The records are current as of June 2003, to the best of Maine Drinking Water Program (MEDWP) recorded knowledge. Data was collected by differentially corrected GPS from 1994 to 2003 and includes public water supply (PWS) wells statewide. Additional source data is available on tables that can be linked to this base data. Purpose: This dataset was developed for use by the MEDWP and other entities. Its primary purpose is to assist in management of spatial information about PWSs, in compliance with the federal Safe Drinking Water Act as Amended 1996 and 22 MRSA Chapter 601. Detailed design decisions may require additional location data. Field verification of location, ownership, and other attributes is strongly recommended. The dataset was developed by the Maine Department of Human Services, Drinking Water Program, with logistical and financial support from U.S. Environmental Protection Agency (USEPA).

Although this information is updated and checked for quality purposes on a regular basis, there are errors in the data. Supplies may be used seasonally, and may not be active. Supplies may go off-line, or be abandoned and the MEDWP may not be informed of their change in status. Additionally, the ownership of some PWSs changes over time, and should be checked for currency. Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: good Attribute_Accuracy_Explanation: Most attribute data is correct, but there are some data entry errors. Some information is based on owner's recollection, or may not be current. Logical_Consistency_Report: Data set meets "Data Standards for Maine Geographic Information Systems" (June 2002). Completeness_Report: The data set is complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: GPS data were differentially corrected using Trimble base station data. Accuracy of the well locations which were collected by GPS can range from 1 cm to over 100 meters depending on the number of satellites in view, the position of satellites in relation to each other, the strengths of the satellite signals and the distance of the base station from the GPS receiver. Geoexplorers typically provide accuracy ranges of 2 to 5 meters. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 5 Horizontal_Positional_Accuracy_Explanation: GPS data for well locations were differentially corrected using Trimble base station data.

Locations in 1991 and 1995 were collected using Trimble Pathfinder GPS Receivers. GPS is a satellite-based positioning system operated and maintained by the U.S. Department of Defense. It consists of 24 NAVSTAR satellites that orbit the earth every twelve hours at an altitude of approximately 12,600 miles, as well as ground-based monitor and upload stations, which track and monitor the satellite orbits, and a master control station. GPS receivers use the signals sent by the satellites to determine where the satellites are and then use this information to calculate the user's position on the earth. Accuracy can range from 1 cm to over 100 meters depending on the number of satellites in view, the position of satellites in relation to each other, the strengths of the satellite signals and the distance of the base station from the GPS receiver. Geoexplorers typically provide accuracy ranges of 2 to 5 meters. Locations have been mapped using the North American Datum 27 (NAD27) later converted to NAD83 in Universal Transverse Mercator (UTM) coordinate system.

There are 3 types of public water systems in Maine: Transient Systems (restaurants, boys and girls camps, campgrounds, motels, bottled water companies, etc.); Community Systems (utilities, mobile home parks, nursing homes, etc.); and Non-transient, non-community (NTNC) Systems (schools, offices, factories, etc.). All three types are included in this dataset. GPS data are collected for new sources on a continuing basis and added to the coverage periodically. GPS data are differentially corrected using Trimble base station information. GPS for many intake locations were collected from the shore and corrected for distance from shore.

This dataset has been attributed to provide general reference information in the items TYPE, RADIUS on type of public water system or feature, RADIUS of wellhead or surface water intake protection area proportional to type of system or feature depicted and BUFFER_ID for related buffer. The item PWSID, can be used to relate to existing, or build additional, detailed database information. There are three types of public water systems in Maine: Transient Systems (restaurants, boys and girls camps, campgrounds, motels, bottled water companies, etc.); Community Systems (utilities, mobile home parks, nursing homes, etc.); and Non-transient, Non-Community (NTNC) Systems (schools, offices, factories, etc.). All three types are included in this dataset. Entity_and_Attribute_Detail_Citation: The ArcView shapefile and ArcGIS geodatabase formats, commonly used for Maine GIS data, carry default identifiers and attributes that are software generated and/or important for internal recordkeeping. These are listed here to avoid repetition for every layer, and may not be repeated in the attribute descriptions and definitions of each layer. Common software generated identifiers and attributes in Maine GIS data include: FID (feature identifier), Shape (feature geometry), OBJECTID and SHAPE_lengt. In addition, most GIS formats will carry fields for PERIMETER, AREA and/or LENGTH according to feature geometry. These fields are typically available by default, with the units based on coordinate system or projection units of GIS data. Most GIS software packages also provide a means to calculate these values. It is important to test any columns containing PERIMETER, AREA or LENGTH values before using them for analysis purposes. These important values can be carried from format to format and become out-dated. Verify that the values are correct. Also, in your GIS software, please view the properties of data layers for the map units used to calculate these fields, and for the units set for display purposes.

Standard_Order_Process: Digital_Form: Digital_Transfer_Information: Format_Name: ESRI Shapefile Format_Version_Number: ARC Version 9.x Format_Specification: ArcView Shapefile Format ASCII_File_Structure: Case_Sensitive: false Format_Information_Content: MEGIS has made all vector layers, in the Maine GIS Internet Data Catalog, available in ESRI's ArcView shapefile format. A shapefile is a simple non-topological format that stores the geometry and attribute information for a set of geographic features as a set of vector (point, line, polygon) coordinates. Shapefiles draw quickly and directly in ArcView, ArcGIS, ArcExplorer. Shapefiles are a compatible data type for many other types of GIS software. Three files are fundamental to each shapefile: .shp stores the feature geometry (shape and location information); .shx stores the index of the feature geometry; .dbf a dBASE (TM) file stores the attribute information for the features. Other index files may be created to help speed analysis and query: these file formats are .sbn .sbx .ain .aix .fbn and .fbx. In addition you may find projection .prj, and metadata .xml, files associated with shapefiles. File_Decompression_Technique: Data available from this website is in .zip compressed format.
