    Surface Water - Chemistry Results - CEDEN Augmentation

    Metadata Updated: February 23, 2026

    This dataset includes field and lab chemistry data that has been submitted to the California Environmental Data Exchange Network (CEDEN), but has not been loaded into the CEDEN database. It is a subset of the chemistry data that has been submitted to CEDEN since approximately December 2020, and supplements the data found in both the main Surface Water - Chemistry Results dataset and the CEDEN Query Tool (i.e., this augmentation data is not included in the data available from either of those sources). For consistency, many of the conditions applied to the other CEDEN data found on this portal and in the CEDEN query tool are also applied to this supplemental dataset (e.g., no rejected data or replicates are included). However, this supplemental data is provisional and may not reflect all of the QA/QC controls applied to the regular CEDEN data.

    This dataset also contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result (like the main Surface Water - Chemistry Results dataset referenced above).
