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). For the purposes of this metric, these publicly-supplied estimates are also applied and considered representative of local self-supplied water use. Residential water use reporting in the EnviroAtlas-defined study area is available through the Minnesota Geospatial Commons website. Within the Minneapolis/St Paul study area, there are 45 estimates from 2005 ranging from 42 to 167 GPD. 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.

The dasymetric data is a spatial distribution of 2010 population data into a grid of 30m cells according to land cover. The dasymetric data used in this metric is available for the contiguous US via the EnviroAtlas.

This lineage was generated by the FGDC CSDGM to 19139 transformation 1. Researched and collected community Residential Gallons Per Capita Daily (ResGPCD) estimates from the Minnesota Geospatial Commons website (gisdata.mn.gov). Within the study area, there were 45 GPDs in 2005 with an average of 78 GPD and a range of 42 to 167 GPD. 2016-07-06T00:00:00 2. Reprojected the data to GCS NAD 83, Albers Conical Equal Area. 2016-07-06T00:00:00 3. Created a FinalGPD layer. Clipped the MN layer to the study area boundary. Deleted extra fields. Created a FinalGPDs field. Used the Field Calculator to populate the FinalGPDs field with the ResGPCD_05 field. 2005 data was used since the metadata indicated it was the most current complete data. Five polygons did not have GPDs. The first four were assigned as follows: Inver Grove Heights - 68 (no 04 or 06 data available, averaged surrounding GPDs), North St Paul - 73 (based on ResGPCD_04 field), and Oak Grove - 116 (no 04 or 06 data available, based the GPD on its adjacent polygon). The final polygon was a multipart polygon for areas without a public supplier. In the absence of further data, nearby service provider GPD estimates were considered representative of self-provided/individual private wells. Split the multipart polygon into singlepart polygons. Assignments to island and edge polygons according to the surrounding/aligning GPD or the average if there was more than one GPD. On a few rare occasions, when it was excessively clear, assigned the major aligning GPD instead of the average. 2016-07-06T00:00:00 4. Verified and rasterized final GPD assignments (30m cells, snapped to the dasymetric raster). 2016-07-06T00:00:00 5. Weighted the water use by multiplying the rasterized GPDs by the dasymetrically distributed population data with the Raster Calculator. 2016-07-06T00:00:00 6. Summarized the weighted water use by block group using Zonal Statistics as Table. Divided the results to thousands of gallons per day for display in EnviroAtlas. 2016-07-06T00:00:00 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.
