EnviroAtlas - Memphis, TN - Domestic Water Use per Day by U.S. Census Block Group
Dataset Identification:
Resource Abstract:
As included in this EnviroAtlas dataset, the community level domestic water use is calculated using locally available water
use data per capita in gallons of water per day (GPD), distributed dasymetrically, and summarized by census block group. 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 in the EnviroAtlas-defined study area is estimated at between 81 and 100 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.
