Volatile organic compounds in the nation’s ground water and drinking-water supply wells

by Water Environment Federation (WEF)  (Oct. 13, 2007)

ABSTRACT Volatile organic compounds (VOCs) are produced in large volumes and are associated with a myriad of products, such as plastics, adhesives, paints, gasoline, fumigants, refrigerants, and drycleaning fluids. Widespread and long-term use of VOCs and their ability to persist and migrate in ground water raise questions about possible adverse ...

Artificial Ground-Water Recharge and Wastewater Reclamation

by American Water Works Association (AWWA)  (Sep. 1, 1975)

This article discusses economic, conservation, and research factors involved in groundwater recharge and wastewater processing. The results of a pilot-plant shallow-well injection experiment are summarized. Wastewater reclamation via artificial recharge of aquifers appears to be feasible, although engineering design for certain geologic conditions ...

Water-Quality Aspects of Ground-Water Recharge in Israel

by American Water Works Association (AWWA)  (Mar. 1, 1974)

Because of the differences in rainfall and water needs in northern and southern Israel, a method of recharging groundwater and transporting it from the north to the south was needed. The main conveyance system is the National Water Carrier, which transports surplus water from the north to the south, where the potential demand exceeds the available ...

Ground-Water Flow Patterns in Confined Aquifers and Pollution

by American Water Works Association (AWWA)  (Mar. 1, 1974)

An analytical theory has been worked out for obtaining flow patterns under steady-state conditions in horizontal aquifers of any shape pumped by a well. Part of the aquifer boundary may be impervious and the part that is not impervious may have a variable head distribution. The theory is valid for any shape aquifer any diameter of well in that ...

Modeling geothermal wells using SVHeat and SVFlux

by SoilVision Systems Ltd.  (Mar. 16, 2010)

Numerical modeling of geothermal processes has received increased attention in recent years. The process of installing geothermal heating systems in residential homes and cottages is one application of numerical models. These systems typically involve drilling between one and three wells on a particular property. Heat exchangers then act as a pump ...
