Census Block Group Data 2022

This is the feature layer. The map image layer is available [here]. The aquifer risk map is being developed to fulfill requirements of SB-200 and is intended to help prioritize areas where domestic wells and state small water systems may be accessing groundwater that does not meet primary drinking water standards (maximum contaminant level or MCL). In accordance with SB-200, the risk map is to be made available to the public and is to be updated annually starting January 1, 2021. This layer is part of the 2022 Aquifer Risk Map. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. This layer displays data available at the census block group level. Water quality risk data from the 2022 Aquifer Risk Map is summarized by block group by displaying the number of domestic wells and state small water systems per block group in "high-risk" areas. [Drought risk scores] for rural/self-supplied communities from the Department of Water Resources are displayed (drought risk scores range from 0-100, with 100 representing the highest drought risk and 0 representing the lowest drought risk). Demographic information including Median Household Income (from 2018 ACS) and race/ethnicity data per block group (B03002 from 2019 ACS five-year survey) is also displayed.
North Coast TMDL Watersheds

The boundary layers used, Hydrologic Sub-Area and Units, were obtained from CalWater v2.1.1 and were clipped to have the hydrologic sub-areas and units that have listed TMDLs in the North Coast Region. Fields were added to the data, which include Impairment and Scale. The Impairment field was added to show the impairments that were considered in the TMDLs for the specific hydrologic unit/sub-area. The scale field was added to show the different hydrologic levels with TMDLs.

San Francisco Bay Basin Plan Beneficial Uses

The California State Water Resources Control Board is currently in the process of improving the functionality and accessibility of information residing in their Water Quality Control Plans (aka Basin Plans). In order to achieve this, the data (i.e. statewide water quality objectives, beneficial uses, applicable TMDLs, etc.), are being transferred to a standardized digital format and linked to applicable surface water features. This dataset is limited to the beneficial uses data, while the water quality objectives, applicable TMDLs, etc. will be released at a later date. Data formats will include GIS data layers and numerous nonspatial data tables. The GIS layers contain hydrography features derived from a 2012 snapshot of the high-resolution (1:24000 scale) National Hydrography Dataset with added attribution. Nonspatial tables will contain various textual and numeric data from the Regional Basin and State Plans. The extent of the dataset covers the state of California and the non-spatial tables reflect the information and elements from the various plans used up to 2020. The GIS layers and associated attribution will enable the future integration of the various elements of the Basin Plans to ensure that all applicable Basin Plan requirements for a particular waterbody can be determined in a quick and precise manner across different modern mediums. The data are being managed and the project implemented by State and Regional Water Board staff using ESRI's ArcGIS Server and ArcSDE technology.

Tritium Helium Age Dating LLNL

**This data only represents the tritium-helium data, not all data presented in the paper referenced. GRIDCODE = years The state-wide data set was subjected to geostatistical analysis to reveal patterns related to recharge, groundwater residence time, and large-scale groundwater management. Variables of interest were mapped by means of kriging prediction. Noble gas derived parameters (recharge temperature, excess air, terrigenic helium-4, terrigenic helium isotope ratio and tritiogenic helium-3) were calculated using the unfractionated excess air (UA) model with a recharge elevation assumed to be the well head elevation. The local terrigenic helium isotope ratio was derived from a geostatistical interpolation and subsequently used in separating the tritiogenic helium component in each sample. In total, 1630 3H/3He ages are presented, in addition to 977 samples with less than 1 pCi/L (and assigned an age of 60 years). Young 3H/3He ages delineating areas of groundwater recharge are found along the major, perennial rivers in the Central Valley, in the forebay areas of major coastal basins dominated by managed aquifer recharge, along the northern California coast, and along the eastern slopes of the Sierra Nevada. In large portions of southeastern California, tritium-free, fossil groundwater predominates, while modern groundwater abstracted in this area is found only near distributaries of the Colorado River, which has recharged under distinctly different conditions. Tritium concentrations in the Central Valley are largely determined by the mixing of premodern (3H free) groundwater with modern groundwater (containing 3H) and not by decay of atmospheric tritium. In basins with managed aquifer recharge operations, tritium concentrations are more strongly determined by the initial tritium concentrations in specific historical recharge periods than by mixing of modern and pre-modern groundwater. Noble gas recharge temperatures range from 25 °C in the Mojave Desert to below 10 °C in the Sierra Nevada. Because of strong elevation gradients, local anomalies in groundwater recharge temperatures are difficult to distinguish on the map of noble gas recharge temperatures. However, managed aquifer recharge operations have a major impact on signatures of recharge, including patterns in stable isotopes and noble gas recharge temperatures. The depth to tritium-free groundwater typically varies between 100 and 400 ft. Several areas, including Santa Clara River Valley, San Gabriel Basin, portions of the Mojave Basin, the Los Angeles physiographic basin, and the area between Davis and Sacramento, stand out as having a very deep boundary between modern and pre-modern groundwater. On the other hand, tritium-free groundwater is found at shallow depths in the Volcanic Highlands of the North San Francisco Study Unit and in the Indian Wells area of the Basin and Range province.

