Chemical properties of groundwater (DP1.20092.001)

This data product contains the quality-controlled, native sampling resolution data from NEON's groundwater chemistry sampling protocol. Subsamples are analyzed at NEON domain headquarters for alkalinity and acid neutralizing capacity (ANC); other subsamples are sent to external facilities for a broad suite of analytes, including dissolved and total nutrients and carbon, cations and anions, and general chemistry. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.
