Surface Water - Toxicity Results

Surface water toxicity data from the California Environmental Data Exchange Network (CEDEN). CEDEN is the California State Water Board's data system for surface water quality in California, and seeks to include all available statewide data (such as that produced by research and volunteer organizations). Data in CEDEN include field, sediment and water column data collected from freshwater, estuarine, and marine environments. Examples of data in CEDEN come from laboratory, physical and biological analyses and include data types associated with chemical, toxicological, field, bio-assessment, invertebrate, fish, and bacteriological assay assessments.

The data resource "Surface Water Toxicity" contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result.

Zip files are provided for bulk data downloads (in csv or parquet file format), and developers can use the API associated with the "Surface Water Toxicity" (csv) resource to access the data. Example R code using the API to access the data can be found here.

Users who want to manually download more specific subsets of the data can also use the CEDEN query tool, at: https://ceden.waterboards.ca.gov/AdvancedQueryTool
