Abstract:
As part of the Saph Pani project, a rapid assessment of a riverbank filtration site in Haridwar and data from literature on riverbank filtration and managed aquifer recharge in India are used for a strengths–weaknesses–opportunities–threats (SWOT) analysis based on environmental, social, institutional and economic aspects. Both technologies show a high potential for future application in India, where alternative solutions are required to mitigate water scarcity and reduce the over-exploitation of groundwater aquifers.

Abstract:
Among the several options of managed aquifer recharge (MAR) techniques, the aquifer storage and recovery (ASR) is a well-known sub-surface technique to replenish depleted aquifers, which is contingent upon the selection of appropriate sites. This paper explores the potential of ASR for groundwater recharge in the hydrological, hydrogeological, social, and economic context of South Bihar in India. Based on the water samples from more than 137 wells and socio-economic surveys, ASR installations were piloted through seven selected entrepreneurial farmers in two villages of South Bihar. The feasibility of ASR in both hard rock and deep alluvial aquifers was demonstrated for the prominent aquifer types in the marginal alluvial plains of South Bihar and elsewhere. It was postulated through this pilot study that a successful spread of ASR in South Bihar can augment usable water resources for agriculture during the winter cropping season. More importantly, ASR can adapt to local circumstances and challenges under changing climatic conditions. The flexible and participatory approach in this pilot study also allowed the farmers to creatively engage with the design and governance aspects of the recharge pit. The entrepreneurial farmers-led model builds local accountability, creates avenues for private investments, and opens up the space for continued innovation in technology and management, while also committing to resource distributive justice and environmental sustainability.

Abstract:
Soil refers to the upper layer of the Earth’s surface, which is made up of a mixture of organic residues, clay, and rock particles, and that's where plants grow. The soil quality is the environmental aspect that is most significant in agricultural activities, as well as for the concern of the safety of agricultural produces. At present-day, soil quality assessment becomes the most important issue because of the raising food security awareness. This study was assessed in Koch Bihar district, West Bengal, India, to quantify soil quality using the weighted Soil Quality Index (SQI) approach. For this assessment, the soil-related data were collected from the Soil Health Card (SHC) of the Agricultural Development Offices in all blocks of Koch Bihar and then analyzed using the principal component analysis (PCA) and expert opinion (EO) method. The weights of the selected soil quality indicators were determined using the integrated Fuzzy-AHP model. According to this method, 12 indicators, i.e., soil pH, soil electrical conductivity (EC), soil organic carbon content, nitrogen content, potassium content, phosphors content, soil texture, the groundwater level in the winter season, cropping intensity, and drainage frequency were considered based on literature review. The SQI assessment was done accordingly for each spatial unit (Block), and the spatial variability of the soil quality map was produced by GIS spatial analysis module. The findings may aid in promoting non-harmful produce production, the provision of scientific data for agricultural structure adjustment, and the maintenance of agricultural sustainability.

Abstract:
Abstract. The Indus basin is one of the regions in the world that is faced with major challenges for its water sector, due to population growth, rapid urbanisation and industrialisation, environmental degradation, unregulated utilization of the resources, inefficient water use and poverty, all aggravated by climate change. The Indus Basin is shared by 4 countries – Pakistan, India, Afghanistan and China. With a current population of 237 million people which is projected to increase to 319 million in 2025 and 383 million in 2050, already today water resources are abstracted almost entirely (more than 95% for irrigation). Climate change will result in increased water availability in the short term. However in the long term water availability will decrease. Some current aspects in the basin need to be re-evaluated. During the past decades water abstractions – and especially groundwater extractions – have augmented continuously to support a rice-wheat system where rice is grown during the kharif (wet, summer) season (as well as sugar cane, cotton, maize and other crops) and wheat during the rabi (dry, winter) season. However, the sustainability of this system in its current form is questionable. Additional water for domestic and industrial purposes is required for the future and should be made available by a reduction in irrigation requirements. This paper gives a comprehensive listing and description of available options for current and future sustainable water resources management (WRM) within the basin. Sustainable WRM practices include both water supply management and water demand management options. Water supply management options include: (1) reservoir management as the basin is characterised by a strong seasonal behaviour in water availability (monsoon and meltwater) and water demands; (2) water quality conservation and investment in wastewater infrastructure; (3) the use of alternative water resources like the recycling of wastewater and desalination; (4) land use planning and soil conservation as well as flood management, with a focus on the reduction of erosion and resulting sedimentation as well as the restoration of ecosystem services like wetlands and natural floodplains. Water demand management options include: (1) the management of conjunctive use of surface and groundwater; as well as (2) the rehabilitation and modernization of existing infrastructure. Other demand management options are: (3) the increase of water productivity for agriculture; (4) crop planning and diversification including the critical assessment of agricultural export, especially (basmati) rice; (5) economic instruments and (6) changing food demand patterns and limiting post-harvest losses.

