This layer quantifies the yearly economic value of surface water protection provided by forests and wetlands across Maryland. About half of the water supply in Maryland is sourced from reservoirs. Natural lands are exceptionally important in maintaining water quality in reservoirs, reducing the cost to treat the water to water supply standards. This analysis is focused on the five major reservoirs in Maryland, Loch Raven, Liberty, Pretty Boy, Tridelphia, and Rocky Gorge are the major water sources for residents of the densely populated Baltimore-Washington corridor. The forests and wetlands within the watersheds of these reservoirs are of unique economic value, as help to provide clean water, reducing the cost of treatment, and avoiding the cost of expensive water treatment plant upgrades to maintain quality standards. Economic values are based on a number of factors, including the average cost savings of water treatment from having trees in the watershed, the municipal price of water, and the cost avoided of having to upgrade a treatment plant to advanced treatment. The average price was found to be $1.52 per m3 of water. Almost all of this service is concentrated in four counties- Baltimore, Carrol, Howard, and Montgomery, totaling $245 of the $246 million of value yearly.

These Surface Water Supply Protection Areas delineate those areas included in 310 CMR 22.00, the Massachusetts Drinking Water Regulations, as Surface Water Supply Protection Zones:

• ZONEA: represents a) the land area between the surface water source and the upper boundary of the bank; b) the land area within a 400 foot lateral distance from the upper boundary of the bank of a Class A surface water source, as defined in 314 CMR 4.05(3)(a); and c) the land area within a 200 foot lateral distance from the upper boundary of the bank of a tributary or associated surface water body.

• ZONEB: represents the land area within one-half mile of the upper boundary of the bank of a Class A surface water source, as defined in 314 CMR 4.05(3)(a), or edge of watershed, whichever is less. Zone B always includes the land area within a 400 ft lateral distance from the upper boundary of the bank of a Class A surface water source.

• ZONEC: represents the land area not designated as Zone A or B within the watershed of a Class A surface water source, as defined in 314 CMR 4.05(3)(a). More details...Map service also available.

Wellhead protection areas are important for protecting the recharge area around public water supply (PWS) groundwater sources. A Zone II is a wellhead protection area that has been determined by hydro-geologic 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.See metadata.Also see map service.

This hosted feature layer has been published in RI State Plane Feet NAD 83. A wellhead protection area (WHPA) is the portion of an aquifer through which groundwater moves to a well. Under the Rhode Island Department of Environmental Management (DEM) Wellhead Protection (WHP) Program approved by the US Environmental Protection Agency in 1990, DEM is responsible for delineating a WHPA for each of the public wells in the state. DEM contracted with the United States Geological Survey, Dufresne-Henry Inc., and the United States Environmental Protection Agency to delineate select community stratified drift wells using analytical modeling and hydrogeologic mapping. As of August 2013, the Rhode Island Department of Health Office of Drinking Water Quality (HEALTH) is responsible for delineating the Calculated Fixed Radius WHPA's for bedrock wells, based on the pump rate of the well. Community Well - serves year-round residents; at least 15 service connections or at least 25 individuals. Examples include municipal wells and wells serving nursing homes, condominiums, and mobile home parks. DEM relied on technical input from the Wellhead Protection Program Advisory Committee in developing the delineation methodology. A mapping approach was required that was scientifically defensible, could be applied consistently across the state, and could be applied with the resources available to DEM. The delineations are based on reasonably available information regarding the hydrogeologic environment and the well characteristics. The WHPAs were delineated using the US Geological Survey quadrangle maps at a scale of 1:24000. WHPA maps are available for review at the DEM Office of Water Resources, on the DEM web page at www.dem.ri.gov/maps, and on the Rhode Island Geographic Information System webpage at www.rigis.org.

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries. Please reference the metadata for contact information.

The Integrated Report is a biennial publication on the quality of Michigan’s water resources. The Clean Water Act (CWA) requires Michigan to prepare a biennial report on the quality of its water resources as the principal means of conveying water quality protection/monitoring information to the United States Environmental Protection Agency (USEPA) and the United States Congress. The Integrated Report satisfies the listing requirements of Section 303(d) and the reporting requirements of Section 305(b) and 314 of the CWA. This 2024 draft point locations layer includes only beach locations and provides access to the preliminary dataset during the public comment period. All attainment values for specified designated use attainment categories include 2024 integrated report values.Further information, including a comprehensive 303(d) list, can be found on EGLE’s Integrated Report webpage.For questions about this data and EGLE's response, contact Molly Rippke, at RippkeM@michigan.gov.

Geologic units and geomorphic features were mapped by the California Department of Conservation Division of Mines and Geology in the early 1980's, in cooperation with California Department of Forestry and Fire Protection, the Environmental Protection Agency, California Department of Water Resources, California Department of Parks and Recreation, California Department of Water Resources, and the State Water Resources Control Board. The mapping effort covered most North Coast private forestlands and included 60 7.5' quadrangles. The maps were digitized in cooperation with the California Department of Forestry and Fire Protection in the early 90's and are available in GIS format. As part of this project, two distinct product series were created, each with unique metadata: 1) geology 2) geomorphic features. Each product series contains GIS data layers, symbology layers and AML programs for map generation, and graphics (PDF) files for each quad. The graphics files show geologic units overlain on contours, public land survey, roads, and other features that were extracted from scanned 7.5' U.S. Geological Survey topographic maps.
