Acid Rain Monitoring
In 1977, State Agricultural Experiment Station scientists initiated a program to address the problem of atmospheric deposition and its effects on crops, rangelands, forests, surface waters, and other natural and cultural resources. They called this program the National Atmospheric Deposition Program, or NADP. The NADP began as and continues to be a cooperative program with diverse participation, including federal, state, local, and tribal agencies, universities, environmental organizations, and industry.
Akwesasne contributes to this cooperative program by operating a sampling site. Starting in 1999, we have been collecting deposition samples, which are sampled from collected precipitation. Along with Akwesasne, there is a network of 250 other sites all across the United States, tracking trends in precipitation depositions.
