Abstract:
This layer depicts aqueduct water risk results from the World Resources Institute, including water withdrawals, (total amount of water abstracted from freshwater sources for human use) consumptive use (the portion of water that evaporates or is incorporated into a product), and water supply (total blue water from natural water discharge, and available blue water which accounts for withdrawals and consumptive use).

Abstract:
This layer depicts change indicators for water supply, water demand (withdrawal and comsumptive use), water stress (the ratio of water withdrawal to supply), and seasonal variability, projected for future decades under scenarios of climate and economic growth. Time periods are centered on 2020, 2030, and 2040 for each of two climate scenarios, (RCP4.5 and RCP8.5) and two shared socioeconomic pathways, (SSP2 and SSP3).

Abstract:
This map layer contains the shallowest principal aquifers of the conterminous United States portrayed as polygons. The map layer was developed as part of the effort to produce the maps published at 1:2,500,000 in the printed series "Ground Water Atlas of the United States". This is a replacement for the July 1998 map layer called Principal Aquifers of the 48 Conterminous United States.
