This Open Geospatial Consortium (OGC) GeoPackage (.gpkg) contains water-well point features and associated tables for the state of Minnesota that have been reformatted based on a USGS profile of the OGC GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html). Additionally, the water-well records have been quality-assured to remove or nullify parts of water-well records found to be erroneous or logically inconsistent, harmonized via the assignment of common data codes in the lithologic log, and supplemented with estimates of transmissivity from the analysis of specific-capacity data. The National Water-Well Database (NWWDB) is a compilation of water-well records from state-managed databases that have been standardized to a common format for consistency across state and administrative boundaries. Water-well completion reports that are submitted to permitting state agencies by licensed drillers constitute a large source of hydrogeologic information, including the locations and distribution of water wells, construction materials and completion depths, lithologic logs, groundwater levels, and the results of pumping or aquifer tests.

To ensure the integrity of water well construction and prevent potential pollution of state groundwaters, the OWRB supervises the licensing of water well drillers and pump installers. This program is guided by comprehensive standards developed in cooperation with the Well Drillers Advisory Committee. Licensed drillers are required to submit well logs online or by mail within sixty days of the completion of a new well or plugging or reconditioning of an existing well.Well Driller Licensing Fact Sheet

Located water well records (which include UTM coordinates) and unlocated water well records (without known UTM coordinates). The estimated locations used for the unlocated wells were based on the polygon centroid values for the smallest indicated section, quarter, quarter-quarter, or quarter-quarter-quarter section (as indicated in the database) for over 250,000 water well records and for about 26,000 of the 250,000 water well records the UTM's were obtained from address geocoding using the owners address, a generally more accurate method. These data were last updated June 2019.This layer is included in the DNR Water Well Viewer webmap application.

The collection consists of records for c.5000 wells and springs in Scotland mostly lodged by drillers in compliance with the Water Act. These include data on well construction, water yields, water levels, water chemistry and well lithology. The collection is organised on the One-Inch Geological Sheet basis. Catalogues for wells in Central Scotland were published between 1963 and 1969. The BGS Single Onshore Borehole Index (SOBI) provides a partial digital index to the records.

Program Background - ADWR has two key groundwater well data sets for the state of Arizona. The 'Wells 55 Registry' corresponds with this WellRegistry GIS layer and contains all wells registered in the state. The database was originally created in 1980 to store registration information submitted by well owners and drillers. It contains over 200,000 well records. A second key well data set is also maintained at ADWR. The Groundwater Well Site Inventory (GWSI), is a statewide database that contains well locations, construction, and water level measurements for wells that have actually been located and sampled in the field (originally by the USGS and since 1990 by ADWR). The GWSI database contains over 45,000 well records. Of those, approximately 24,700 have been ‘matched’ to the Wells 55 Registry and therefore have a 'Wells 55 Registry ID'.Purpose and intended use - This data is used by both internal and external customers and is most commonly used to search for registered wells within the State.Data creation methodologies, processing, and quality - The database was originally created in 1980 to store registration information submitted by well owners and drillers. New wells are added as driller logs and reports are received.Data limitations – Please refer to ADWR Data Disclaimer. This data set contains data submitted by well owners and well drillers. Data availability is therefore limited to data provided by the public. The wells mapped to the centroid of the containing Cadastral (normally Quarter-Quarter-Quarter Section). More precise user-submitted locations are not contained in this GIS layer, however they are stored internally and are available to the public upon request for approximately 20% of the wells.Currency – Updated dailyContact – Manager, Groundwater Permitting and Wells, (602)771-8527Use limitations – Please refer to ADWR Data Disclaimer.Attribute information - programADWR program codeREGISTRY_IDUnique identifier for well record in the Wells 55 Registry database.owner_nameThe registered owner of the wellrgr_pump_dataWas water removed before 2008 or was water received in the last yearwelltypeType of wellwell_type_groupWell Type groupdlic_numMost recent driller's license numberapprovedThe earliest date in which drilling was approvedinstalledThe earliest date of well constructionwell_depthThe depth of the well in feetwater_levelThe reported depth to water in feetcasing_depthThe depth of the well's casing in feetcasing_diameterThe diameter of the well's casing in inchescasing_typeThe type of casing usedpump_typeThe type of pump usedpump_powerThe method of how the pump is poweredpumprateThe rated pumping capacity in gallons per minutetestedrateThe tested pumping capacity in gallons per minutedraw_downThe amount of water that pumping has lowered the water level in feetcompletion_report_statusStatus for reporting the completion level of the well (X-Completed, I-Incomplete, A-Abandoned, N-no report required)drill_logThe driller log's received status (X-Completed, I-Incomplete, A-Abandoned, N-no report required)well_cancelledThis indicates if the well was cancelledCadastralCadastral code indicating township, range, section location information.

