“…The Biscayne aquifer underlies an area of about 4,000 mi 2 and extends beneath Biscayne Bay, from which its name was derived, and the Atlantic Ocean. The aquifer consists of highly permeable limestone and less-permeable sandstone and sand (Miller, 1990). The aquifer is underlain by about 600 to 1,000 ft of low-permeability, largely clayey deposits that hydraulically separate the Biscayne aquifer from the underlying Floridan aquifer system, which contains saltwater in southeastern Florida.…”

“…In these and a number of other coastal areas, ground-water withdrawals have reversed the generally seaward direction of ground-water flow, creating the potential for saltwater intrusion from the Gulf of Mexico or Atlantic Ocean or from deep parts of the aquifer that contain saltwater.

“…Water quality also was evaluated in regional studies presented in a series of hydrologic atlases of the United States (Miller, 1990;Lloyd and Lyke, 1995;Trapp and Horn, 1997) and was summarized by state in the USGS National Water Summaries (U.S. Geological Survey, 1985Survey, , 1988.

ForewordThe U.S. Geological Survey (USGS) is committed to providing the Nation with reliable scientific information that helps to enhance and protect the overall quality of life and that facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov/). Information on the Nation's water resources is critical to ensuring long-term availability of water that is safe for drinking and recreation and is suitable for industry, irrigation, and fish and wildlife. Population growth and increasing demands for water make the availability of that water, measured in terms of quantity and quality, even more essential to the long-term sustainability of our communities and ecosystems.The USGS implemented the National Water-Quality Assessment (NAWQA) Program in 1991 to support national, regional, State, and local information needs and decisions related to water-quality management and policy (http://water.usgs.gov/ nawqa). The NAWQA Program is designed to answer: What is the quality of our Nation's streams and groundwater? How are conditions changing over time? How do natural features and human activities affect the quality of streams and groundwater, and where are those effects most pronounced? By combining information on water chemistry, physical characteristics, stream habitat, and aquatic life, the NAWQA Program aims to provide science-based insights for current and emerging water issues and priorities. From 1991 to 2001, the NAWQA Program completed interdisciplinary assessments and established a baseline understanding of water-quality conditions in 51 of the Nation's river basins and aquifers, referred to as Study Units (http://water.usgs.gov/nawqa/studies/study_units.html).In the second decade of the Program (2001Program ( -2012, a major focus is on regional assessments of water-quality conditions and trends. These regional assessments are based on major river basins and principal aquifers, which encompass larger regions of the country than the Study Units. Regional assessments extend the findings in the Study Units by filling critical gaps in characterizing the quality of surface water and groundwater, and by determining water-quality status and trends at sites that have been consistently monitored for more than a decade. In addition, the regional assessments continue to build an unde...

“…Areas underlain by extensive basalt formations, therefore, can be used for drinking-water supply. Examples of such basalt formations are the Deccan Trap Aquifer in Peninsular India (Das and Ars 1971;Kulkarni et al 2000), the Columbia River Basalt Group in USA (Miller 1999), and the Golan Heights (Dafny et al 2006) and Azraq Basin in the Middle East (El-Naqa et al 2007). When such aquifers suffer depleting groundwater levels, it means that pumping rates exceed recharge rates.…”

Groundwater recharge in Pleistocene sediments overlying basalt aquifers in the Palouse Basin, USA: modeling of distributed recharge potential and identification of water pathways

2011

Groundwater levels in basalt aquifers around the world have been declining for many years. Understanding water pathways is needed for solutions like artificial drainage. Water supply in the Palouse Basin, Washington and Idaho, USA, primarily relies on basalt aquifers. This study presents a combination of modeling and field observations to understand the spatial distribution of recharge pathways in the overlying Pleistocene sediments. A spatially distributed model was used to quantify potential recharge rates. The model shows clearly that recharge predominantly occurs through non-argilic soils and soils that are not underlain by fine-grained sediments, i.e. the upper area of the watershed. A field survey was conducted to determine recharge pathways from this area. It revealed 83 perennial springs. Drillings near springs showed connection of coarse-grained layers within the fine-grained Sediments of Bovill to these springs. Such layers, with streambed-like features, act as paleo-channels. Water from one of these coarse-grained layers had a similar electrical conductivity (200 μS cm -1 ) to water from a downstream perennial spring, also suggesting the existence of a lateral conduit for deep percolation water.
