The industrial dumping sites located in the southern provinces of Poland pollute the groundwater with metals. In the article, the possibility of groundwater (polluted by metals) treatment with the use of PRB Technology has been presented. In this technology, the contaminants are removed from the aquifer by the flow of the groundwater through a PRB ...

Remediation of Cr(VI) requires the reduction of the mobile state [Cr(VI)], which exists in the natural environment as the oxyanionic species (CrxOyz−), to the less mobile trivalent state [Cr(III)], which readily forms the hydroxide precipitate [Cr(OH)3(s)] under natural pH conditions. In this study, Cr(VI) reduction is investigated using ...

Defining aquifer permeability distribution accurately over large areas is often debated in hydrogeology. The operational efforts to calculate hydraulic conductivity with classical aquifer tests are significant; however, accurate knowledge of permeability areal distribution is fundamental both from a hydrogeological and a modeling standpoint. ...

Throughout most of human existence, population growth has been so slow as to be imperceptible within a single generation. Reaching a global population of 1 billion in 1804 required the entire time since modern humans appeared on the scene. To add the second billion, it took until 1927, just over a century. Thirty-three years later, in 1960, world ...

Aquifer thermal energy storage (ATES) uses groundwater to store energy for heating or cooling purposes in the built environment. This paper presents field and laboratory results aiming to elucidate the effects that ATES operation may have on chemical groundwater quality. Field data from an ATES site in the south of the Netherlands show that ATES ...

Stimulating microbial growth through the use of acetate injection wells at the former uranium mill site in Rifle, Colorado, USA, has been shown to decrease dissolved uranium (VI) concentrations through bacterial reduction to immobile uranium (IV). Bioreduction also changed the redox chemistry of site groundwater, altering the mobility of ...

Sizing a Pressure Tank with a CSV Cycle Stop Valves utilize a very small pressure tank. A 4.4 gallon size pressure tank is all you need for any size house.  “The larger the pressure tank the better”, is no longer true. Water does not come from the pressure tank. Your entire supply of water is pumped from the aquifer, ...

Current research on groundwater vulnerability is aimed mainly at groundwater pollution vulnerability (GPV), and the vulnerability of groundwater quantity is seldom considered. It is important to carry out the groundwater vulnerability evaluation for the management of groundwater resources. This paper presents evaluation models and methods for ...

This report reviews some current sustainability targets for the water sector and provides an overview of selected tools and approaches to assist decision-makers improve performance and achieve results ¿ and ultimately, meet development targets. The report reviews three widely known systems of water sustainability targets: the water targets ...

This paper reports on the intentions of urban residents in two South Australian Local Government Areas (LGAs) (council areas) to use stormwater treated through a managed aquifer recharge process for various potential non-potable uses. Data were collected through an online survey of the residents in these LGAs. The key finding is that, in common ...
