EPA Long-Term Monitoring of Acidified Surface Waters
Description
This dataset compiles surface water chemistry data from 1980 to 2020 and will be updated annually with an approximate lag time of one year. Data are collected in four regions in the eastern United States (Virginia streams, New York lakes and streams, Maine and New Hampshire lakes, and Vermont lakes). These data are used to calculate trends in surface water chemistry to assess aquatic ecosystem response to changes in sulfur and nitrogen deposition. Water chemistry in this data can be influenced by the ambient flow conditions. To be included in the dataset, sites needed to have regular sampling (at least once per year for 20 years). Citation information for this dataset can be found in Data.gov's References section.
