  • Availability and Security of Water Services

    Water has become a crucial resource worldwide. Surface water and groundwater are the primary sources of water.  The impacts for the the availability of water were generated from work from a variety of sources (FCO 2010).  At present, approximately 1.5 billion people, out of a total world population of around 6 billion, live in major watersheds where average river runoff is less than ...

  • Global Monthly Water Scarcity: Blue Water Footprints versus Blue Water Availability

    Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by ...

  • In Situ Biological Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of in situ treatment is that it allows ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ treatment, however, generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • Rainfall and surface water resources of Rajasthan State, India

    The water resources in Rajasthan State are facing a crucial stage even after average/good rainfall. Temporal distributions as well as the spatial variability of rainfall within the state were investigated by applying an analysis of variance (ANOVA) test. The effect of change in catchment characteristics and anthropogenic activities on overland flow are also investigated in this paper by ...

  • Ex Situ Physical/chemical Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the ground water. Ex situ treatment, however, requires pumping of ground water, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

  • Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate

    Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

  • Hydraulic “Fracking”: Are surface water impacts an ecological concern?

    Use of high‐volume hydraulic fracturing (HVHF) in unconventional reservoirs to recover previously inaccessible oil and natural gas is rapidly expanding in North America and elsewhere. Although hydraulic fracturing has been practiced for decades, the advent of more technologically advanced horizontal drilling coupled with improved slickwater chemical formulations has allowed extensive natural ...

  • Cleaning mold containing surfaces

    Once a determination is made that a moldy surface can be cleaned instead of removed or demolished, what cleaning agents are effective in removing or killing the mold? Many factors influence the selection of a cleaning agent. 1). The type of surface to be cleaned: Is it porous? Hard such as cement or sheetrock? Soft, such as cloth, fabric or wallpaper? Absorbent and thick such as rugs, ...

  • Modeling NOM removal by softening in a surface water treatment plant

    Phenomenological models and hybrid phenomenological–chemometric models were developed to predict natural organic matter (NOM) removal based on the real water treatment data from the city of Minneapolis over a 3 year period. The analysis of the modeling results showed that the phenomenological model was able to capture the major variations of NOM removal but it tended to over predict the ...

  • A four-step guide to accurately calculating surface water discharge

    Today, a wide range of government agencies, municipalities, utility companies, and private companies need to monitor water flow in rivers, streams, and canals for a variety of reasons ranging from predicting water availability and flood events to allocating water resources and planning for future development. At a high-level, these organizations are concerned with the water flow and discharge of ...

  • Partitioning and availability of sediment-bound metals following final sewage effluent release to a lowland river

    A simple partitioning scheme was used to assess the partitioning and behaviour of copper, cadmium, iron, lead and manganese within the surface waters and sediments of the River Yare, Norfolk, UK, following the discharge of final effluent to the water course from municipal sewage treatment works (STW). Sewage effluent discharges were shown to increase metal concentrations and complexation ...

  • Augmentation of surface water sources from spatially distributed rainfall in Saudi Arabia

    This study investigated the rainfall patterns, spatial variability, surface runoff generation and dam requirements in the southwestern region of Saudi Arabia. The region was divided into four areas Asir, Jazan, Al-Baha and the Red Sea Coast. Surface runoff was estimated for eight scenarios considering the runoff coefficients of 0.05–0.70, resulting in 203–2,835 million cubic meters (MCM) of ...
