The Adirondack Lake Survey Corp (ALS) is a not-for-profit corporation established in 1983 to gather comprehensive data on the acidification of waters in the Adirondack region of New York State. Over a four-year period, ALS conducted field investigations and collected detailed chemical, physical, and biological data from 1469 lakes and ponds, revealing the extent and magnitude of acidification. Their findings have been widely cited in research literature and have contributed to the understanding of the impact of acidic precipitation on fish populations and ecosystem damage. In addition to their lake survey, ALS also conducted intensive field studies on headwater streams in the Northeastern U.S. to assess the impacts of episodic acidification caused by storms and spring snowmelt. Through continuous monitoring of stream chemistry parameters and biological studies, ALS found that poorly buffered streams in the Adirondacks experienced significant biological impacts and a reduction in acid-sensitive fish species during acidification events. Their research has provided valuable insights into the effects of episodic acidification on stream ecosystems.Generated from the website