This data set was derived from the Nevada Department of Conservation and Natural Resources, Division of Water Resources (NDWR) well log data base (http://water.nv.gov/Engineering/wlog/wlog.cfm). This data set was developed from a version of the data base downloaded October 26, 2005 and reflects the wells entered into the data base up to that date. The data base generally contains logs for wells drilled since 1984, however, some basins have information about older wells. No attempts were made to edit or alter the coordinate or attribute information in the data base as presented by NDWR on the date of download.

This dataset includes well logs used in the creation of the Greene hydrogeologic framework. Well logs were used from multiple sources (DEC, DOT, NWIS) and were a crucial component in generating hydrogeologic layer elevations and thicknesses. Well logs are available in their original form on GeoLog Locator (https://webapps.usgs.gov/GeoLogLocator/#!/) and provided here in the digitized form (shapefiles and feature classes), which were used in the generation of the hydrogeologic framework.

The Well Log Tracking System (WELTS) contains water well construction and lithologic information submitted to the Division of Mining, Land and Water, Alaska Hydrologic Survey by water well contractors as required per Alaska State Statute 41.08.020(b4) authority delegated to the Alaska Hydrologic Survey per Department Order 115, require of water well contractors, the filing with it of basic water and aquifer data normally obtained, including but not limited to well location, estimated elevation, well driller's logs, pumping tests and flow measurements, and water quality determinations. Additionally, per Alaska Administrative Code, Title 11 Natural Resources, Part 6 Lands, Chapter 93 Water Management, Article 2 Appropriation and Use of Water 11 AAC 93.140(a):

For a drilled, driven, jetted, or augered well constructed, the water well contractor or a person who constructs the well shall file a report within 45 days after completion with both the property owner and the department. The report must contain the following information as applicable: (1) the method of construction; (2) the type of fluids used for drilling; (3) the location of the well; (4) an accurate log of the soil and rock formations encountered and the depths at which the formations occur; (5) the depth of the casing; (6) the height of the casing above ground; (7) the depth and type of grouting; (8) the depth of any screens; (9) the casing diameter; (10) the casing material; (11) the depth of perforation or opening in the casing; (12) the well development method; (13) the total depth of the well; (14) the depth of the static water level; (15) the anticipated use of the well; (16) the maximum well yield; (17) the results of any well yield, aquifer, or drawdown test that was conducted; (18) if the water well contractor or person who constructs the well installs a pump at the time of construction, the depth of the pump intake and the rated pump capacity at that depth. (b) When the drill rig is removed from the well site, the well must be sealed with a sanitary seal and a readily accessible means provided to allow for monitoring of the static water level in the well. (c) A hand-dug well that is permanently decommissioned shall be filled by the land owner to a point 12 in above the existing ground level with well-compacted impermeable material. (d) A well, other than a hand-dug well, that is permanently decommissioned by the owner of the well must comply with the requirements of 18 AAC 80.015(e) . (e) If the department believes that an encounter of oil, gas, or other hazardous substance is likely to result from well drilling, the department will notify the Alaska Oil and Gas Conservation Commission, and the provisions of AS 31.05.030 (g) may apply. (f) The department will notify the Department of Environmental Conservation of any permanently abandoned well that may contaminate water of the state under the provisions of 18 AAC 80. (g) Information required by (a) of this section is required for any water well that has been deepened, modified, or abandoned, and for any water supply well or water well that is used for monitoring, observation, or aquifer testing, including a dry or low-yield water well that is not used. This data characterizes the geographic representation of well logs within the State of Alaska contained in the Well Log Tracking System. The shape file was developed using well location information submitted with well logs. Well locations represented by a gold star symbol, represent the approximate (centroid) location, and may represent a cluster of wells. Well locations represented by a blue circle symbol, represent wells submitted with latitude and longitude coordinates. Each feature has an associated attribute record, including a Well Log Tracking System identification number which serves as an index to case-file information. Those requiring more information regarding WELTS should contact the Alaska Department of Natural Resources Alaska Hydrologic Survey directly.

