The Chernobyl Nuclear Power Plant (NPP) disaster that occurred in Ukraine on April 26, 1986, was one of the most devastating in human history. Using this as a case study, the AGU monograph Groundwater Vulnerability: Chernobyl Nuclear Disaster is devoted to the problem of groundwater vulnerability, where the results of long-term field and modeling investigations of radionuclide transport in soil and groundwater, within the Ukrainian part of the Dnieper River basin (Kyiv region of Ukraine), are discussed. The authors provide a comprehensive review of existing literature on the assessment of groundwater vulnerability and then describe an improved methodology, which is developed based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward groundwater. This volume also includes the evaluation of the effect of preferential and episodic flow on transport of radionuclides toward the aquifers and risk assessment of groundwater vulnerability, which can further assist future researchers in developing remediation technologies for improving drinking water quality. Further, this volume sheds light on the consequences of groundwater contamination from nuclear disasters and assists with assessing the risks associated with contamination and developing effective remediation technologies. Volume highlights include discussions of the following: – Assessment of groundwater vulnerability to contamination from the Chernobyl nuclear disaster – Novel analytical results of the 25-year investigations of groundwater contamination caused by Chernobyl-born radionuclides – The wealth of data on different modes of radioactive transport in the atmosphere, water, and soils, and along the food chains – The hydrogeological and physico-chemical processes and factors in groundwater contaminated zones – The applicability of commonly used methods of the evaluation of groundwater vulnerability – A unique method of fluid dynamics that involves an anomalously fast migration of contaminants through zones of preferential flow from the land surface toward groundwater – Building confidence in the assessment of migration pathways of radionuclides in the biosphere – Assessment and prediction of the consequences of the nuclear accident, which can shed light on protection from global nuclear accidents – Analogue information for different nuclear waste disposal and environmental projects around the world

Groundwater is the most important source of fresh water supply for drinking all over the world. Groundwater samples from different location of Jhenaidaha Municipality have been analyzed to assess the chemical composition, source rock and quality. The parameter analyzed for the research are pH, TDS, EC, Na+, K+, Ca2+, Mg2+, Cl-, HCO3-, SO42-, PO43-, H4SiO4 and NO2-N. The analysis reveals that the cations and anions of the water shows the order of dominance as Ca2+>Mg2+> Na+>K+ and HCO3->Cl->SO42- respectively. The Na+/ (Na++Ca2+) weight ratio against TDS illustrates that the water is derived mainly from rock weathering; however few samples suggest dominance of evaporation crystallization process. Deduction of source rock demonstrates that carbonate weathering and cation exchange is predominant in almost all over the study area. Piper diagram indicates that the water is rich in Ca2+ + Mg2+ and HCO3- (temporary hard) in the study area. This study reveals that the water quality of shallow aquifers in Jhenaidaha Municipality is quite satisfactory and meets the drinking water standard of Bangladesh and WHO.

Groundwater is one of the Earth’s most precious resources. We use it for drinking, bathing, and many other purposes. Without clean water, humans would cease to exist. Unfortunately, because of ignorance or lack of caring, groundwater is often contaminated through industrialization, industry, construction or any number of other ways. It is the job of the environmental engineer to remediate the contaminated groundwater and make what has been tainted safe again.Selecting the proper remediation strategy and process is the key to moving forward, and, once this process has been selected, it must be executed properly, taking into consideration the costs, the type of contaminants that are involved, time frames, and many other factors. This volume provides a broad overview of the current and most widely applied remedial strategies. Instead of discussing these strategies in a generic way, the volume is organized by focusing on major contaminants that are of prime focus to industry and municipal water suppliers. The specific technologies that are applicable to the chemical contaminants discussed in different chapters are presented, but then cross-referenced to other chemical classes or contaminants that are also candidates for the technologies. The reader will also find extensive cost guidance in this volume to assist in developing preliminary cost estimates for capital equipment and operations & maintenance costs, which should be useful in screening strategies. The eight chapters cover all of the major various types of contaminants and their industrial applications, providing a valuable context to each scenario of contamination. This is the most thorough and up-to-date volume available on this important subject, and it is a must-have for any environmental engineer or scientist working in groundwater remediation.

