  1. Title: MassGIS 2003 Massachusetts Interim Wellhead Protection Areas for Community Water Supply (March 2003)

    Contributors:

    Summary: This datalayer contains polygons representing Interim Wellhead Protection Areas (IWPA) for community water supply (IWPACOM) sources as defined by the Massachusetts Department of Environmental Protection. Wellhead protection areas are important for protecting the recharge area around public water supply (PWS) wells. A Zone II is a wellhead protection area that has been determined by hydrogeologic modeling and approved by the Department of Environmental Protection's (DEP) Drinking Water Program (DWP). In cases where hydro-geologic modeling studies have not been performed and there is no approved Zone II, an Interim Wellhead Protection Area (IWPA) is established based on DEP DWP well pumping rates or default values. Certain land uses may be either prohibited or restricted in both approved (Zone II) and interim (IWPA) wellhead protection areas. In the absence of an approved Zone II, DEP has adopted the Interim Wellhead Protection Area (IWPA) as the primary, protected recharge area for PWS groundwater sources. For PWS sources that pump less than 100,000 gallons per day (GPD), the IWPA radius is proportional to the pumping rate in gallons per minute (GPM). Pumping rate is determined by DEP DWP based on one of the following methods, DWP approved pumping rate, metered data or Title 5 flow rate. The formula used for calculating the PWS well point buffer radius in feet is: Radius = ( 32 x pumping rate in GPM ) + 400 The minimum IWPA radius is 400 feet, the maximum (default) radius reached at 100,000 GPD (70 GPM) is 2,640 feet (1/2 mile). In instances where DWP pumping rate information is unavailable DWP approved default radius values are assigned based on PWS well classification. The default radius for community class PWS groundwater sources (GW) is 2,640 feet (804.6 meters). The default radius for non-community sources is 750 feet (228.6 meters) for Non Transient (NTNC) wells and 500 feet (152.4 meters) for Transient (TNC) wells. The DEP GIS Program currently [2003] maintains two statewide IWPA coverages (IWPA and IWPACOM) shared through MassGIS. Both are generated by buffering groundwater sources in the DEP Public Water Supply datalayer (PWS_DEP). The IWPA coverage contains variable width IWPA buffers for BOTH approved community and non community groundwater sources in the DEP PWS datalayer which do not have an approved Zone II. The IWPACOM coverage contains IWPAs ONLY for community PWS sources which do not have an approved Zone II.

  3. Title: MassGIS 2003 Massachusetts Approved Wellhead Protection Areas (Zone II) (Arcs) (March 2003)

    Contributors:

    Summary: This datalayer contains polylines representing internal and external boundaries of approved Wellhead Protection (Zone II) Areas for the state of Massachusetts as defined by the Massachusetts Department of Environmental Protection (DEP). Wellhead protection areas are important for protecting the recharge area around public water supply (PWS) wells. A Zone II is a wellhead protection area that has been determined by hydrogeologic modeling and approved by the Department of Environmental Protection's (DEP) Drinking Water Program (DWP). In cases where hydro-geologic modeling studies have not been performed and there is no approved Zone II, an Interim Wellhead Protection Area (IWPA) is established based on DEP DWP well pumping rates or default values. Certain land uses may be either prohibited or restricted in both approved (Zone II) and interim (IWPA) wellhead protection areas. As stated in 310 CMR 22.02, a Zone II is: 'That area of an aquifer which contributes water to a well under the most severe pumping and recharge conditions that can be realistically anticipated (180 days of pumping at safe yield, with no recharge from precipitation). It is bounded by the groundwater divides which result from pumping the well and by the contact of the aquifer with less permeable materials such as till or bedrock. In some cases, streams or lakes may act as recharge boundaries. In all cases, Zone IIs shall extend up gradient to its point of intersection with prevailing hydrogeologic boundaries (a groundwater flow divide, a contact with till or bedrock, or a recharge boundary).' DEP Zone II and Public Water Supply (PWS) data are closely linked, and DEP Zone II data should be used in association with the DEP Public Water Supply datalayer (PWS_DEP). During the approval process each Zone II is assigned a unique ID (ZII-NUM) by DEP DWP. The DEP Public Water Supply and Zone II datalayers use the ZII-NUM to link protected PWS sources to their approved Zone II. Since some PWS sources within a Zone II may not have been used to delineate that Zone II, the ZII-NUM item can be used to identify the specific wells for which a Zone II was delineated. If the DEP Public Water Supply datalayer item ZII-NUM is equal to 0 than that PWS source has no Zone II and should therefore have an Interim Wellhead Protection Area (IWPA).