This Well Completion Report dataset represents an index of records from the California Department of Water Resources' (DWR) Online System for Well Completion Reports (OSWCR). This dataset is for informational purposes only. All attribute values should be verified by reviewing the original Well Completion Report. Known issues include: - Missing and duplicate records - Missing values (either missing on original Well Completion Report, or not key entered into database) - Incorrect values (e.g. incorrect Latitude, Longitude, Record Type, Planned Use, Total Completed Depth) - Limited spatial resolution: The majority of well completion reports have been spatially registered to the center of the 1x1 mile Public Land Survey System section that the well is located in.

This digital dataset is comprised of three separate data files that contain total dissolved solids, well construction, and well identifying information for 3,546 water wells used to map salinity in and around 31 southern and central California oil fields. Salinity mapping was done for 27 fields located in the southern San Joaquin Valley of Kern County (North Belridge, South Belridge, Canfield Ranch, North Coles Levee, South Coles Levee, Cymric, Edison, Elk Hills, Fruitvale, Greely, Jasmin, Kern Bluff, Kern Front, Kern River, Lost Hills, Mount Poso, Mountain View, Poso Creek, Rio Bravo, Rosedale, Rosedale Ranch, Round Mountain, San Emidio Nose, Tejon, Ten Section, Wheeler Ridge, and Yowlumne), 3 fields in the LA Basin of Los Angeles County (Montebello, Santa Fe Springs, and Wilmington), and 1 field in the central coast area of Santa Barbara and San Luis Obispo Counties (Santa Maria Valley). Unlike petroleum wells, water wells both within and adjacent to oil fields of interest were ...

Water well records contain details of the location, construction, and groundwater level of wells drilled on Prince Edward Island.

description: This data set is one of many developed in support of The High Plains Groundwater Availability Project and the U.S. Geological Survey Data Series report: titled Geodatabase Compilation of Hydrogeologic, Remote Sensing, and Water-Budget-Component data for the High Plains aquifer, 2011 (DS 777). This dataset contains point vector data of locations of 16,950 wells and 90,155 well log records located in areas overlying the northern High Plains aquifer in the United States. The northern High Plains aquifer underlies 61.7 million acres (96,400 square miles) in Colorado, Kansas, Nebraska, South Dakota, and Wyoming. These data were acquired from different sources and synthesized together in one dataset. Included in this dataset is a point feature class (pts_Depth2Bedrock) of elevation values and depth values to the base of the northern High Plains aquifer as well as geospatial coordinates, a table containing a digital version of well logs (tbl_LithologyAggregate) with detailed subsurface material, texture, and sorting.; abstract: This data set is one of many developed in support of The High Plains Groundwater Availability Project and the U.S. Geological Survey Data Series report: titled Geodatabase Compilation of Hydrogeologic, Remote Sensing, and Water-Budget-Component data for the High Plains aquifer, 2011 (DS 777).

The Division of Water Ground Water Database has approximately 407,000 water well records, and of those, approximately 147,000 have been field located and have x, y (UTM) coordinates. Approximately 39,000 were located based on address geocoding. The remaining records have no utms and cannot be easily utilized in a GIS format. The purpose of this dataset was to include those wells with UTM coordinates and to approximate the UTM coordinates for the others based on the most precise of county, or Township, Range, Section, quarter sections (TRS) locations available from office locating, which is effectively the centroid of the smallest known section or quarter sections; thus, increasing the amount of data available for display and analysis in a GIS format. This dataset is combination of the located water well records and the water well records for which an estimated location was able to be determined using the methods described below. This leaves less than 15,000 records with no UTM's associated with them. This dataset and associated table has selected fields from the main digital water well database that are typically needed for most research. This file is a digital geospatial point feature class of both located water well records (which include UTM coordinates) and unlocated water well records. The estimated locations used for the unlocated wells were based on the polygon centroid values for the smallest indicated county, section, quarter, quarter-quarter, or quarter-quarter-quarter section (as indicated in the database) for over 221,000 water well records and for about 39,000 water well records the UTM's were obtained from address geocoding using the owners address, a generally more accurate method (see process steps below).

These data present a ground-water inventory of existing geospatial data and other information needed to determine the extent and characteristics of the aquifers in the Tahoe Basin. Geospatial and other data include well information from various local, state, and federal agencies; geophysical surveys; and results of available ground-water and geological studies. The compilation and development of a ground-water inventory geospatial database will assist the United States Forest Service in better assessing the present and future impacts on ground-water resources within the Lake Tahoe Basin.
