More Metadata

This Water Well layer was created in March 2010 to provide an easily accessiable spatial database of water wells only. It also provides additional attribute information on Status, Depth, etc.

The original water well & pollution source layer was developed in 1988 by the County’s Environmental Health Department. Records were entered into a database from 40 years of historical paper files, which exhibited a wide range of completeness and accuracy. This was an on-going process until early 1996 at which time the layer was no longer maintained. In late 2000, the Department of Building and Development began a process of updating the layer by entering data from the permit files, which had accumulated since 1996.

The Cahuilla Valley and Terwilliger Valley groundwater basins, 9-006 and 7-026 respectively (California Department of Water Resources 2016) located approximately 25 miles southwest of Palm Springs, are the sole-source for groundwater supply for the rural disadvantaged community and two Native American Tribes, the Ramona Band of Cahuilla and the Cahuilla. The characteristics and sustainable yield of the Cahuilla Valley and Terwilliger Valley groundwater basins are not well understood and are threatened by increasing water use and potential changes in water sustainability related to climate change. Previous USGS studies of the Cahuilla-Terwilliger Valley groundwater basins defined the thicknesses and characteristics of the alluvial sediments that constitute the main water-bearing unit of the aquifer system and identified where wells completed in the underlying fractured bedrock are located (Moyle, 1976; Landon and others, 2015; Woolfenden and Bright, 1988). However, although the fractured bedrock is an important part of the aquifer system for domestic and some irrigation supply, the thickness and hydraulic characteristics of the fractured bedrock are not well understood (Landon and others, 2015; Moyle 1976). Existing gravity data identified a possible conduit for groundwater flow beneath Cahuilla Creek in the Cahuilla and Durasno Valleys (Landon and others, 2015). Electrical resistivity tomography (ERT) data was collected in August 2018 to evaluate the cross-sectional depth to bedrock underlying a narrow section of Durasno Valley, and to help select locations for groundwater monitoring wells. Data from two transects were collected perpendicular to Cahuilla Creek, and offset by approximately 600 meters (m).

Los Angeles Public Works has developed a groundwater well web viewer to provide the public with current and historical groundwater depth information throughout Los Angeles County.Purpose:To provide active wells information to the public.Supplemental Information:1. The State of California Department of Water Resources (DWR) developed the California Statewide Groundwater Elevation Monitoring (CASGEM) Program to make groundwater monitoring information available to the public through collaboration between local monitoring parties and DWR to collect groundwater elevation information statewide. The data have been compiled in the CASGEM Online System and made available to the public via the Internet with a GIS map interface. As a result, all interested parties can use the data to evaluate and monitor groundwater conditions in California.The CASGEM Online System will allow you to:• View lists of local agencies, counties and associations who have volunteered to serve as CASGEM Monitoring Entities providing groundwater data statewide• View CASGEM Monitoring Plans and Groundwater Management Plans (via hyperlink)• Search and view groundwater elevation data in tabular format• View hydrographs that show groundwater elevations for wells• Search and view groundwater monitoring well information• View mapped locations of CASGEM wells, monitoring area boundaries, and other geographic information• Measure distances between wells and size of monitoring areas and basins• Download well information, groundwater data, hydrographs and maps• Download summary reports on wells, groundwater elevations, Monitoring Entities and basin information.2. The State of California Department of Conservation developed the Division of Oil, Gas & Geothermal Resources Well Finder, which is a web viewer that allows the public to access information on oil, gas, and geothermal wells throughout the State.

In order to support science-based water resource management, a systematic effort was undertaken to characterize the nature and function of the hydrogeology in Jo Daviess County, Illinois. Jo Daviess County is a karst area. Karst is a geologically and hydrologically integrated or interconnected and self-organizing network of landforms and subsurface large-scale, secondary porosity created by a combination of fractured carbonate bedrock, the movement of water into and through the rock body as part of the hydrologic cycle, and physical and chemical weathering (Panno, S.V. et al, 2017). Springs, cover-collapse sinkholes, crevices, and caves are among the defining features of a karst terrain; each of these features is found in Jo Daviess County. Examples of these features have been located in the field and using other remotely-sensed data and characterized by scientists from the Illinois State Geological and Water Surveys (Prairie Research Institute, University of Illinois at Urbana-Champaign). For this project, groundwater samples were collected from springs and wells and analyzed for inorganic chemistry, dissolved organic carbon, stable isotopes of water, and tritium. The project objective was to initiate a karst feature database, to collect water samples from springs to determine groundwater background concentrations of major anions, cations, and field parameters, and to then characterize and group the different populations of groundwater within Jo Daviess County. This project was supported by Grant Awards F16AP00772 and F18AC00961, from the U.S. Fish and Wildlife Service to the League of Women Voters of Illinois Education Fund as well as support from the Prairie Research Institute, University of Illinois.In addition to reports created for each sampling location (containing data, photographs and interpretation) and submitted to USFWS as grantee performance reports for Grant Award F16AP00772, the publication cited below references the data and provides interpretation:Panno, S.V., W.R.