  4. Title: MassGIS 2003 Massachusetts Approved Wellhead Protection Areas (Zone II) (Region Polygons) (March 2003)

    Contributors:

    Summary: This datalayer contains polygons representing approved Wellhead Protection (Zone II) Area regions for the state of Massachusetts as defined by the Massachusetts Department of Environmental Protection (DEP). Because wells tend to be clustered by the nature of the resource they tap, the Zone IIs protecting those wells will frequently overlap. As a result of this overlap, intersecting Zone IIs are composed of multiple polygons and more than one Zone II can share an individual polygon. The regions data model represents complex area features and supports overlapping or non-contiguous areas. The Zone II data layer uses the regions feature class and topological structure to manage polygonal overlap, by combining all the polygons a Zone II comprises into a single region feature subclass (see the Approved Wellhead Protection Areas (Zone II) (Polygons) layer for component polygons) . Wellhead protection areas are important for protecting the recharge area around public water supply (PWS) wells. A Zone II is a wellhead protection area that has been determined by hydrogeologic modeling and approved by the Department of Environmental Protection's (DEP) Drinking Water Program (DWP). In cases where hydro-geologic modeling studies have not been performed and there is no approved Zone II, an Interim Wellhead Protection Area (IWPA) is established based on DEP DWP well pumping rates or default values. Certain land uses may be either prohibited or restricted in both approved (Zone II) and interim (IWPA) wellhead protection areas. As stated in 310 CMR 22.02, a Zone II is: 'That area of an aquifer which contributes water to a well under the most severe pumping and recharge conditions that can be realistically anticipated (180 days of pumping at safe yield, with no recharge from precipitation).

  5. Title: MassGIS 2003 Massachusetts Public Water Supplies (March 2003)

    Contributors:

    Summary: The Public Water Supply (PWS) datalayer contains points representing the locations of Massachusetts public community surface and groundwater supply sources and public non-community supply sources as defined in 310 CMR 22.00. The public water supply systems represented in this datalayer are based primarily on information in the Massachusetts Department of Environmental Protection's (DEP) Water Quality Testing System (WQTS) database. The WQTS database is the Department's central database for tracking water supply data. The PWS datalayer also contains the locations of proposed wells that have a defined DEP approved wellhead protection area (Zone IIs). Proposed sources are not currently tracked in WQTS. Massachusetts Drinking Water Regulations (310 CMR 22.00) As stated in 310 CMR 22.02, a Public Water System means a system for the provision to the public of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days of the year. Such term includes (1) any collection, treatment, storage and distribution facilities under control of the operator of such a system and used primarily in connection with such system, and (2) any collection or pretreatment storage facilities not under such control which are used primarily in connection with such system. A public water system is either a 'community water system' or a 'non-community water system.' (a) Community water system means a public water system which serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents. (b) Non-community water system means a public water system that is not a community water system. 1. Non-transient non-community water system or 'NTNC' means a public water systems that is not a community water system and that regularly serves at least 25 of the same persons or more approximately four or more days per week, more that six months or 180 days per year, such as a workplace providing water to it's employees. 2. Transient non-community water system or 'TNC' means a public water system that is not a community water system or a non-transient non-community water system but is a public water system which serves water to 25 different persons at least 60 days of the year. Some examples of these types of systems are: restaurants, motels, camp grounds, parks, golf courses, ski areas and community centers.