Abstract:
Groundwater depletion is one of the most critical concerns for users and policymakers. Identifying groundwater potential (low to high) helps properly plan the available groundwater resource. This study has used the possibilities of a geographical information system (GIS), remote sensing and, of course, field data to delineate the groundwater potential zones in the Chennai River Basin (CRB). Thematic layers generated for eleven controlling factors, such as geology, water level, drainage, soil, lineament, rainfall, land use, slope, aspect, geomorphology, and depth to bedrock, were brought into the GIS environment. Then, appropriate weightage was given to each layer using a multi-criteria decision-making technique, namely, the analytic hierarchical process (AHP). A groundwater potential map is generated using weighted overlay analysis, with the following five classes: very poor, poor, moderate, good, and very good. The results were comparable to the actual specific yield data from the field and accuracy was 78.43%. Thus, AHP-aided GIS–RS mapping is a useful tool in groundwater prospecting in this region of the world.

Abstract:
Development of groundwater irrigation (GWI) has been very impressive in India, especially after the introduction of the green revolution. The area under GWI accounts for 62% of the net irrigated area today. Though GWI provides added benefits to farmers, compared to other sources of irrigation, the continuous exploitation of groundwater of late has resulted in a drastic drop in the water table, and led to salinization and quality deterioration in different parts of the country. Since groundwater contributes overwhelmingly to agricultural growth, the unrestrained exploitation of groundwater could hamper the future growth of agriculture. GWI is controlled by many factors, which are dynamic and bound to change along with the agricultural development. Therefore, one needs to understand the factors determining groundwater development in different regions over time to understand the dynamics of groundwater use. Though many studies are available on different aspects of GWI in India, not many studies have looked at the sustainable aspects of GWI, considering the major States of India together. An attempt is made in this paper to study the development as well as the factors determining GWI over time, using state-wide data to suggest appropriate interventions to sustain the use of groundwater.

Abstract:
Nitrate pollution of groundwater due to urban waste and industrial effluents usually centres around cities. This study has shown that nitrate levels in groundwater over vast agricultural areas can be correlated with intensive irrigated agriculture, corresponding use of nitrogenous fertilizers and groundwater development, and consequent diffuse agricultural pollution has already endangered the safety of potable groundwater for future generations in both rural and urban areas. Chemical and bacterial treatment of groundwater for nitrate removal relies on advanced technology and is considered costly even in the developed world. In a country like India where economic resources are inadequate, action on the suggested preventive measures may be taken without delay at this stage when alarming trends have been recorded.

Full text
Abstract:
Increasing dependence on groundwater in the Wakal River basin, India, jeopardizes water supply sustainability. A numerical groundwater model was developed to better understand the aquifer system and to evaluate its potential in terms of quantity and replenishment. Potential artificial recharge areas were delineated using landscape and hydrogeologic parameters, Geographic Information System (GIS), and remote sensing. Groundwater models are powerful tools for recharge estimation when transmissivity is known. Proper recharge must be applied to reproduce field-measured heads. The model showed that groundwater levels could decline significantly if there are two drought years in every four years that result in reduced recharge, and groundwater withdrawal is increased by 15%. The effect of such drought is currently uncertain however, because runoff from the basin is unknown. Remote sensing and GIS revealed areas with slopes less than 5%, forest cover, and Normalized Difference Vegetative Index greater than 0.5 that are suitable recharge sites.

Full text
Abstract:
Groundwater quantity allocation and quality protection in Canada largely proceed in a fragmented fashion. Each jurisdiction pursues the management of its water resources and the aquatic environment separately as well as independently of other jurisdictions. This approach is at odds with the unity of the natural environment and the inter-connectedness of groundwater resources.
The challenge facing Canada is to make the law recognize and be more responsive to the unity of the aquatic environment and water resources. An active federal role in uniting and coordinating the efforts of the provinces in this regard is crucial if this challenge is to be met. However, since the constitutional division of powers in Canada encourages a fragmented approach to managing environment and water resources, the federal government is incapacitated, purely on a legal score, with respect to pulling together the efforts of the provinces. A cooperative approach, based on political rather than legal coordination, is therefore, the most realistic option for the federal government to meet the challenge.
In this work, the writer examines the various areas for federal-provincial cooperation regarding groundwater allocation and protection. Such institutional integration or cooperation cannot be effective unless groundwater is addressed together with the other component of the hydrologic cycle, namely: surface water and the ecosystem they support. At the same time, in adopting an integrated hydrologic cycle approach, specific groundwater management strategies canvassed in this work must be taken into account if groundwater is to be more efficiently allocated and protected. Pursuant to these considerations, this writer is of the opinion that groundwater resources in Canada should be managed in a way that meets both present and future needs of Canadians, thus in a sustainable fashion. This can best be achieved if resource management relies upon a combination of contaminant-focused and resource-focused approaches adopted under unified federal-provincial efforts as well as under an integrated hydrologic cycle management.

