Historical groundwater chemistry data compiled for the San Ardo Oil Field and vicinity, Monterey County, central California
Description
This digital dataset contains historical geochemical and other information for 255 samples of groundwater from 41 wells located within 3-miles of the San Ardo Oil Field in Monterey County, central California. Data were compiled from preexisting datasets into two separate data files described as follows: 1) a summary data file identifying each well, it's location, basic well construction, the number of chemistry samples and period of record, and data sources; and 2) a data file of geochemistry analyses for selected water-quality indicators, major and minor ions, nutrients, and trace elements, plus parameter code and (or) method, reporting level, reporting level type, and supplemental notes. A data dictionary was created to describe the geochemistry data file and is provided with this data release.
