreland County:
The fourth annual Westmoreland Earth Day, noon to 5 p.m. Saturday April 19, 2008 at St. Vincent College, near Latrobe. Dozens of environmental groups from the county and elsewhere will highlight efforts to clean up and care for the natural resources of our communities.  For more information, go to the Westmoreland Earth Day Website.   

Lawrence County:
Earth Day Celebration 2008 will take place on Saturday, April 19th from 10-2:00 p.m. in Ewing Park, Ellwood City, Lawrence County. Dennis Bowman, meteorologist for KDKA, will be the featured guest. The Celebration will feature live reptiles and birds as well as live music.  Local “Environmental Heroes” will be recognized.
 

Bedford County:
The Six Mile Run Watershed Festival will be held at the Six Mile Run firehall in Defiance, PA off of State Road 1036 on Saturday, April 19, 2008 from 12:30 to 4:00pm.  It will be followed by a picnic dinner and entertainment at 4:00. 

Stream Improvement Information Sought

Friday, April 11th, 2008

by Andy McAllister, Watershed Coordinator

Do you have a stream that you think has improved due to a pollution abatement project? If you do, we need your help. The Pennsylvania Department of Environmental Protection’s Non-point Source Program has enlisted the aid of WPCAMR to help them find those improved streams.

The information you provide will assist PA DEP biologists in their efforts to target specific streams for a biological reassessment. If the stream or a segment of the stream has indeed improved, PA DEP could consider it for removal from the list of impaired waterways in the Commonwealth.

The list of impaired waters (formerly known as the 303(d) list) is now part of what is called the “Integrated List”. Impaired waters are those waterways that are not meeting their “designated use”, in other words, the biological community in those streams is adversely affected by AMD, sediment, or any number of other pollutants.

Designated uses are those uses specified in the state’s water quality standards for each water body or segment whether or not they are being attained. An example of a designated use in Pennsylvania is “CWF”, meaning a Cold Water Fishery, capable of sustaining a healthy cold water biological community (eg. a stream where trout can live and reproduce).

Removal of a stream or stream segment from the impaired waters list is a concrete way of showing that pollution reduction projects are having a positive impact on our streams.

If you think you have a stream or a segment of a stream that was impaired and is now not, we invite you to share what you know by filing out the information form at the WPCAMR “Improved PA Streams” page. By sharing your information, you can help direct state efforts to locate recovered streams.