Domestic Depth Groundwater Quality (Water Quality Risk)

The aquifer risk map is being developed to fulfill requirements of SB-200 and is intended to help prioritize areas where domestic wells and state small water systems may be accessing groundwater that does not meet primary drinking water standards (maximum contaminant level or MCL). In accordance with SB-200, the risk map is to be made available to the public and is to be updated annually starting January 1, 2021. The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. This layer contains summarized water quality risk per census block group, square mile section, and well point. The overall census block group water quality risk is based on five risk factors (1. the count of chemicals with a long-term average (20 year) or recent result (within 2 years) above the MCL, 2. the count of chemicals with a long-term average (20 year) or recent result (within 2 years) within 80% of the MCL, 3. the average magnitude or results above the MCL, 4. the percent area with chemicals above the MCL, and 5. the percent area with chemicals within 80% of the MCL). The specific chemicals that contribute to these risk factors are listed as well. Higher values for each individual risk factor contribute to a higher overall score. The scores are converted to percentiles to normalize the results. Higher percentiles indicate higher water quality risk. The water quality data is based on depth-filtered, de-clustered water quality results from public and domestic supply wells, collected following a similar methodology as the [Domestic Well Needs Assessment White Paper]. The methodology used to calculate the risk percentiles is outlined in the [Aquifer Risk Map Methodology].

PFAS Investigation Sites

This layer represents airports, landfills, waste water treatment plants, and chrome plating facilities the California State Water Resources Control Board staff identified as possibly being a source of Per- and polyfluoroalkyl substance (PFAS) contamination. This map is a tool for public use. On March 20, 2019 the California State Water Board sent California Water Code (CWC) Section 13267 orders requiring soil and ground water samples to sites considered to be potential sources of per - and polyfluoroalkyl substances (PFAS). These sites have facilities or activities that could be a potential source of contamination of PFAS. This does not mean that PFAS has been produced, used or discharged at these sites. The CWC Section 13267 Orders were sent to landfills and airports across the State of California. The landfill selection criteria for issuing the CWC Section 13267 PFAS Order 2019-0006-DWQ focused on active and closed landfills that accept or have accepted municipal solid waste in the past, operate under an existing Waste Discharge Requirements (WDR) Order with an active Monitoring and Reporting Program (MRP) for groundwater and leachate monitoring and sampling. The selection criteria for issuing CWC Section 13267 PFAS Order 2019-0005-DWQ focused on airports certified under Title 14, Code of Federal Regulations, part 139 (Part 139 of the FAA regulations requires the use of AFFF).Sites and locations shown in this map were identified by staff with the Division of Water Quality in the California State Water Board. Data was compiled from August through October 2019. Additional information can be found at [https://www.waterboards.ca.gov/pfas/]
Vegetation - Ciervo Panoche North [ds3126]

California Native Plant Society (CNPS) has initiated a project with partners at the Bureau of Land Management (BLM) and The Nature Conservancy (TNC) to create a detailed vegetation map in the north‐western portion of the Ciervo‐Panoche Natural Area (CPNA). The classification is fully compatible with the National Vegetation Classification System (NVCS) (FGDC 2008) and the Manual of California Vegetation (Sawyer et al. 2009), which CNPS and CDFW jointly maintain. Phase 1 of the project includes detailed vegetation mapping in the north‐western portion of the Ciervo‐Panoche Natural Area (CPNA). The project objectives during Phase 1 have included vegetation field sampling and vegetation mapping (photo‐interpretation, delineation, and attribution) in the north‐western CPNA. The vegetation map was based upon one‐meter resolution NAIP imagery taken in the summer of 2012. The minimum mapping unit (MMU) was 1 acre, with exceptions for wetland and other special types (0.5 acre MMU). In March 2015, CNPS staff conducted 189 field validation surveys across 192 pre‐selected polygons. From this data, users' and producers' accuracy was estimated. Producer’s accuracy across all types with a sample size of 3 or more was 81%, while the user’s accuracy of types with a sample size of 3 or more was 86%, meeting state standards for accuracy. Producer and user accuracy was slightly lower across all types regardless of sample size (i.e., 77% and 81% respectively), though several types had only one sample. More information can be found in the project reports, which are bundled with the vegetation map published for BIOS here: [https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/3100_3199/ds3126.zip].
