The students, all from the Jaffrey-Rindge School, will be divided into small groups, and guided along the trail to the peak of the monadnock. At the top, they will have the opportunity to visit the air monitoring station, a fire tower, and vehicle displays. They will also participate in discussions about visibility, air quality, and how health and outdoor air are related. BNH and DES staff will be available to discuss some of the geology of the surroundings, as well. May 22 has been scheduled as a rain date. The air monitoring station is one of the state’s 20 different site locations which measure and track numerous air pollutants around the state. DES and other organizations use the data that is collected to determine the status of New Hampshire’s air quality, predict air pollution episodes, enact protective measures and warnings, protect public health, and protect the natural environment.