Collection of borehole geophysical logs from the Minnesota Geological Survey (MGS) Borehole Geophysical Database. This collection includes natural gamma ray, electrical, caliper, multiparameter, electromagnetic flowmeter, and video logs stored and managed at the MGS. Items in this GIS dataset have been formatted for public consumption and do not contain borehole geophysical data for any active public supply water wells flagged in the County Well Index (CWI) database. If available, links to PDF and LAS files for logs are included in the attribute table.Attribute names with (CWI) denote attributes pulled directly from the CWI database.The Borehole Geophysical Database includes both logs generated by the MGS and those generated by third-parties and donated to the MGS collections.BGD collections include the following:Gamma logs (natural gamma radiation and typically single point resistance [abbrev. "RES" on logs] and spontaneous potential [abbrev. "SP" on logs])Electrical logs (single point resistance and/or spontaneous potential)Caliper logs (borehole diameter)Multi-parameter logs (natural gamma radiation, fluid resistivity, spontaneous potential, temperature, normal resistivity, single point resistance, and specific conductivity)Electromagnetic (EM) flowmeter logs (flowmeter, fluid resistivity, and temperature)Including those collected during ambient, injected, and pumping conditionsVideo logs (borehole video recordings)This web map serves to make the BGD collections publicly accessible, providing users with direct access to digital PDF and LAS (Log ASCII Standard) copies (if available) of any log, and was made possible through funds provided by the United States Geological Survey National Geologic and Geophysical Data Preservation Program (NGGDPP) (Award Nos. G15AP00105 and G17AP00089) and cost-shared with matching funds from the MGS. Click here to visit the BGD web map landing page.Each layer also includes unit stratigraphy codes representing the first and last bedrock unit (if bedrock is present) encountered during logging as interpreted by MGS geologists in the days following data collection. These interpretations are considered historical data and may not represent the most up-to-date stratigraphic interpretation for any borehole. Users should always refer to the stratigraphic interpretations provided in the County Well Index for any particular water well record. Direct links to corresponding County Well Index water well log records and well stratigraphy records are included.Also, please note the following:Due to security concerns, wells supplying public water systems that are currently active are not displayed on the BGD web map.The location of each borehole geophysical record is based on the corresponding location data provided by the County Well Index. Any borehole geophysical record whose unique number does not match a corresponding water well unique number in the County Well Index is not shown geospatially but its record is still contained within the feature layer attribute table.The borehole geophysical log header information included in the PDF and LAS files is considered historical data. The static header information may not match the current information in the layer attributes. For the most up-to-date location and construction information, refer to the County Well Index.To learn more about how the MGS uses borehole geophysical logs to distinguish hydrostratigraphic units in Minnesota’s Paleozoic bedrock and to better define the hydrogeologic framework see Hydrogeology of the Paleozoic Bedrock in southeastern Minnesota, Minnesota Geological Survey Report of Investigations 61 (Runkel and others, 2003).

These well locations were derived from historical mine maps known as the WPA, Ksheet, and Hsheet collections. These locations are provided for informational purposes only and should not be sole means of decision making and are in no way a substitute for actual on the ground observation. In 1859, the United States’ first commercial oil well was drilled in Venango County, Pennsylvania. In the 150 years subsequent to this, an unknown number of oil and gas wells have been drilled in the state. A current estimate by the Independent Petroleum Association of America places that number at approximately 325,000. Of those 325,000 wells, over 200,000 are still unaccounted for. As these wells are found and verified, they are cataloged in the Department of Environmental Protection’s (DEP) Abandoned and Orphan Well database to facilitate plugging. There are currently over 8,200 wells listed in this database (2013). With so many unknown oil and gas wells scattered across Pennsylvania and the environmental threats that they pose, identification remains a vital component of DEP’s Oil and Gas Program. Currently, the DEP, Office of Active and Abandoned Mine Operations is involved in many projects dealing with historic and active mine map restoration and geo-referencing. These maps, which vary in age, not only contain information on historic mine locations, but also oil and gas locations. Through collaboration between the Bureau of Mining Programs and the Bureau of Oil and Gas Planning and Program Management, potential oil and gas well locations were assembled using three mine map collections. These collections include the WPA mine map collection, Ksheets collection, and the Hsheets collection. From these sources, over 30,000 potential historic oil and gas well locations were derived. The Bureau of Oil and Gas Planning and Program Management is constantly looking for historic sources to help locate oil and gas wells in the state that remain unaccounted for. This particular dataset was created using georeferenced mine maps of various/unknown accuracy and various/unknown coordinate systems to various base maps, including but not limited to USGS topographic maps and PAMAP aerial photography. The locations were then digitized using the georeferenced mine maps. These locations are provided for informational purposes only and should not be sole means of decision making and are in no way a substitute for actual field observations.

