Multilevel Groundwater Monitoring Systems, also referred to as Multi-Depth Groundwater Monitoring Systems, Multilevel Systems (MLSs), or Engineered Nested Wells, are engineered technologies installed in single boreholes above and/or below the water table to obtain data from different depth intervals.
Nested wells, also referred to as nested monitoring wells, are composed of multiple tubes or pipes, typically terminating with short screened intervals (2–3 ft), installed in single boreholes. Sand packs must be installed at the screen depths and seals in the borehole are constructed between the sand packs.
The Groundwater Ambient Monitoring and Assessment Program (GAMA) is an all-inclusive monitoring program for groundwater that was implemented in 2000 in California, United States. It was created by the California State Water Resources Control Board as an improvement from groundwater programs that were already in place.
Oct. 29—Efforts to map groundwater, expand research and analyze water data are getting an injection with state and federal grants. The New Mexico Institute of Mining and Technology announced ...
A project manager for the U.S. Army Corps of Engineers presented data from the monitoring wells in October to the Restoration Advisory Board, which oversees Area B groundwater clean-up activities.
Monitoring-wells are often drilled for the purpose of collecting ground water samples for analysis. These wells, which are usually six inches or less in diameter, can also be used to remove hydrocarbons from the contaminant plume within a groundwater aquifer by using a belt-style oil skimmer.
The Richland County Land Bank will have a company install monitoring wells for possible additional cleanup of water beneath the former Swan Cleaners, 165 Park Avenue West.
Monitoring wells can also be completed at multiple levels, allowing discrete samples or measurements to be made at different vertical elevations at the same map location. [19] A water well constructed for pumping groundwater can be used passively as a monitoring well and a small diameter well can be pumped, but this distinction by use is common.
