Surface Water - Chemistry Results

Description

This data provides results from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN) for field and lab chemistry analyses. The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data. Users who want to manually download more specific subsets of the data can also use the **[CEDEN Query Tool](https://ceden.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering. **NOTE:** Some of the field and lab chemistry data that has been submitted to CEDEN since 2020 has not been loaded into the CEDEN database. That data is not included in this data set (and is also not available via the CEDEN query tool described above), but is available as a supplemental data set available here: **[Surface Water - Chemistry Results - CEDEN Augmentation](https://data.ca.gov/dataset/surface-water-chemistry-results-ceden-augmentation)**. For consistency, many of the conditions applied to the data in this dataset and in the CEDEN query tool are also applied to that supplemental dataset (e.g., no rejected data or replicates are included), but that supplemental data is provisional and may not reflect all of the QA/QC controls applied to the regular CEDEN data available here.
