California's Groundwater Live In conjunction with the release of the latest version of California’s Groundwater (Bulletin 118) Update 2020, DWR released a new groundwater tool called California’s Groundwater Live. This new application provides powerful new tools for users to view, interact, and analyze the latest groundwater information in an open and transparent platform. California’s Groundwater Live provides the most relevant and recent groundwater information at the click of a button. The webpage also includes a series of interactive dashboards which allow users to interact and customize what groundwater data they would like to view. Users can filter the data by address, county, groundwater basin, well depth and even time period to see unique data summaries. California’s Groundwater Live has been developed for a variety of users including groundwater managers, governmental agencies, well owners, non-governmental organizations, water policy makers and members of the public interested in groundwater. From preparing for and responding to drought, to educating and empowering well owners, to helping GSAs engage with their communities to sustainably manage groundwater – this innovative platform gives users the power to explore groundwater information from a computer or smart phone.

CalGW Update 2020 - Well Completion Reports (1977–2018) This dataset includes all well completion reports submitted to the Department of Water Resources between 1977 and 2018 for newly constructed groundwater wells. This raw dataset was used to create the refined _CalGW Update 2020 - Production Well Information (1977-2018)_ dataset. This information was queried and downloaded from the Online System for Well Completion Reports (OSWCR) as of May 31, 2019.

CalGW Update 2020 - GW Quality Constituents Detected (2009-2018) CalGW Update 2020 - GW Quality Constituents Detected (2009-2018) dataset assesses statewide groundwater conditions based on a query of the GAMA database (provided by the State Water Resources Control Board). The original query searched GAMA for the maximum groundwater quality sampling result for each chemical with an established maximum contaminant level (MCL) or secondary maximum contaminant level (SMCL) from January 1, 2009, through December 31, 2018. All stations tagged as monitoring wells for permitted discharge sites, active contaminant investigations, or active cleanup sites were omitted from the dataset. The final queried dataset included more than 5 million records, more than can fit into an Excel spreadsheet, so this dataset was created summarizing water quality conditions in each hydrologic region. This summary includes the number of wells which fall into one of three categories for each chemical with an established MCL or SMCL: High (maximum recorded value above the MCL or SMCL); Medium (maximum recorded value between half the MCL or SMCL and the MCL or SMCL); Low (maximum recorded values less than half of the MCL or SMCL). This dataset was used to create Table 6-6. | XLSX | 08/11/23 | |
