The Westbay MP system is a modular instrumentation system for multilevel groundwater monitoring acquired by Nova Metrix in 2015, the MP system consists of two parts: (1) the casing system and (2) portable probes and tools that provide a compatible data acquisition system. The Westbay casing system is designed to allow the monitoring of multiple ...
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

Aquifers of the United States Withdrawal rates from the Ogallala Aquifer.. This is a list of some aquifers in the United States.. Map of major US aquifers by rock type. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
Therefore, older data using "cataloging units" may differ from newer, higher resolution data using "subbasins".

The United States Geological Survey ((USGS)) is a publicly available source of remotely sensed hydrological data. Historical and real-time streamflow data are also available via the internet from sources such as the National Weather Service (NWS) and the United States Environmental Protection Agency (EPA). A benefit of using GIS softwares for ...
An analysis on historic water quality data from the Borrego Valley Groundwater Basin performed by the U.S. Geological Survey concluded that total dissolved solids (TDS) and nitrate in the upper level of the aquifer exceeded the water-quality thresholds for each given substance (500mg/L and 10 mg/L respectively).

In 2020, another study led by the U.S. Geological Survey laid the groundwork for this issue alongCalifornia's 1,200-mile coast, andstate toxic substances control officials have sincestarted their ...
The USGS uses the data from borehole extensometers provided by the DWR, and also utilizes information from piezometers to track changes in groundwater. [11] As of 2018, the USGS has been using large hexagonal-shaped sensor rigged to a helicopter to measure groundwater salinity and map underground aquifers in the San Joaquin Valley. These ...
