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).

Point locations of domestic wells reported to the Maine Geological Survey. This dataset is based on an original survey of well drillers in the 1970s, a voluntary well driller reporting program in the mid-1980s, and the present mandatory reporting program which relies on the submission of well information by drillers. Wells have been located using GPS coordinates submitted by the drillers, e911 address information submitted by the drillers and/or ownership data and tax records.

The U.S. Geological Survey (USGS) is providing a point feature class containing a compilation of geologic well records (n=221) obtained from: 1) previous U.S. Geological Survey groundwater investigations, 2) the U.S. Geological Survey's National Water Information System (NWIS), 3) the New York State Department of Environmental Conservation (NYSDEC) Water Well Contractor Program, and 4) the New York State Department of Transportation (NYSDOT). The wells are located within the Binghamton East 1:24,000 quadrangle of south-central Broome County, New York, 2014-2020. The shapefile was created and intended for use with geographic information system (GIS) software. A companion report, USGS Scientific Investigations Report 2021-5026 (Van Hoesen and others, 2021; https://doi.org/10.3133/sir20215026) further describes data collection and map preparation.

Private domestic well use estimates for US Census block groups were calculated using a combination of population and housing unit data from the 1990, 2000 and 2010 Decennial Censuses in conjunction with available state level domestic well completion reports for domestic wells constructed between April 1, 1990 and March 31, 2010. A detailed description of how this data was created can be found in Weaver et. al (2017).

The exported ESRI point shapefile 'allwells' was made using Arc Map 8.2 on a Win2000 pc The points were created from a download of the informix data base in June, 2002. Source of the location of the points varies. All State Plane Coordinates were entered by the applicant as the location of his well, usually from looking at a 1:24k USGS topographical map. A UTM coordinate is calculated to the center of the third quarter, or the smallest quarter of a section of land within the Public Land Survey System (PLSS). These quarters were also identified by the applicant as the location of the well. If no quarter was given, the UTM coordinate is calculated to the center of the section. The Bureau of Land Management's GCDB *.lx files were used to plot the wells in the database that are entered by section, quarter, quarter, quarter description. Points that were originally located in the State Plane Coordinate system were projected using ArcInfo to UTM Zone 13, NAD83. The final data set is projected in UTM Zone 13, NAD83. Attributes found with this coverage are downloaded from the OSE WATERS database with the exception of X-coord, y-coord which were calculated. Accuracy of well informatioin will be greatly enhanced when the entire state has been abstracted.

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 is the archived 2022 version of the Aquifer Risk Map. The most recent version is available here.This aquifer risk map is 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 raw source 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 is the final 2022 map based upon feedback received from the 2021 map. A summary of methodology updates to the 2022 map can be found here.This map displays raw source groundwater quality risk per square mile section. The water quality data is based on depth-filtered, declustered water quality results from public and domestic supply wells. The process used to create this map is described in the 2022 Aquifer Risk Map Methodology document. Data processing scripts are available on GitHub. Download/export links are provided in this app under the Data Download widget.This version was last updated December 1, 2021.Water quality risk: This layer contains summarized water quality risk per square mile section and well point. The section water quality risk is determined by analyzing the long-tern (20-year) section average and the maximum recent (within 5 years) result for all sampled contaminants. These values are compared to the MCL and sections with values above the MCL are “high risk”, sections with values within 80%-100% of the MCL are “medium risk” and sections with values below 80% of the MCL are “low risk”. The specific contaminants above or close to the MCL are listed as well. The water quality data is based on depth-filtered, de-clustered water quality results from public and domestic supply wells.Individual contaminants: This layer shows de-clustered water quality data for arsenic, nitrate, 1,2,3-trichloropropane, uranium, and hexavalent chromium per square mile section.Domestic Well Density: This layer shows the count of domestic well records per square mile. The domestic well density per square mile is based on well completion report data from the Department of Water Resources Online System for Well Completion Reports, with records drilled prior to 1970 removed and records of “destruction” removed.State Small Water Systems: This layer displays point locations for state small water systems based on location data from the Division of Drinking Water.Public Water System Boundaries: This layer displays the approximate service boundaries for public water systems based on location data from the Division of Drinking Water.Reference layers: This layer contains several reference boundaries, including boundaries of CV-SALTS basins with their priority status, Groundwater Sustainability Agency boundaries, census block group boundaries, county boundaries, and groundwater unit boundaries.

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 used for salinity mapping. Water wells within an area (buffer) of 2-miles from the administrative field boundaries, with the exception of the Wilmington oil field with a buffer of 1-mile, were used for salinity mapping. Water wells located within overlapping buffer areas of adjacent oil fields were assigned to multiple fields for the purpose of being able to map salinity on a field-by-field basis. The dataset includes total dissolved solids (TDS) analyses from 1927 to 2016. Many of the analyses represent TDS concentrations that were calculated, as part of the salinity mapping, from specific conductance (SC) in lieu of reported TDS concentrations. Approximately 30 percent of the mapped water wells are wholly or partially derived from SC. In addition, approximately 50 percent of the water wells have TDS or SC analyses from more than one unique sample date. For wells having multiple analyses TDS represents the median value for the entire period of record, irrespective of whether it is from reported, calculated, or a combination of both TDS types. This dataset also includes ancillary data in the form of bottom perforation depth, well depth, or hole depth, land-surface elevation at the well head, and well location and identifier information. Bottom perforation depth was missing for about 65 percent of all water wells used for salinity mapping and were assigned a alternative value for plotting purposes. Where available, well depth or hole depth were used in lieu of bottom perforation depth. For water wells lacking bottom perforation, well depth, or hole depth (40 percent), the bottom perforation was estimated based on screen length when available (5 percent), or when the median bottom perforation or median well depth for all wells associated with an individual field is provided as an approximation for the purpose of vertical plotting (35 percent). Summary data about each well used for salinity mapping is contained in the file called Water_Wells_Summary_Data. Detailed information about all individual TDS values including those used for determining median TDS values, are contained in the file called Water_Wells_All_Data. Data used for the development of linear regression equations for calculating TDS from specific conductance in lieu of reported TDS values are contained in the file called Water_Wells_Regress_Data.

This layer of the Map based index (GeoIndex) shows where water wells exist with data available on transmissivity, storativity and discharge/drawdown. These parameters indicate the physical characteristics of the aquifer which can relate to factors such as possible storage capacities or rate of movement of water through the rock.

New York State registered water well drillers are required to submit completion reports documenting where wells have been drilled, the specifications of those wells, and any subsequent work performed on those wells. Data regarding water wells has been collected since April 2000 as required by ECL 15-1525. Completion reports for the wells are added as they become available. Historical wells are added as the wells are mapped. Well locations are generally accurate to the parcel scale but may not represent the exact location on the property.Service layer is updated annually, and last updated 02/18/2025.For more information see https://dec.ny.gov/environmental-protection/water/water-quantity/water-well-contractor-program1.

This layer of the map based index (GeoIndex) is a map based index of the National Well Record Archive. This index shows the location of water wells along with basic information such as well name, depth and date of drilling. The index is based on the collection of over 105,000 paper records of water wells, springs and water boreholes. Geological information, construction details, water quality data and hydrogeological data may also be available for some water wells. The amount of detail held on individual sites varies widely and certain fields will have an 'unknown' value where the paper records have yet to be checked for their content. The zero values for the depth represent those for which the depth has yet to be entered into the database from the paper records. This layer is only available at specific zoom levels. Please zoom to a larger scale to interrogate the map.