  10. Title: MassGIS 2003 Massachusetts areas of critical environmental concern (July 2000)

    Contributors:

    Summary: The Areas of Critical Environmental Concern (ACEC) datalayer shows the location of areas that have been designated ACECs by the Secretary of Environmental Affairs. ACEC designation requires greater environmental review of certain kinds of proposed development under state jurisdiction within the ACEC boundaries. The ACEC Program is administered by the Department of Environmental Management (DEM) on behalf of the Secretary of Environmental Affairs. The Massachusetts Coastal Zone Management (MCZM) Office managed the original Coastal ACEC Program from 1978 to 1993, and continues to play a key role in monitoring coastal ACECs. Procedures for ACEC designation and the general policies governing the effects of designation are contained in the ACEC regulations (301 CMR 12.00). For more information about the ACEC datalayer or about the effects of ACEC designation, contact the ACEC Program at (617) 626-1394. The ACEC datalayer has been compiled by MCZM and DEM and includes both coastal and inland areas. New ACEC polygons are added periodically (1 - 2 per year) because the program continues to evaluate and designate new ACECs. This datalayer contains 25 ACECs.

  19. Title: MassGIS 2003 Massachusetts National Wetlands Inventory (Arcs) (February 2003)

    Contributors:

    Summary: This layer contains arcs representing rivers and streams for the state for Massachusetts. The National Wetlands Inventory (NWI) project, administered by the U.S. Fish and Wildlife Service, was established to generate information about the characteristics, extent and status of the Nation's wetlands and deepwater habitats. This information is used by Federal, State, and local agencies, academic institutions, U.S. Congress, and the private sector. The Emergency Wetland Resources Act of 1986 directs the Service to map the wetlands of the United States. The NWI has mapped 89% of the lower 48 states, and 31% of Alaska. The Act also requires the Service to produce a digital wetlands database for the United States. About 39% of the lower 48 states and 11% of Alaska are digitized. Approximately 50 percent of Massachusetts is available in digital format. For full details on the national mapping project visit the National Wetlands Inventory web site: http://www.fws.gov/nwi/

  20. Title: MassGIS 2003 Massachusetts Protected and Recreational Open Space (Arcs) (March 2003)

    Contributors:

    Summary: This protected and recreational open space datalayer contains polylines representing the boundaries of conservation lands and outdoor recreational facilities in Massachusetts. Conservation and outdoor recreation facilities owned by federal, state, county, municipal, and nonprofit enterprises are included in this datalayer. Privately owned lands with deeded restrictions are also included, as are lands in the Chapter 61 program. This datalayer can also be linked, through related tables, with the 1988 Statewide Comprehensive Outdoor Recreation Plan (SCORP) inventory, with facilities and activities data for recreation sites. The datalayer is paneled into 351 town coverages and significant updates are ongoing. This update effort, coordinated by MassGIS, uses volunteers from state environmental agencies, regional planning commissions, local watershed associations, town conservation commissions, municipal planning and engineering departments, local and regional nonprofits, and open space plan committees. Although the initial data collection effort for this data layer has been completed, open space changes continually and this data layer is therefore considered to be under development. Additionally, due to the collaborative nature of this data collection effort, the accuracy and completeness of open space data varies across the state's municipalities. The following types of land are included in this datalayer: Conservation land - habitat protection with minimal recreation, such as walking trails Recreation land - outdoor facilities such as town parks, commons, playing fields, school fields, golf courses, bike paths, scout camps, and fish and game clubs. These may be privately or publicly owned facilities. Town forests Parkways - green buffers along roads, if they are a recognized conservation resource Agricultural land - land protected under an Agricultural Preservation Restriction (APR) and administered by the state Department of Food and Agriculture (DFA) Aquifer protection land - not zoning overlay districts Watershed protection land - not zoning overlay districts Cemeteries - if they are a recognized conservation or recreation resource Also included for some towns are lands in the Chapter 61 program (61 = Forestry; 61A = Agriculture; 61B = Recreation). These parcel boundaries are not currently available state-wide, and may not be maintained over time, but can be useful for municipal planning purposes.
