  • Case study - Low-flow groundwater sampling on a nuclear site

    Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...

  • Tailings paste disposal – more than water recovery

    The minerals industry has faced increasing pressures in recent years in the management of tailings streams. Environmental, economic and other factors have led many minerals producers to explore the technology of making and using “paste.” With the increasing number of installations worldwide, this technology has proved to not only be industry accepted, but economically advantageous. ...

  • Case study -Norfolk County Council tackle groundwater contamination with low-flow

    Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. Elizabeth Guilford of Norfolk County Council hired the low flow kit from Geotech and used it on a Norfolk CC landfill where leachate contamination of groundwater was suspected. Samples taken at 2m intervals close to elevation of the suspected ...

  • Determinants of water purchases by pistachio producers in an informal groundwater market: a case study from Iran

    Market-based water allocation systems have the potential to ensure that scarce water will flow to the user who earns the highest marginal value from that water. However, the number of recorded instances where water supply problems are solved by market-based systems remains limited. This study attempts to identify the decisive factors that motivate farmers’ participation in informal spot water ...

  • Assessment of groundwater quality using geographical information system (GIS), at north-east Cairo, Egypt

    The present investigation has been conducted to delineate the hydrogeochemical and environmental factors that control the water quality of the groundwater resources in the north-east of Cairo. A complementary approach based on hydrogeochemistry and a geographical information system (GIS) based protectability index has been employed for conducting this work. The results from the chemical ...

  • Role of hydrogeochemical process in increasing groundwater salinity in the central Godavari delta

    Groundwater salinization is an ever increasing problem in coastal aquifers due to seawater intrusion resulting from excessive groundwater withdrawals, lithological conditions of the aquifer and industrial and agriculture pollutant loads. Identification of salinity sources is challenging and a prerequisite for the protection of coastal fresh water aquifers. The present aim of the study is to ...

  • Pharmaceutical occurrence in groundwater and surface waters in forests land‐applied with municipal wastewater

    The occurrence and fate of pharmaceutical and personal care products in the environment are of increasing public importance due to their ubiquitous nature and documented effects on wildlife, ecosystems, and potentially humans. One potential, yet undefined, source of entry of pharmaceuticals into the environment is via the land application of municipal wastewater onto permitted lands. The ...

  • Groundwater and stream E. coli concentrations in coastal plain watersheds served by onsite wastewater and a municipal sewer treatment system

    The goal of this study was to determine if onsite wastewater treatment systems (OWS) were influencing groundwater and surface water Escherichia coli concentrations in a coastal plain watershed. Piezometers for groundwater monitoring were installed at four residences served by OWS and five residences served by a municipal wastewater treatment system (MWS). The residences were located in two ...

  • Electrochemical degradation of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in groundwater

    Perfluoroalkyl and polyfluoroalkyl substances (PFASs) represent hazardous pollutants and are frequently detected in the environment, e.g. in contaminated groundwater. PFASs are persistent to biodegradation and conventional oxidation processes such as ozonation. In this study electrochemical degradation of PFASs on boron-doped diamond (BDD) electrodes is demonstrated. Experiments were performed ...

  • What Effect Does E-Waste Have On Groundwater?

    Groundwater is one of the most precious resources on Earth. Its yields supply water to nearly every community in the country, and without it, most of us would be driven to drastic measures to accommodate drought conditions. In fact, that very situation is happening in communities across the nation. As groundwater is increasingly negatively ...

  • Case study - Multilevel sampling and monitoring, Maryland, USA

    Challenges Volatile Organic Compounds contaminated the groundwater posing a risk to nearby private water supply wells. The traditional approach of drilling and sampling multiple boreholes did not provide adequate data to characterize groundwater flow and contaminant migration in the complex fractured bedrock. Solution Westbay System* was installed ...


  • The variation of stygofauna along a gradient of salinization in a coastal aquifer

    We examined the variation of stygofauna composition collected in wells, along a gradient in groundwater salinity/conductivity in a coastal aquifer from southern Portugal. The studied coastal aquifer is considered vulnerable to salinization due to seawater intrusion, caused by overexploitation of the aquifer. Knowing the response of the stygofauna species to present levels of groundwater ...
