These circular buffers are used for systems where there is no model developed. Online_Linkage: http://megis.maine.gov/catalog/ SMMS_Citation_Linkages_Hyperlinked: true Description: Abstract: WELLBUFFERS contains circular buffers that represent source water protection areas for wells and surface water intakes that serve the public water supply in Maine. Well buffers are proportional to population served and/or by the type of water supply system. These buffers range from 300 to 2,500 feet in radius. Intake buffers represent a 1000 foot radius around the location of a public water supply surface water intake. PWS travel time or probabilistic source protection areas are depicted in WELLMODELS and are not included in this buffer dataset. 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.). 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 locational 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). These areas are also regulated under PL 761, requiring notice to the water supplier of locally permitted activities. Supplemental_Information: Transient Systems: The wellhead protection area (WHPA) for all Transient systems has a radius of 91.44 meters (300 ft). Community and NTNC Systems: The attributes provide the radius used for community and non-transient, non-community systems, which is calculated based on the number of customers they serve: Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: Time_of_Day: Unknown Currentness_Reference: ground condition Status: Progress: In work Maintenance_and_Update_Frequency: As needed Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -70.96951 East_Bounding_Coordinate: -66.89763 North_Bounding_Coordinate: 47.33573 South_Bounding_Coordinate: 42.98429 Keywords: Theme: Theme_Keyword_Thesaurus: Maine GIS Thesaurus-Theme Theme_Keyword: wellhead protection areas Theme_Keyword: source water protection areas Theme_Keyword: HEALTH AND SAFETY Theme_Keyword: INFRASTRUCTURE Theme_Keyword: public water supply Theme_Keyword: well buffers Theme_Keyword: health Theme_Keyword: inlandWaters Theme_Keyword: utilitiesCommunication Theme_Keyword: intake buffers Theme_Keyword: intake protection areas Place: Place_Keyword_Thesaurus: Maine GIS Thesaurus, Place Place_Keyword: Maine Stratum: Stratum_Keyword_Thesaurus: Maine GIS Thesaurus-Stratum Stratum_Keyword: human dimensions Stratum_Keyword: hydrosphere Use_Constraints: Detailed design decisions may require additional locational data.

Although this information is updated and checked for quality purposes on a regular basis, there are errors in the data. Supplies may also 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. Quantitative_Attribute_Accuracy_Assessment: Attribute_Accuracy_Value: good Attribute_Accuracy_Explanation: Most attribute data is correct, but there are some data entry errors, and some information is based on owner's recollection, or may not be current. Logical_Consistency_Report: The radius of the protection area is determined based on water system type and number of customers served. All polygons and regions have a single unique user-id number. Spatial topology meets "Data Standards for Maine Geographic Information Systems", June 2002. Completeness_Report: The data set is complete. PWS travel time or probabilistic source protection areas are depicted in WELLMODELS and not included in this buffer dataset. 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.

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.

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.