Hydrodynamics of Time-Periodic Groundwater Flow introduces the emerging topic of periodic fluctuations in groundwater. While classical hydrology has often focused on steady flow conditions, many systems display periodic behavior due to tidal, seasonal, annual, and human influences. Describing and quantifying subsurface hydraulic responses to these influences may be challenging to those who are unfamiliar with periodically forced groundwater systems. The goal of this volume is to present a clear and accessible mathematical introduction to the basic and advanced theory of time-periodic groundwater flow, which is essential for developing a comprehensive knowledge of groundwater hydraulics and groundwater hydrology. Volume highlights include: Overview of time-periodic forcing of groundwater systems Definition of the Boundary Value Problem for harmonic systems in space and time Examples of 1-, 2-, and 3-dimensional flow in various media Attenuation, delay, and gradients, stationary points and flow stagnation Wave propagation and energy transport Hydrodynamics of Time-Periodic Groundwater Flow presents numerous examples and exercises to reinforce the essential elements of the theoretical development, and thus is eminently well suited for self-directed study by undergraduate and graduate students. This volume will be a valuable resource for professionals in Earth and environmental sciences who develop groundwater models., including in the fields of groundwater hydrology, soil physics, hydrogeology, geoscience, geophysics, and geochemistry. Time-periodic phenomena are also encountered in fields other than groundwater flow, such as electronics, heat transport, and chemical diffusion. Thus, students and professionals in the field of chemistry, electronic engineering, and physics will also find this book useful.

Rahul Kamble Spatial Distribution of Groundwater Manganese in Central India

Academic Paper from the year 2017 in the subject Environmental Sciences, , course: PhD Environmental Science, language: English, abstract: Groundwater manganese concentration from the Chandrapur district of Central India was assessed during winter 2012. Groundwater sampling was carried out by grab sampling method in 36 sampling locations comprised of 34 hand pumps and two dug wells. Groundwater samples for manganese were preserved by adding conc. Groundwater manganese concentrations were estimated by Inductively Coupled Plasma-Optical Emission Spectroscopy. Groundwater iron concentration from the study area during winter 2012 was in the range of 0.0015-1.85 mg/L (SD±0.36). Groundwater manganese concentration in seven water samples were above the permissible desirable limit of Indian Standards for drinking water (IS 10500:2012, desirable limit for Mn, 0.3 mg/L max.). This elevated concentration of manganese in groundwater from the study area can be attributed to weathering of mineral bearing rocks, mining activities and also to some extent to anthropogenic activities. Spatial distribution of manganese was observed in the study area. Further, shallow, deep and very deep well water had variable manganese concentration. Upper earth surface had lower manganese concentration, however present, can be attributed to anthropogenic activities whereas deeper earth surface had higher manganese concentration that can be assigned to geogenic origin.

In Finland, most water is held in the soil than the surface systems. Hence, Finland's water resources depend on groundwater and biogeochemical processes. The study of groundwater in peatland is important for maintaining ecological balance and conservation of water resources. The groundwater level is one of the key indicators of aquifer conditions and groundwater basins. It helps to interpret hydrogeology, groundwater flow, groundwater sustainability and land usability. The study tries to analyze ground water recharge on peatland catchments using hydrograph recession analysis. The equation for the hydrograph recession curve can be utilized to predict groundwater recharge during each recession period. The steps involved during recession curve analysis includes selection of analytical expression, derivation of recession characteristic and optimization of the parameters. While computing groundwater recharge with recession curve, the high variability of each recession segments creates major problem. Each segment shows the outflow process which creates short-term or seasonal influence. The variation in rate of recession which causes problems for derivation of recession...

Deka Gitimoni, Bhattacharyya Krishna Gopal Impacts of a Textile Mill on Water and Soil Quality

This work investigates the impacts of the effluents and other wastes of a Textile Mill on quality of soil and water in the surrounding areas. Some specific impacts on soil and water quality have been identified. For example, the soil was getting enriched with both ionic matter and hydrophobic organic matter, which had important consequences. The soil became enriched with the trace metals, As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn. The quality of the drinking water in and around the textile mill did reflect the changes in the physico-chemical quality of the soil. The water was characterized by considerable presence of the cations, Ca, Mg, Na and K, being compensated by comparative presence of the anions, Cl, NO3 and SO4. The toxic organic contaminant, phenol, was present in some of the drinking water sources. The water was contaminated with Mn, Ni, and Pb, and also fluoride. The rice crop grown in the study area had accumulated appreciable amounts of metals in them as seen from the analysis of rice grains and husks. Significantly, the husks were seen to be richer in the metals than the grains with one or two exceptions.

