Impact of treated wastewater on groundwater quality in the region of Tiznit (Morocco)

by IWA Publishing  (Dec. 11, 2015)

The Tiznit region has an arid to semi-arid climate. Rainfall is scarce and the reuse of wastewater for crop irrigation is common, and consequently groundwater can be contaminated by chemical and biological pollutants. A wastewater treatment plant is constructed with the aim of producing water suitable for reuse in agriculture and reducing ...

Optimal groundwater contamination monitoring using pumping wells

by IWA Publishing  (Aug. 1, 2010)

This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution ...

Major Considerations in Landfill Closure

by Agru America, Inc.  (Sep. 16, 2016)

Preparing for the closure and long-term care of a municipal solid waste landfill (MSWLF) can be an inordinate undertaking. Whether public or private, all landfills eventually reach the end of their active lifecycle. Before closure, a landfill must meet a series of criteria as determined by Subtitle D of the Resource Conservation and Recovery Act ...

Estimating Future Impacts of Groundwater Contamination on Water Supply Wells

by Solinst Canada Ltd.  (Feb. 1, 2001)

In the following sections, we provide discussion and information to supplement the Feature Article. This material could not be included in the article itself due to space limitations of the printed ...

Multifunctional Well Implemented for In Situ Remediation of Hydrocarbon Contaminations in Soil and Groundwater

Abstract A recently developed Multifunctional Well has been implemented for the remediation of subsurface contamination caused by hydrocarbon spills. Four different remediation processes can be operated within the same well. At optimal efficiency of each remediation process, successive treatment of the capillary fringes, the vadose zone, and the ...

Groundwater exploration

This is a collection of various cases where the 2D resistivity imaging method pioneered by Advanced Geosciences Inc have been successfully ...

Regional modeling of wells

by SoilVision Systems Ltd.  (Jun. 23, 2010)

The ability to represent wells in a regional three-dimensional numerical groundwater model is crucial for many modeling exercises. Such wells can either be measurement wells where groundwater levels are measured as a function of time, or wells can be pumping wells in which water is removed from the well and a drawdown cone is created in the water ...

Horizontal Wells - Technology Overview

by Groundwater Remediation Technologies Analysis Center  (Jan. 1, 1996)

Horizontal well technology has been incorporated into many current environmental remediation applications (and associated contaminants), such as in situ bioremediation, air sparging, vacuum extraction, soil flushing, free product recovery, etc. Ac cording to information reviewed, this technology is most applicable to sites with relatively shallow ...

Singleton well site

by Environmental Scientifics Group  (Apr. 30, 2010)

Client: P.R. Singleton Limited Date: 2008 – 2009 Value: £20,000 CL Voelcker was appointed by P.R.Singleton Limited to assist with the variation of permit conditions for their on-shore oil well site in West Sussex. The site is an existing oil well site for which additional capacity is required. The initial ...

by Ensia  (Oct. 22, 2014)

Solve two problems with one filter? That’s what Drinkwell aims to do. Begun through a collaboration between researchers at Lehigh University and the Bengal Engineering and Science University, the Boston-based social venture ...

Case Study - Multilevel well system improved understanding of groundwater conditions in deep aquifers

Westbay System delivered detailed data in less time and at a reduced cost CHALLENGE Characterizing the plume in a shallow  aquifer is simple, but investigating deeper  aquifers poses several challenges. SOLUTION MACTEC evaluated various monitoring  technologies and determined that  Westbay System modular ...

Impacts of energy price changes on the financial viability of agricultural groundwater wells in Tulkarm district, Palestine

by Inderscience Publishers  (Dec. 28, 2009)

Water scarcity has often been recognised as a major challenge to sustainable development and viability of the anticipated Palestinian State. Recently, after the evolution of increasing oil prices, energy has become another major challenge. Groundwater, which is the major source for Palestinians, depends greatly on diesel and electricity whose ...

Bacterial growth and biofilm formation in household-stored groundwater collected from public wells

by IWA Publishing  (Jun. 8, 2015)

The research was aimed at assessing changes in the number of bacteria and evaluating biofilm formation in groundwater collected from public wells, both aspects directly related to the methods of household storage. In the research, water collected from Cretaceous aquifer wells in Toruń (Poland) was stored in a refrigerator and at room ...

Several natural indicators of radial well ageing at the Belgrade Groundwater Source, part 1

by IWA Publishing  (Jan. 1, 2011)

Over time, the radial collector wells of the Belgrade Groundwater Source, located in the alluvial sediments of the Sava River, exhibit a decline in discharge and a reduction in operating efficiency due to well ageing. An increase in hydraulic losses at the lateral screens, due to chemical and biochemical clogging, has been identified as the ...
