Utilizing Machine Learning for Managing Groundwater Supply
… that utilized machine learning principles. The groundwater level dynamics of two sites located at the Virginia Eastern Shore were predicted using historical groundwater level below land surface (GWLBLS) data as the endogenous variable and local pumping data as the exogenous variable. Predicting …

Rural groundwater supply for the Volcanoes National Park region, Rwanda
… that do not have access to an improved water supply should be halved by the year 2015. Rwanda is a Sub-Saharan developing country where water scarcity is an issue. This thesis presents results from a preliminary evaluation of possible groundwater supply to the village of Bisate, located in the …

The potential of renewable energy for rural groundwater supply in the Elundini Municipality
… well as from any town or major infrastructure, supplying water via traditional pipe networks is not feasible. Historically, groundwater has been the water source of choice and abstracted via the use of diesel powered borehole pumps. These pumps are however noisy, require constant maintenance and …

Development of risk-based groundwater operating rules: a case study of Siloam Village, South Africa
This study developed operating rules for groundwater supply from a probabilistic (risk-based) approach. Groundwater supply systems are often operated without relating groundwater yield/availability to demand which makes groundwater resource planning and management challenging and unpredictable. …

Estimating groundwater recharge in Jinci karst groundwater system, North China
… 25% of the world’s population relies on karst groundwater as the primary source for drinking and irrigation. However, due to the global climate change as well as population expansion, the contradictory between supply and demand of water resource becomes more and more pronounced. Karst …

Removing Soluble Organic Contaminants From Water Supplies by Lime Softening
… using a fulvic acid extracted from a local groundwater supply. In phase II the molecular characteristics of contaminants pertinent to their removal were examined by selecting a wide range of natural and synthetic organic substances and testing their removal by softening, their adsorption …

Multiple Storm Event Impacts on Epikarst Storage and Transport of Organic Soil Amendments in South-Central Kentucky
<p>The groundwater in agricultural karst areas is susceptible to contamination from organic soil amendments and pesticides. During major storm events during 2011, dye traces were initiated using sulphorhodamine-B, fluorescein and eosine in a groundwater recharge area where manure was applied to the …

The hydrogeology of the Oman Mountains
… is an arid area almost entirely dependent upon groundwater recharged by highly sporadic rainfall. Precipitation estimates are hampered by a lack of any reliable altitude-rainfall relationship. Below 700 m there is no statistically significant relationship. The isotopic composition of groundwater …

Groundwater/surface water interaction in the Raisin River watershed, near Cornwall, Ontario.
… 1994 and 1995 to understand the interaction of groundwater and surface water in the Raisin River watershed, near Cornwall, Ontario. The Raisin River lies within an agricultural region which relies heavily on groundwater use. The regional groundwater supply is predominantly from a limestone …

Evaluating residential satisfaction with an innovative dual water supply system in water sensitive urban development
… garden and outdoor irrigation with non-potable groundwater. This could save almost half of the water supplied in the residential sector, which is the biggest consumer of scheme water in most Australian cities. A major hurdle for the success of such fit-for-purpose groundwater schemes can be the …

Hydrochemical Assessment and Modelling of Groundwater Quality of an Urban Aquifer Near A Sanitary Landfill
Groundwater supply is crucial to both anthropogenic and industrial activities in Canada. In Saskatchewan, around 63 percent of municipalities rely on groundwater as their primary water supplies. Recent data suggested groundwater quality in Condie aquifer might have been compromised due to the …

Groundwater Resource Supply Augmentation: A Case Study of Dzamba and Mabulo Villages in Vhembe District Municipality, Limpopo Province, South Africa
… including a lack of sustainable water supply. Based on the location of the communities living in the area (being in the most rural areas of Limpopo province), essential service delivery, like water supply, is a severe problem. Dzamba-Mabulo Communities rely on rivers, streams, and …

Lightweight, affordable, low power solar groundwater piston pump for rural remote regions.
Solar photovoltaic powered groundwater pumping systems (SPWPS) are popular way of fetching water from boreholes in semi-arid areas in rural remote regions of most developing countries, where commercial water and electricity supply is out of reach. As the climate changes and the water table drops in …
