Aerial view of Phase II of the McCook Reservoir under construction in 2023. The Tunnel and Reservoir Plan (abbreviated TARP and more commonly known as the Deep Tunnel Project or the Chicago Deep Tunnel) is a large civil engineering project that aims to reduce flooding in the metropolitan Chicago area, and to reduce the harmful effects of flushing raw sewage into Lake Michigan by diverting ...
These Wellhead Protection Programs must specify the duties of State agencies, local governmental entities, and public water supply systems to develop and implement wellhead protections. Identification of the area that needs wellhead protection must be based on the hydrologic and geologic information on groundwater flow, recharge, and discharge.
The National Ground Water Association (NGWA), headquartered in Westerville, Ohio, is a membership-based nonprofit organization.. Founded in 1948, the organization is composed of United States and international groundwater professionals in four membership divisions: water well contractors, scientists and engineers, manufacturers, and suppliers.
A wellhead protection area is a surface and subsurface land area regulated to prevent contamination of a well or well-field supplying a public water system. This program, established under the Safe Drinking Water Act (42 U.S.C. 330f-300j), is implemented through state governments.
Groundwater banking is a water management mechanism designed to increase water supply reliability. [1] Groundwater can be created by using dewatered aquifer space to store water during the years when there is abundant rainfall .
Sustainable groundwater management: the management and use of groundwater that can be maintained without causing an undesirable result. Undesirable results include any of the following: Persistent lowering of groundwater levels; Significant and unreasonable reductions in groundwater storage; Significant and unreasonable saltwater intrusion
The amount of groundwater right is based on the size of the surface area where each landowner gets a corresponding amount of the available water. Once adjudicated, the maximum amount of the water right is set, but the right can be decreased if the total amount of available water decreases as is likely during a drought.
MODFLOW simulation. MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow equation.The program is used by hydrogeologists to simulate the flow of groundwater through aquifers.
