Why You Should Monitor Groundwater?

What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

3 Scientific Tools to Help You Better Understand Your Water Quality

There are many ways of testing and understanding your water quality with online scientific tools and models. One such resource is the National Water-Quality Assessment (NAWQA) project run by the U.S. Geological Survey (USGS). The project, which was founded in 1991 to develop reliable information about water sources to support decisions on water quality management ...

Optimal design of groundwater-level monitoring networks

Groundwater monitoring plays a significant role in groundwater management. This study presents an optimization method for designing groundwater-level monitoring networks. The proposed design method was used in the Eshtehard aquifer, in central Iran. Three scenarios were considered to optimize the locations of the observation wells: (1) designing new monitoring networks, (2) redesigning ...

The importance of groundwater monitoring

Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

Spatiotemporal groundwater level forecasting and monitoring using a neural network–based approach in a semi arid zone

Forecasting the groundwater level (GWL) of an aquifer is one of the most important tasks in hydrogeology. Such forecasts prove vital to develop better exploitation strategies of water resources and to carry up–to–date groundwater monitoring. In this paper, an artificial neural network (ANN)–based approach, which was based on linear regression model, is presented to simulate and predict both ...

Effective Groundwater Monitoring Using Dedicated Pumping Tubes

This article describes a groundwater monitoring procedure that does not require decontamination of pumping equipment, eliminates the chance of cross contamination between wells, and uses a surface pump. Two surface pumps are described, one for water level depths less than 25 feet and one for water level depths greater than 25 feet. Install Dedicated Pumping Tubes ...

Tunnelling in Chalk: Groundwater monitoring and risk assessment

Morgan Est is constructing a tunnel to carry high voltage electricity cables between two electrical substations. The tunnel will mostly be excavated in Chalk, with some excavation occurring in the Thanet Sands. ESI was appointed as Morgan Est’s environmental consultant for the project and has managed liaison between Morgan Est, regulators and other stakeholders over the last four ...

Assessment of riverside groundwater flood risk induced by high river water levels using a numerical model and monitoring data

Large barrages have been constructed on the main rivers in South Korea to store water and mitigate fluvial flooding damage. However, the increase in water levels behind the barrages can potentially lead to a rise in groundwater levels in the riversides. The purpose of this study was to describe the effect of a barrage on groundwater levels and to test the applicability of a numerical model to ...

Monitoring groundwater resources for Municipalities - Case Study

Background The City of Tucson is located in the Sonoran Desert in southwest United States (U.S.), approximately 100 km north of the Mexico-U.S. border. Tucson Water operates more than 215 groundwater wells, covering more than 300 square miles, providing more than 37 billion gallons (140 million m3) of potable water to its 730,000 inhabitants each year. The region receives only 12 inches of ...

Groundwater levels under climate change in the Gnangara system, Western Australia

The Gnangara system is the main source of freshwater for Perth, Western Australia. However, aquifers in the region are under severe stress due to a drying climate, intensive pumping and changes in land use. The aim of this study is to apply the mean rainfall cumulative deviation and Mann-Kendall analyses at 77 monitoring bores to investigate the response of the water table to key recharge ...

Groundwater level response to hydrogeological factors in a semi-arid basin of Beijing, China

In this study, the mode of groundwater level fluctuations is analyzed by statistical approaches for 51 monitoring wells located in a semi-arid basin in Beijing from 1998 to 2013. Firstly, a geostatistical method was performed to characterize the spatial and temporal behaviors of data sets and analyze the responding mechanism of groundwater level to hydrologic features using the Geostatistics ...

Radon distribution in groundwater of Taiwan

Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up to 1,100 pCi/L. A worldwide comparison of reported groundwater radon levels was conducted. Overall radon levels in Taiwan groundwater are relatively low compared to other ...
