WASSI Future Change in Water Supply Stress Index 1991-2010 WaSSI (Water Supply Stress Index) predicts how climate, land cover, and human population change may impact water availability and carbon sequestration at the watershed level (about the size of a county) across the lower 48 United States. WaSSI users can select and adjust temperature, precipitation, land cover, and water use factors to simulate change scenarios for any timeframe from 1961 through the year 2100. Simulation results are available as downloadable maps, graphs, and data files that users can apply to their unique information and project needs. WaSSI generates useful information for natural resource planners and managers who must make informed decisions about water supplies and related ecosystem services...

This area is underlain by a thick wedge of sedimentary deposits that form a complex groundwater system in which the sands and gravels function as confined aquifers, and the silts and clays function as confining units. These confined aquifers of the NACP constitute a major source of water for public and domestic supply for the nearly 27 million people living in the region, as well as being important source of water for industrial and agricultural purposes. Increases in population and changes...

All or part of 24 states within this glaciated region were included. The U.S. Safe Drinking Water Act defines a "public water system" as an entity that provides water for human consumption through pipes or other constructed conveyances to at least 15 service connections or serves an average of at least 25 people for at least 60 days out of the year (United States Environmental Protection Agency, 1998). Water may be used for several purposes such as for commercial, industrial, and residential use, or may be used only for one specific purpose such as for residential use.

Water-resource managers and policy makers will need accurate water-use data for regional water-supply planning including infrastructure investment, conservation, and cost-recovery strategies. Quantifying public-supply and self-supplied industrial water use and relating the use to effects on -water resources and natural hydrologic systems; is important for the public and policy makers. This dataset includes public-supply water-use and self-supplied industrial water-use information for the State of Tennessee in 2010. Public supply...

Many riparian systems have undergone dramatic alteration over the last 50 - 100 years, exacerbating the conflicts between resource use and biodiversity protection. One of the most visible changes that is in part due to altered flow regimes is the establishment of invasive plant species in riparian ecosystems. The highest priority invasive riparian plant is the Eurasian tree/shrub, tamarisk (or saltcedar, Tamarix spp.) the third most abundant...

Each flow path began in the aquifer outcrop area (shallow well depths) and ended at public supply wells (deep well depths) in Memphis, TN in the confined parts of the aquifer.

Among the most controversial, and potentially most effective tamarisk control approaches is the introduction of the tamarisk leaf beetle, Diorhabda carinulata. The beetle has spread throughout virtually the entire upper Colorado River Basin, established major populations at Lake Mead in 2012, and is now poised to expand into the lower Colorado River Basin concordant with documented evolutionary change in beetle developmental response that may enable survival in southern regions.

As a result of continuing population growth, moderate to extreme droughts and floods, demands for competing water resources, and aging infrastructure, the evaluation of ongoing water-resources issues has become increasingly important to Federal, State, and local water-resources managers. In order to assist local decision makers in the watershed, the U.S. Geological Survey (USGS) began a study in 2013 to document groundwater and surface-water withdrawals. Estimates of water use for public supply were projected in 10-year increments through 2040 and were based on 2010 public supply water data and population projections for 2020...

Although projections of water-use estimates are subject to a variety of contingencies, ranging from natural disasters such as droughts and floods to economic booms or disruptions, they provide a basis for planners to evaluate the adequacy of water resources to meet future needs. During 2007, the State of Tennessee experienced a drought that limited water supply to several of the utility systems. As a result, the U.S. Geological Survey (USGS), in cooperation with the Tennessee Department of Environment and Conservation,...
