Water Quality - Effluent - Electronic Self-Monitoring Report (eSMR) Data

Wastewater discharges are regulated by the Water Board. Those regulated are generally required to submit Self-Monitoring Reports to the State or Regional Water Board. Some dischargers submit their reports through the electronic Self-Monitoring Report (eSMR) module of the California Integrated Water Quality System (CIWQS). Generally these are for discharges into surface waters regulated by an individual National Pollutant Discharge Elimination System (NPDES) permit, though other dischargers may be included in this dataset as well. This dataset are the monitoring results that have been submitted as data points after the submitters have been approved for electronic submittals (i.e. after the "all electronic date").

Note that this dataset does not include records where the sampling date falls outside of the years shown below. The excluded records include: records where the sampling date is missing, records where the sampling date is invalid (e.g., records with sampling dates in the future or unreasonably far in the past), and records for samples taken prior to year 2006. The excluded records represent approximately 0.1% of all records in the complete eSMR dataset.
Surface Water - Sampling Location Information

<p>Information about sampling locations for data from the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN). This set of station/project combinations can be combined with other data sets from CEDEN to provide more information. 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, bioassessment, invertebrate, fish, and bacteriological assay assessments.</p>

Seismic Compliance Data By County for General Acute Care Hospitals

Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a Structural Performance Category (SPC) which measures the probable seismic performance of building structural systems. Building structural systems include beams, columns, shear walls, slabs, and foundations. SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by January 1, 2020, unless an approved extension has been granted, and all SPC 2 buildings to be removed from providing general acute care services by January 1, 2030. A hospital facility meets the January 1, 2030 requirements if all the general acute care buildings on campus are SPC and NPC compliant. 2030 compliant SPC ratings are either SPC 3, 4, 4D, or 5. 2030 compliant NPC ratings is NPC 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.
Seismic Deadline Extensions Granted for California Hospitals

This dataset lists the General Acute Care (GAC) Hospitals that have been granted extensions for seismic compliance. Note that facilities that currently have extension requests under review are not included in this table. Extensions are sorted by County and by hospital building.  To link the HCAI IDs with those from other Departments, like CDPH, please reference the "Licensed Facility Cross-Walk" Open Data table at https://data.chhs.ca.gov/dataset/licensed-facility-crosswalk.
Hospital Building Data

Provides basic information for general acute care hospital buildings such as height, number of stories, the building code used to design the building, and the year it was completed. The data is sorted by counties and cities.  Structural Performance Categories (SPC ratings) are also provided.  SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. Where SPC ratings have not been confirmed by the Department of Health Care Access and Information (HCAI) yet, the rating index is followed by 's'. A URL for the building webpage in HCAI/OSHPD eServices Portal is also provided to view projects related to any building.
Surface Water - Benthic Macroinvertebrate Results

Data collected for marine benthic infauna, freshwater benthic macroinvertebrate (BMI), algae, bacteria and diatom taxonomic analyses, from the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN). Note bacteria single species concentrations are stored within the chemistry template, whereas abundance bacteria are stored within this set. Each record represents a result from a specific event location for a single organism in a single sample.

Continuous Groundwater Level Measurements

DWR  continuous groundwater level measurements contains continuous time-series data from automated recorders at sites operated by the Department of Water Resources. Readings are taken at 15-minute to one-hour intervals. Some of the readings are relayed to the California Data Exchange Center. However, most of the monitoring sites are visited once every month or two, when readings are off-loaded from data recorders, then finalized and published. Wells monitored for this dataset are located within Butte, Colusa, Glenn, Mendocino, Modoc, Sacramento, San Joaquin, Shasta, Siskiyou, Solano, Sutter, Tehama, Yolo, and Yuba Counties.

Water-level measurements are the principal source of information about changes in groundwater storage and movement in a basin, and how these are affected by various forms of recharge (e.g., precipitation, seepage from streams, irrigation return) and discharge (e.g., seepage to streams, groundwater pumping).

Water-level monitoring involves "continuous" or periodic measurements. Continuous monitoring makes use of automatic water-level sensing and recording instruments that are programmed to make scheduled measurements in wells. This provides a high-resolution record of water-level fluctuations. Resulting hydrographs can accurately identify the effects of various stresses on the aquifer system and provide measurements of maximum and minimum water levels in aquifers. Continuous monitoring may be the best technique to use for monitoring fluctuations in groundwater levels during droughts and other critical periods when hydraulic stresses may change at relatively rapid rates, or when real-time data are needed for making water management decisions [see usgs reference](https://ca.water.usgs.gov/sustainable-groundwater-management/groundwater-levels-california.html).

WDL Ground Surface Displacement - Land Subsidence Monitoring

Borehole extensometers are a more site specific method of measuring land subsidence. These instruments consist of a pipe or cable anchored at the bottom of a well casing. Pipe or cable extend from the bottom of the well, through geologic layers susceptible to compaction, to the ground surface. The pipe or cable is connected to a recorder that measures the relative distance between the bottom of the bore hole to the ground surface. These instruments are capable of detecting changes in land surface elevation to 1/100th of a foot. When land subsidence and water depth monitoring activities are paired together, hydraulic and mechanical properties of the aquifer system can be determined. DWR monitors 11 extensometers in the Sacramento Valley.

California WIC Authorized Product List

This dataset represents the list of CA WIC authorized food items identified by food category and subcategory. Each item is uniquely identified by a Universal Product Code (UPC) or Price Look-Up code (PLU) for WIC electronic benefit transfer (EBT). The WIC Authorized vendors use the CA Authorized Product List (APL) to transact WIC food items at cash registers. The APL plays a crucial role in supporting WIC EBT purchases. WIC EBT requires vendor systems to maintain the APL to match the scanned food items' UPCs to ensure they are on the APL. The food items identified by UPC and PLU can be found in the data files below. When you download the files, Excel may prompt you to automatically format the data. If prompted, you may want to hit ‘Don’t Convert’ so that Excel leaves the data as is without any formatting or data conversions.

The Women, Infants and Children (WIC) Program is a federally-funded health and nutrition program that provides assistance to pregnant women, new mothers, infants, and children under age five. WIC helps California families by providing food benefits to individual participants based on their nutritional need and risk assessment. The food benefits can be used to purchase healthy supplemental foods from approximately 3,800 WIC authorized vendor stores throughout the State. WIC also provides nutritional education, breastfeeding support, healthcare referrals, and other community services. Participants must meet income guidelines and other criteria. Currently, 84 WIC agencies provide services monthly to approximately one million participants at several hundred sites in local communities throughout the State.