Microbiology of Drinking Water Production and Distribution addresses the public health aspects of drinking water treatment and distribution. It explains the different water treatment processes, such as pretreatment, coagulation, flocculation, sedimentation, filtration, disinfection, and their impacts on waterborne microbial pathogens and parasites. Drinking water quality may be degraded in water distribution systems—microorganisms form biofilms within distribution systems that allow them to flourish. Various methodologies have been proposed to assess the bacterial growth potential in water distribution systems. Microbiology of Drinking Water Production and Distribution also places drinking water quality and public health issues in context; it addresses the effect of bioterrorism on drinking water safety, particularly safeguards that are in place to protect consumers against the microbial agents involved. In addition, the text delves into research on drinking water quality in developing countries and the low-cost treatment technologies that could save lives. The text also examines the microbiological water quality of bottled water, often misunderstood by the public at large.

Ranjin Fernando Hydromorphologic survey and assessment of the lakeshore of Lake Scharmutzelsee as a prerequisite for the development of a lakeshore utilization strategy

Lakeshores are ecotones between aquatic and terrestrial habitats with a high economic and socio-economic significance. For many years, lake conservation focused on biological and chemical conditions and while improvements on these fields have been achieved, the anthropogenic pressures on European lakeshores have rather increased in recent years. Against this background, the development of utilization and protection strategies for lakeshores is urgently needed. A precondition for this is a standardized survey and assessment of the hydromorphological status which is also required by the European Water Framework Directive under certain circumstances. For this thesis, the lakeshore of Lake Scharmützelsee, the largest lake in the German state of Brandenburg, was classified according to the GIS-based Hydromorphology Lake (HML) protocol of Ostendorp (2008). Since the HML protocol was at the time still in a testing phase, methodical modifications were applied and recommendations for an improvement of the protocol are given. Deviating from the HML protocol, the eulittoral zone was delineated with a constant width of five meters and the sublittoral zone according to the potential maximum water depth where the available light permits the growth of submerged macrophytes. A detailed on-site mapping and a separate assessment of linear and planar objects in the eulittoral zone enhanced the quality of the data further. For Lake Scharmützelsee, the assessment showed an expected increase in an...

Pardeep Singh, Anwesha Borthakur Surface and Ground Water Interaction

Water is known to be a fundamental element of all forms of life. It is commonly used as solvent, for drinking, for cleaning purposes and various other ways. Needless to say, it has to be clean water. Water pollution on the other hand, decreases the water's usefulness economically and aesthetically. When water becomes polluted, it brings danger to our health and to the other living things. The most serious effects of water pollution are infectious diseases, which commonly occur in developing countries, where there is a problem with sanitation. Water-borne diseases occurs when microscopic causal organisms spread through water body,90% of the world diseases are cause due to water contamination. Groundwater and Surface-Water Interactions: As development of land and water resources increases, it is apparent that development of either of these resources affects quantity and quality of the other. Nearly all surface- water features interacts with groundwater. These interactions take many forms. In many situations, surface water bodies gain water and solutes from ground water system and in others the surface water is a source of ground water recharge and cause changes in ground water

Metals are non-biodegradable and are considered as major environmental pollutants causing cytotoxic, mutagenic and carcinogenic effects in animals. Aquatic organisms have the ability to accumulate heavy metals from various sources including sediments, soil erosion and runoff, air depositions of dust and aerosol, and discharges of waste water. Therefore, accumulation of heavy metals in aquatic organisms can pose a long lasting effect on biogeochemical cycling in the ecosphere.The rapid growth of population in the catchment areas may lead to deterioration of lake water quality (biolgical/chemical). The present investigation was carried out to study the water quality issues in terms of metal contents of Rawal Lake Islamabad Pakistan, which is major drinking water reserviour for inhabitants of Rawalpindi/Islamabad.

Introduction to Chemical Engineering Kinetics & Reactor Design enables readers to progressively build their knowledge and skills by applying the laws of conservation of mass and energy to increasingly more difficult challenges in reactor design. The first one-third of the text emphasizes general principles of chemical reaction kinetics, setting the stage for the subsequent treatment of reactors intended to carry out homogeneous reactions, heterogeneous catalytic reactions, and biochemical transformations. Topics include: Thermodynamics of chemical reactions Determination of reaction rate expressions Elements of heterogeneous catalysis Basic concepts in reactor design and ideal reactor models Temperature and energy effects in chemical reactors Basic and applied aspects of biochemical transformations and bioreactors About 70% of the problems in this Second Edition are new. These problems, frequently based on articles culled from the research literature, help readers develop a solid understanding of the material. Many of these new problems also offer readers opportunities to use current software applications such as Mathcad and MATLAB®. By enabling readers to progressively build and apply their knowledge, the Second Edition of Introduction to Chemical Engineering Kinetics & Reactor Design remains a premier text for students in chemical engineering and a valuable resource for practicing engineers.

