  • A New Way to Locate Seeps Into Surface Waters

    How can we determine where groundwater is seeping into rivers and bays?  Knowing seep locations can help with selecting sampling locations, identifying contaminant sources, determining whether contamination is historic or on-going, and designing remediation.  Historically, methods for locating seeps have been limited.  Due to cost, sampling can only be done at a few ...

  • Surface Water / Algae Blooms Case Study

    Challenge The city river in Berlin is contaminated to the point that fish death events are common. Combined sewage overflows, stormwater runoff and the high traffic of ships are the main sources of contamination. The high amount of nutrients and the high tempratures in the summer make the river prone to algae blooms. For these reasons, the shore of the river was selected as the first ...

  • Demographic projections of future pharmaceutical consumption in the Netherlands

    Over the next few decades, many Western European countries will undergo a large demographic transformation introduced by the retirement of the "baby boomers" and the possibility of striking increases in longevity. The aim of this study was to estimate the effect of a growing and ageing Dutch population on the future consumption of pharmaceuticals, so as to be able to anticipate the potential ...

  • 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 ...

  • Spatial–temporal distribution of phthalate esters from riverine outlets of Pearl River Delta in China

    The aquatic environments of the Pearl River Delta (PRD) in China have been contaminated by various industrial chemicals from local industries. In this study, the spatial–temporal distribution of six priority phthalate esters (PAEs) in surface water and sediments from the PRD was investigated. The PAEs were detected with total concentrations (Σ6PAEs) ranging from 0.35 to 20.70 ...

  • A review on interaction of groundwater and surface water

    Interactions between groundwater and surface water play a fundamental role in water resources management. The movement of water between groundwater and surface water should be investigated in view of both quantity and quality aspects of water resources. In this paper, an attempt is made to define the primary concepts of this interaction and to illustrate a case study undertaken in ...

  • A country case study comparison on groundwater and surface water interaction

    Traditionally, managing water resources has focused on surface water or groundwater as if they were separate entities. As development of land and water resources increases, it is apparent that development of either these resources affects the quantity and quality of the other. Nearly all surface water features interact with groundwater. These interactions take many forms. This paper provides an ...

  • Quantitative estimation of groundwater recharge ratio along the riparian of the Yellow River

    Quantitative estimation of groundwater recharge is crucial for limited water resources management. A combination of isotopic and chemical indicators has been used to evaluate the relationship between surface water, groundwater, and rainfall around the riparian of the Yellow River in the North China Plain (NCP). The ion molar ratio of sodium to chloride in surface- and groundwater is 0.6 and 0.9, ...

  • Surface Water Treatment Plant, City of Clovis, CA

    Located in the northeast quadrant of the Fresno- Clovis Metropolitan Area, Clovis is situated in the midst of the agriculturally rich San Joaquin Valley. Dedicated to promoting planned growth while retaining its unique western atmosphere, the City's population has more than doubled since 1975, reaching the current level of approximately 90,000, and encompassing over 19.9 square miles in area. The ...

  • Experimental study on improvement effect of guide wall to water flow in bend of spillway chute

    In order to improve water flow in a bend of a spillway chute using a guide wall, modeling experiments with or without a guide wall under conditions of three different bend axial radii, three chute bottom slopes and three flow rates were carried out in this study. Two indexes were calculated, which are the improved water surface uniformity and the reduced rate of water surface difference in ...

  • Photochemical fate of the vasodilator drug pentoxifylline in surface waters

    This study is the first to comprehensively investigate the photochemical fate of pentoxifylline in natural water systems. Among all attenuation processes, indirect sunlight photolysis is very likely the primary process for pentoxifylline degradation. The combination of dissolved organic matter (represented by fulvic acid), NO3− and ...

  • Assessment of heavy metal pollution in surface water

    A total of 96 surface water samples collected from river Ganga in West Bengal during 2004-05 was analyzed for pH, EC, Fe, Mn, Zn, Cu, Cd, Cr, Pb and Ni. The pH was found in the alkaline range (7.21-8.32), while conductance was obtained in the range of 0.225-0.615 mmhos/cm. Fe, Mn, Zn, Ni, Cr and Pb were detected in more than 92% of the samples in the range of 0.025-5.49, 0.025-2.72, 0.012-0.370, ...

  • Surface water isolates of hemolytic and non-hemolytic Acinetobacter with multiple drug and heavy metal resistance ability

    Acinetobacter in surface waters are a major concern because of their rapid development of resistance to a wide range of antimicrobials and their ability to persist in these waters for a very long time. Four surface water isolates of Acinetobacter having both multidrug- and multimetal-resistant ability were isolated and identified through biochemical tests and 16S rDNA ...

  • Groundwater use and policy in community water supply in Finland

    Selection between ground and surface water in community water supply has been one of the key strategic questions in Finland since the early 1900s. After some cities failed to find reliable groundwater sources, many turned to surface waters. Since the 1950s the use of groundwater and artificial recharged groundwater have continuously increased. Presently their use is promoted by the government and ...

  • The natural degradation of benzophenone at low concentration in aquatic environments

    The natural degradation caused by sun irradiation and microbes in aquatic environments is of major significance in the elimination process of benzophenone (BP). In this study, the fate of BP in surface water at a low concentration of 10 μg/L was investigated, including both photodegradation and microbial degradation. The result showed that the photodegradation rate of BP was affected by ...

  • Keoladeo National Park: highlighting surface water tensions

    Keoladeo National Park in Rajasthan, India is a world-class bird sanctuary and world heritage site experiencing serious ecological stress due to drought and upstream dam construction. In response to this reoccurring scarcity of water, Indian authorities have announced a new 17 km pipeline to divert water to the wetland. Both the dam-induced water shortage and proposed pipeline solution raise the ...

Marshall Loxahatchee National Wildlife Refuge (Refuge), a remnant of the historic Everglades, in pumped stormwater discharges with a mean concentration of ...

  • Coupling FEFLOW and MIKE11 to optimise the flooding system of the Lower Havel polders in Germany

    Based on the software MIKE 11 and FEFLOW, a coupling surface water-groundwater interface has been developed to investigate the interaction for river branches, polders and wetlands. Its functionality covers the exchange of boundary conditions during runtime and the synchronisation of the temporal discretisation. The system has been applied to simple benchmark cases and complex field conditions. ...
