On November 15th the SWRCB and USGS released a data set of water chemistry from samples collected at groundwater and surface-water sites in the San Ardo Oil Field study area, covering the time frame of March 2019–May 2021. A summary and the data can be viewed here.
Water samples analyzed for a total of 185 constituents in this data release. Samples were analyzed for (1) water-quality indicators, (2) major and minor ions, (3) nutrients, (4) trace elements, (5) volatile organic compounds (VOCs), (6) naturally-occurring radioactive material (radium isotopes), (7) geochemical and age-dating tracers, (8) dissolved organic carbon (DOC), (9) dissolved standard and hydrocarbon gases (methane through hexane), and (10) dissolved noble gases and atmospheric gases.