Petri Nets were defined for the study of discrete events systems and later extended for many purposes including dependability assessment. In our knowledge, no book deals specifically with the use of different type of PN to dependability. We propose in addition to bring a focus on the adequacy of Petri net types to the study of various problems related to dependability such as risk analysis and probabilistic assessment. In the first part, the basic models of PN and some useful extensions are briefly recalled. In the second part, the PN are used as a formal model to describe the evolution process of critical system in the frame of an ontological approach. The third part focuses on the stochastic Petri Nets (SPN) and their use in dependability assessment. Different formal models of SPN are formally presented (semantics, evolution rules…) and their equivalence with the corresponding class of Markov processes to get an analytical assessment of dependability. Simplification methods are proposed in order to reduce the size of analytical model and to make it more calculable. The introduction of some concepts specific to high level PN allows too the consideration of complex systems. Few applications in the field of the instrumentation and control (l&C) systems, safety integrated systems (SIS) emphasize the benefits of SPN for dependability assessment.

C. P. Kumar Impact of Climate Change on Groundwater Resources

Academic Paper from the year 2014 in the subject Geography / Earth Science - Meteorology, Aeronomy, Climatology, , language: English, abstract: Climate change poses uncertainties to the supply and management of water resources. The Intergovernmental Panel on Climate Change (IPCC) estimates that the global mean surface temperature has increased 0.6 ± 0.2 oC since 1861, and predicts an increase of 2 to 4 oC over the next 100 years. Temperature increases also affect the hydrologic cycle by directly increasing evaporation of available surface water and vegetation transpiration. Consequently, these changes can influence precipitation amounts, timings and intensity rates, and indirectly impact the flux and storage of water in surface and subsurface reservoirs (i.e., lakes, soil moisture, groundwater). In addition, there may be other associated impacts, such as sea water intrusion, water quality deterioration, potable water shortage, etc. While climate change affects surface water resources directly through changes in the major long-term climate variables such as air temperature, precipitation, and evapotranspiration, the relationship between the changing climate variables and groundwater is more complicated and poorly understood. The greater variability in rainfall could mean more frequent and prolonged periods of high or low groundwater levels, and saline intrusion in coastal aquifers due to sea level rise and resource reduction. Groundwater resources are related to climate change...

The Chernobyl Nuclear Power Plant (NPP) disaster that occurred in Ukraine on April 26, 1986, was one of the most devastating in human history. Using this as a case study, the AGU monograph Groundwater Vulnerability: Chernobyl Nuclear Disaster is devoted to the problem of groundwater vulnerability, where the results of long-term field and modeling investigations of radionuclide transport in soil and groundwater, within the Ukrainian part of the Dnieper River basin (Kyiv region of Ukraine), are discussed. The authors provide a comprehensive review of existing literature on the assessment of groundwater vulnerability and then describe an improved methodology, which is developed based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward groundwater. This volume also includes the evaluation of the effect of preferential and episodic flow on transport of radionuclides toward the aquifers and risk assessment of groundwater vulnerability, which can further assist future researchers in developing remediation technologies for improving drinking water quality. Further, this volume sheds light on the consequences of groundwater contamination from nuclear disasters and assists with assessing the risks associated with contamination and developing effective remediation technologies. Volume highlights include discussions of the following: – Assessment of groundwater vulnerability to contamination from the Chernobyl nuclear disaster – Novel analytical results of the 25-year investigations of groundwater contamination caused by Chernobyl-born radionuclides – The wealth of data on different modes of radioactive transport in the atmosphere, water, and soils, and along the food chains – The hydrogeological and physico-chemical processes and factors in groundwater contaminated zones – The applicability of commonly used methods of the evaluation of groundwater vulnerability – A unique method of fluid dynamics that involves an anomalously fast migration of contaminants through zones of preferential flow from the land surface toward groundwater – Building confidence in the assessment of migration pathways of radionuclides in the biosphere – Assessment and prediction of the consequences of the nuclear accident, which can shed light on protection from global nuclear accidents – Analogue information for different nuclear waste disposal and environmental projects around the world
