  • Alternative water supply and treatment solutions in Durban (SA)

    As a result of persistent drought conditions in South Africa a customer (an international consumer goods producer with a production facility in Durban) experiences the pressure of limited availability of water. The ever dropping dam levels currently result in higher risk for intermittent water supply resulting in unplanned and forced production stops in case no water is available. Aquest Colsen ...

  • How Reliable Are Your Groundwater Level Measurements

    Over the past few years, Eijkelkamp Soil & Water has gained extensive experience in the management of groundwater level measurement networks. This experience also serves as a foundation for our ongoing efforts to develop and enhance the collected data. For example, in the course of our activities, we have observed a growing discrepancy between manually-collected measurement data and ...

  • Groundwater level forecasting using SVM–PSO

    The prediction of groundwater levels in a basin is of immense importance for the management of groundwater resources. In this study, support vector machines (SVMs) is used to construct a ground water level forecasting system. Further the proposed SVM–PSO model is employed in estimating the groundwater level of Rentachintala region of Andhra Pradesh in India. The SVM–PSO model with various input ...

  • Groundwater Remediation

    Groundwater remediation or clean-up is required when concentrations of contaminants exceed or are expected to exceed predetermined levels for the type of resource that is impacted (Grossman et.al., 2008). For example, lead levels in drinking water should not exceed the EPA action level of 0.015 mg/L. What caused the high levels of lead? How can the lead be removed from the aquifer? (Grossman ...

  • Assessing climate change impact on root-zone water balance and groundwater levels

    The present study employs regional climate model projections for assessing the impact of root-zone water balance and groundwater levels using crop and groundwater models. The projections from Hadley Regional Model 3 (HRM3) for A1B scenario showed an increase in temperature and rainfall (RF) of 1.8 °C and 328 mm, respectively, during mid-century (MC) (2021–2050) for Indian central Punjab. The ...

  • Nutrient mobilisation and losses related to the groundwater level in low peat soils

    The changes in dissolved organic carbon (DOC), N-NO3, N-NH4 and P-PO4 concentrations in response to fluctuations in the groundwater table were investigated in the peatlands of Biebrza National Park and some of its surrounding sites. The lowering of the groundwater table during summer time was accompanied by an increase in P-PO4 and N-NH4 concentrations, and in some cases they were exceptionally ...

  • Researchers discover high uranium levels in south India groundwater

    The uranium isotopes during their course of their disintegration decay into other radioactive elements and eventually decay into stable lead isotopes. The cause of environmental concern is the emanation of beta and gamma radiation during disintegration. The present study tends to estimate uranium in groundwater trapped in granite and gneiss rocks. Besides, the study aims at estimating the ...

  • Groundwater level probabilistic forecast and the effects on designing depressed freeways

    Assessing a cautionary groundwater level in roadworks is crucial in minimizing the risk of flooding and of hydraulic uplift throughout the entire period of road operation. A Monte Carlo probabilistic forecast of groundwater rise in the next 50 years from today was performed in order to determine the interaction between groundwater levels and a depressed freeway to be built ...

  • 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 Forecasting in a Shallow Aquifer Using Artificial Neural Network Approach

    Forecasting the ground water level fluctuations is an important requirement for planning conjunctive use in any basin. This paper reports a research study that investigates the potential of artificial neural network technique in forecasting the groundwater level fluctuations in an unconfined coastal aquifer in India. The most appropriate set of input variables to the model are selected through a ...

  • 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 ...

  • Keeping/ reconstituting groundwater

    In urban areas the rainwater often is (was) fast drained away. That leads to a shift in the water balance, infiltration and evaporation declined compared with the natural conditions. Caused by the missing infiltration, the groundwater level decline, which could have irreversible consequences for ecosystems like wetlands, lakes or rivers (because of missing low flow runoff). ...

  • Groundwater data network interoperability

    Water data networks are increasingly being integrated to answer complex scientific questions that often span large geographical areas and cross political borders. Data heterogeneity is a major obstacle that impedes interoperability within and between such networks. It is resolved here for groundwater data at five levels of interoperability, within a Spatial Data Infrastructure architecture. ...

  • Groundwater management in China

    After introducing groundwater development and other issues, the paper analyzes China's groundwater management system and its problems, and provides suggestions for improving the system. Increasing water demand since the 1970s has resulted in severe groundwater overdraft, water level decline and water quality degradation in China, but the current management system is not able to provide an ...

  • Soil and groundwater remediation

    At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...
