Domestic water use, as defined in this case, is intended to represent residential indoor and outdoor water use (e.g., cooking, hygiene, landscaping, pools, etc.) for primary residences (i.e., excluding second homes and tourism rentals). The South Central Connecticut Regional Water Supply (RWA) estimates domestic water use at 50 GPD and supplies water to the western half of the study area. The U.S. Geological Survey (USGS) estimates publicly and self-supplied domestic water use at 75 GPD for the eastern half of the study area. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets). Domestic water use per census block group is being provided as a water demand metric for water resource planners and general public interest. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. completed EnviroAtlas Coordinator U.S. Environmental Protection Agency, Office of Research and Development-Sustainable and Healthy Communities Research Program, EnviroAtlas Geospatial Data Owner (919) 541-3832 109 T.W.

This lineage was generated by the FGDC CSDGM to 19139 transformation 1. Researched water use - RWA estimates domestic water use at 50 GPD for its service area. The USGS estimates domestic water use at 75 GPD for the eastern half of the study area. 2015-06-30T00:00:00 2. Applied GPDs geospatially - ArcGIS 10.2.1 was used for spatial application and analysis. Without a GIS layer for more specific application, RWA's 50 GPD was applied using city-level census block maps for Cheshire, East Haven, New Haven, North Haven, Orange, and West Haven. 2015-06-30T00:00:00 3. Applied GPDs to unassigned or null GPD blocks using census block groups - Some blocks remained without a GPD assignment after the application by city-level census block. Null GPD blocks in block groups with RWA's GPD were assigned 50 GPD. 2015-06-30T00:00:00 4. Applied GPDs to unassigned GPD blocks using census block tracts - Some blocks remained without a GPD assignment after the application by census block group. Null GPD blocks in tracts with RWA's GPD were assigned 50 GPD. 2015-06-30T00:00:00 5. Applied GPDs to remaining blocks in RWA's service area - Using the RWA website's Service Area Map for reference, 50 GPD was assigned to blocks by tract in Branford, North Branford, and Hamden, as well as the remaining western tracts. 2015-06-30T00:00:00 6. Applied GPDs to remaining null GPD blocks - The remaining null GPD blocks to the east were assigned the USGS' estimate of 75 GPD. 2015-06-30T00:00:00 7. Rasterized the GPD assignments (30m cells, snapped to the dasymetric raster). 2015-06-30T00:00:00 8. Distributed and weighted the water use - Multiplied the rasterized GPD by the dasymetric data. 2015-06-30T00:00:00 9. Summarized - Summarized by block group with Zonal Statistics. Divided the results to thousands of gallons per day for display. 2015-06-30T00:00:00 unknown 2029-02-13 This metadata was automatically generated from the FGDC Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2024-02-09T11:11:00 version of the FGDC CSDGM to ISO 19139 transform.