A County Geologic Atlas (CGA) project is a study of a county's geology, and its mineral and ground-water resources. The information collected during the project is used to develop maps, data-base files, and reports. This same information is also produced as digital files. The map information is formatted as geographic information system (GIS) files with associated data bases. The maps and reports are also reproduced as portable document files (PDFs) that can be opened on virtually any computer using the free Acrobat Reader from Adobe.com. All of the digital files for the CGA's can be downloaded from the University of Minnesota Digital Conservancy. The majority of the files can also be viewed and queried through the use of this Story Map.Atlas information is commonly used in planning and environmental protection programs, as an educational resource, and by industries involved in water and mineral resources. It represents a comprehensive, detailed compilation of geologic data and interpretations within a county. The distribution and character of geologic materials determine how and where water enters the earth, and where it is stored in aquifers that can supply our needs. Geologic maps are a key element in delineating those flow paths and in relating land use to water quality. The atlas also provides a framework and terminology to support more detailed, site-specific studies. The records of water wells drilled in the area are an important source of data for constructing the maps and for understanding the distribution and use of ground water in the county. A data base of the information from those wells is one of the atlas products, and it can be queried with the GIS files to yield valuable insights for managing the ground-water resource.The atlas is also useful to non-professionals who simply wish to learn more about the geology of the county. It is a one-stop, comprehensive collection of information in a variety of forms and styles that should be useful to anyone with an interest in earth science or the county.The geologic data and maps are produced and distributed by the Minnesota Geological Survey (MGS) as Part A of an Atlas. The Minnesota Department of Natural Resources follows with an investigation of the quantity, quality, and pollution sensitivity of ground water. Their products are distributed as Part B of the atlas, at a later date. If necessary, a report with additional information that was not possible to include on the limited space of the printed maps is produced by MGS as Part C of, or included as a supplement to, an atlas. The Atlas CD or DVD, which is available online at the Digital Conservancy, includes all the atlas products developed by the Minnesota Geological Survey.

This feature class is updated every business day using Python scripts and the Well Log database. Please disregard the "Date Updated" field as it does not keep in sync with DWR's internal enterprise geodatabase updates. This feature class contains the location and site attributes of drilled wells in Nevada. Licensed well drillers submit well logs (reports) to NDWR. This information is entered into the Well Log database in SQL Server. Latitude and Longitude coordinates are displayed in GIS format for convenience in identifying wells. Two additional fields are calculated for specific capacity and transmissivity. Specific capacity is yield divided by drawdrawn. Transmissivity is specific capacity times 267. If yield or drawdown fields are blank, specific capacity is blank.You may search for well reports at https://tools.water.nv.gov/WellLogQuery.aspxNevada Administrative Code for Underground Water and Wells

The Division of Water Rights and Utah Geological Survey (UGS) began a cooperative program to analyze water well cuttings and prepare a geologic log for selected wells in 1995. Samples are taken at regular drilling intervals by water well drillers. The samples are analyzed by UGS and a geologic log and sample analysis log is created.

More Metadata The data set of water wells and pollution sources in the county that have been identified and assigned a unique SITE-ID number. Drain fields are independent, private sewage disposal systems denoted with PSSD. Cemeteries are included as a potential groundwater and soil pollution source. Within this data set, the majority of wells are individual potable water wells and the majority of pollution sources are individual sewage disposal (septic/drain field) systems. Other types of wells and pollution sources, like cemeteries, also exist in the data and are listed and explained in the data dictionary. Note that all identified pollution sources are not necessarily causing pollution but, rather, can be simply a potential source of pollution. Information for wells comes primarily from State Groundwater Well Completion (GW2) forms completed by well drilling contractors and varies in accuracy and completeness. Information for pollution sources comes primarily from the Health Department permitting and inspection process and/or date of discovery from field verification.