More than 75 million people in the Bengal Delta of eastern India and Bangladesh are exposed to drinking water with dangerously high arsenic (As) concentrations; the worst case of environmental poisoning in human history. Despite recognition of dangers posed to chronic exposure to drinking water with elevated As, its biogeochemical cycle is inadequately constrained in groundwater flow systems due to its complex redox chemistry and microbially-mediated transformations. Arsenic concentrations in Bengal Delta sediments are comparable to global averages, but its highly heterogeneous spatial distribution (on scales of meters to kilometers) in sediments and groundwaters is poorly understood. Though many research efforts have targeted understanding this heterogeneity in Bangladesh, less work has been done in eastern India. Murshidabad (23°56.355‘N, 88°16.156‘E), an eastern district in West Bengal, India, where groundwaters are highly As-affected (~4000 μg/l), was chosen as our study area. Research objectives were: (1) characterize sediment cores (mineralogically, geochemically) and groundwaters (hydrochemically, isotopically) in areas with contrasting As concentrations—west (low-As) and east (high-As) of river Bhagirathi, a major distributary of Ganges flowing through the heart of Murshidabad; (2) describe and understand the extent of spatial variability, laterally and vertically, of dissolved As concentrations in shallow (< 60 m) aquifers, comparing sediment core chemistry to water chemistry; (3) identify source(s) of aquifer recharge and (4) role(s) of inorganic carbon within the aquifer to understand the bioavailability and mobilization of As from sediments to groundwaters. Mineralogical differences between high-As (grey) and low-As (orange-brown) sediments, were the presence of greater amounts of micas, Fe- and Mg-rich clays, amphiboles, carbonates, and apatite in high-As sediments; these were virtually absent from low-As sediments. In high-As areas, As was associated with amorphous and poorly-crystalline Fe-oxyhydroxide phases and labile (specifically-sorbed) phases, especially where Fe(II):Fe[subscript]T was high in the sediments. High-As groundwaters had high As(III):As[subscript]T, iron, bicarbonate, phosphate, and ammonium, and low concentrations of chloride and sulfate. Dry season precipitation was probably the main source of aquifer recharge; lighter values of [superscript]13C in dissolved inorganic carbon resulted from oxidation of natural organic matter. This study points to an idea that both microbially-mediated oxidation-reduction and competitive ion-exchange processes occurring in shallow aquifers of Murshidabad drive As mobilization and sequestration by aquifer sediments.

Abstract:
This study aimed to (1) review the reported levels of fluoride in drinking waters, food stuffs and other environmental media around the world, and the current magnitude of prevalence of fluorosis observed in human being and animals, with special reference to India and (2) critically evaluate the strategy adopted for prevention and control of the fluorosis problem in India by conducting questionnaire surveys with professionals from 11 endemic districts, and high school students of two schools located at an endemic area with high fluorosis incidences. Through a comprehensive literature review, it was able to identify 18 endemic states in India with high fluoride levels in their drinking waters while having various degrees of fluorosis problems. These states were further classified into three categories, namely high (>10 mg/L fluoride in drinking waters), moderate (5-9.9 mg/L) and low (1-4.9 mg/L) endemic regions. There were five, nine and four states falling into the high, moderate and low endemic categories, respectively. High fluoride concentrations were observed in the soil near industrial sites, foodstuffs and beverages, and tea leaves. Also, adverse effects of fluoride on terrestrial and aquatic plants, terrestrial vertebrates and invertebrates, and aquatic vertebrates and invertebrates, were observed and demonstrated in laboratory conditions. The questionnaire survey with Indian professionals in 11 fluoride endemic districts found that although all districts had received funds for combating fluorosis problems, there had been delays in executing the associated health promotion, monitoring and treatment programmes in some districts and the utilisation of the fund for the programmes was quite slow. Staff appointment, staff training, medical treatment provision, education and awareness activities, referral hospital facility provision, vehicle facility, monthly reporting, clinical survey and water and urine samples testing, timely monitoring and supervision, and involvement of various medical staff, were found to be inadequate in most districts. In the questionnaire survey conducted at the two high schools, one of the schools (school A) was supplied with alternate source of filtered water (i.e., with normal fluoride concentration) and the second school (school B) was one, which had non-defluoridated ground water supply for drinking (i.e., with high fluoride concentration). This survey found that the awareness about signs of fluorosis, field visit of health worker, cause and preventability of fluorosis, and perception of spread of fluorosis, was comparatively better amongst students of school A than that of school B. Both the schools’ students had positive attitude towards cooperation, prevention and control efforts being made for fluorosis.

