Measurements of Acid-Neutralizing Capacity, Conductance, and Calcium Concentrations in Adirondack Headwater Streams of New York, 1988 to 2022

This data release contains measurements of acid-neutralizing capacity, conductance at 25 degrees Celsius, and Ca concentrations for headwater stream samples collected from 1988 to 2022 in the Adirondack region of New York. Sample analyses were performed by the Adirondack Lake Survey Corporation (ALSC) laboratory and are adjusted here to be consistent with measurements made in the USGS New York Water Science Laboratory Low Ionic Strength Laboratory using relations in Lawrence (2022). Both original ALCS values and adjusted values are presented in 3 comma-separated values (CSV) files.
