Park haze issue
subject of talk
at the library
The March program for the Rappahannock Library’s First Friday Series will be presented jointly with the Rappahannock League for Environmental Protection (RLEP) at 8 p.m. on March 6.
The program will include a video titled “Sulfates and Haze” that will be shown on the library’s new video projector. Rolf Gubler, air quality monitoring specialist for Shenandoah National Park, will answer questions following the video.
An air quality monitoring program has been in effect for more than 10 years in seven national parks across the nation, including Shenandoah. Now data has been evaluated to determine the air quality problem, its sources and recommendations to deal with the problem. Other data has been compiled from as early as 1950 indicating that distant views from certain park overlooks has been reduced by over 40 percent.
Studies from the other parks show Shenandoah’s air quality to be more polluted than the other parks. In addition to increased haze, the rainfall has become more acidic (ph 4.2, 10 times greater than unpolluted rain). This has an effect on the environment in many ways; mpst pronounced is the elimination or weakening of certain plant species and the native brook trout in the streams. , Rappahannock citizens are associated with the air quality problems of the park through observing the mountains, growing plants dependent on the rain and simply breathing. Community members can learn more about what is being done to correct air quality problems and prevent farther deterioration.
The video presentation and Mr. Gubler’s discussion should give the participants a better idea of what individuals can do to help.
The program will be held at the new Rappahannock County Library. Next month’s program, entitled "The Natural World of .Greenway," will feature John Trott, an Audubon bird photographer. It will be held April 3.