Abstract:
Hundreds of millions of people worldwide are exposed to arsenic-contaminated drinking water, leading to significant health complications, and social and economic losses. Currently, a wide range of technologies exists to remove arsenic from water. However, despite ongoing research on such technologies, their widespread application remains limited. To bridge this gap, this review aims to compare the effectiveness and costs of various arsenic remediation technologies while considering their practical applicability. A search conducted using the Medline and Embase databases yielded 31 relevant articles published from 1996 to 2018, which were categorized into laboratory and field studies. Data on the effectiveness of technologies in removing arsenic and associated costs were extracted and standardized for comparison as much as was possible, given the diversity of ways that studies report their key results. The twenty-three (23) technologies tested in laboratory settings demonstrated efficiencies ranging from 50% to ~100%, with the majority reaching relatively high removal efficiencies (>90%). Approximately half achieved the WHO standard of 10 µg/L. Laboratory studies used groundwater samples from nine (9) different countries – Argentina, Bangladesh, Cambodia, China, Guatemala, India, Thailand, the United States, and Vietnam. The fourteen (14) technologies tested in the field achieved removal efficiency levels ranging between 60% and ~99%, with ten (10) attaining above 90% removal efficiency. Of these, only five (5) reached established the WHO standard. Some of the technologies under-performed when their influent water contained excessive concentrations of arsenic. Only six (6) countries (Argentina, Bangladesh, Chile, China, India, and Nicaragua) were represented among the studies that implemented and tested technologies in the field, either at household or community level. For technologies tested in the laboratory, the cost of treating one cubic meter of water ranged from near-zero to ~USD 93, except for one technology which cost USD 299/m³. For studies conducted in the field, the cost of treating one cubic meter of water ranged from near-zero to ~USD 70. Key factors influencing the removal efficiencies and their costs include the arsenic concentration of the influent water, pH of the influent water, materials used, the energy required, absorption capacity, labour used, regeneration period and geographical location. Technologies that demonstrate high removal efficiencies when treating moderately arsenic-contaminated water may not be as efficient when treating highly contaminated water. Also, the lifetime of the removal agents is a significant factor in determining their efficiency. It is suggested that remediation technologies that demonstrate high arsenic removal efficiencies in a laboratory setting need to be further assessed for their suitability for larger-scale application, considering their high production and operational costs. Costs can be reduced by using locally available materials and natural adsorbents, which provide near zero-cost options and can have high arsenic removal efficiencies. A notable feature of many arsenic removal approaches is that some countries with resource constraints or certain environmental circumstances – like typically high arsenic concentrations in groundwater –aim to reach resultant arsenic concentrations that are much higher than WHO’s recommended standard of 10 µg/L. This report maintains that – while this may be a pragmatic approach that helps progressively mitigate the arsenic-related health risks – it is unfortunately not a sustainable solution. Continuing exposure to higher levels of arsenic ingestion remains harmful for humans. Hence arsenic-removal technology should only be seen efficient if it can bring the water to the WHO standard. A less radical approach effectively shifts the attention from the origin of the problem in addressing the impacts and postpones achieving the best possible outcome for populations. The quantitative summary of costs and effectiveness of arsenic remediation technologies reviewed in this report can serve as a preliminary guideline for selecting the most cost-effective option. It may also be used as an initial guideline (minimum standard) for summarising the results of future studies describing arsenic remediation approaches. Looking ahead, this study identifies four priority areas that may assist in commercializing wide-scale implementation of arsenic removal technologies. These include: i) focusing efforts on determining market viability of technologies, ii) overcoming practical limitations of technologies, iii) determining technology contextual appropriateness and iv) concerted effort to increase knowledge sharing in and across regions to accelerate the implementation of research on the ground. Overall, the current science and knowledge on arsenic remediation technologies may be mature enough already to help significantly reduce the global numbers of affected populations. The missing link for today’s arsenic removal challenge is the ability to translate research evidence and laboratory-level successes into quantifiable and sustainable impacts on the ground. Achieving this requires a concerted and sustained effort from policymakers, engineers, healthcare providers, donors, and community leaders.
