This paper presents the results and assessment of the groundwater exploitation reserves in coastal areas of Ninh Thuan province. The research was based on determining the exploitation reserves of all grid cells with dimensions 500 m × 500 m distributed in fresh-salted water areas of the Holocene (qh) and Pleistocene (qp) aquifers. Each grid was assigned the corrected hydrogeological parameter values (depth, gravity coefficient, hydraulic conductivity, and drawdown level).

Groundwater potential zoning using Logistics Model Trees based novel ensemble machine learning model
n this work, the main aim is to map the potential zones of groundwater in Central Highlands (Vietnam) using a novel ensemble machine learning model, namely CG-LMT, which is a combination of two advanced techniques, namely Cascade Generalization (CG) and Logistics Model Trees (LMT). For this, a total of 501 wells data and a set of twelve affecting factors were gathered and selected to generate training and testing datasets used for building and validating the model.

Synchrotron-based X-ray absorption spectroscopy (XAS), specifically X-ray absorption near edge structure (XANES) spectroscopy, indicated the dominant species of As in soil and sediment samples was arsenate [As(V)], which is similar to the chemical form of As in the groundwaters of this region. No evidence of arsenite [As(III)] was identified in any of the solid-phase samples, including earthworm castings.

The results revealed that surface water possessed more potential non-carcinogenic harmful health risks to the residents of the study area to compare to groundwater. As regards carcinogenic health risks, on average there is a possibility of 5 persons in every 106 developing cancer due to lifetime exposure to Cd through ingestion of groundwater.

Removal of pollutants from water/waste water using nano-adsorbents: A potential pollution mitigation
Nano-adsorbents have gained special attention in water pollution mitigation in India since last decade. Two vital properties make nanoparticles highly lucrative as adsorbents. On a mass basis, nano-particles have much larger surface areas compared to macro particles. They can also be enhanced with various reactor groups to increase their chemical affinity towards target compounds. Nano-adsorption techniques are now widely used to remove cations, natural organic matter, biological contaminants, inorganic pollutants, nitrates and arsenic from groundwater, surface water and industrial effluents.

In India, agriculture is important occupation of which 52.00 per cent of the people depend for their livelihood. Although agriculture dominates the primary sector however it has not reached its potential level, since most of the farmers use traditional technology, slow adoption of modern and proven technologies which impaired productivity and results in lower standard living of the framers in the region.

In this study a standard methodology is proposed to determine groundwater potential using integration of RS & GIS technique. The composite map is generated using GIS tools. The accurate information to obtain the parameters that can be considered for identifying the groundwater potential zone such as geology, slope, drainage density, geomorphic units and lineament density are generated using the satellite data and survey of India (SOI) toposheets of scale 1:50000. It is then integrated with weighted overlay in ArcGIS.

Water is one of the most essential commodities for mankind and the largest available source of fresh water lays underground. Tremendous increase in the agricultural, industrial and domestic activities in recent years has increased the demand for good quality water to meet the growing needs. Groundwater is mostly preferred to meet this growing demand because of its lower level of contamination and wider distribution. The occurrence of groundwater is a consequence of the interaction of the climatic, geological, hydrological and physiographical factors.

As the demand and needs of the population towards water is growing the value of water is felt in all sectors. At the same time, surface water resources are becoming insufficient to fulfill the water demand. So that systematic planning of groundwater improvement using modern technique is fundamental for the proper management and utilization of this precious resource.

The performances of five biodrainage species were monitored for its soil moisture depletion, groundwater table depression and soil fertility improvement in waterlogged lowland of Indo-Gangetic alluvial plains of West Bengal. The results of the study showed that all biodrainage plantations had differential potential in extracting surplus water from deeper soil layers and consequent recession of groundwater table.

Groundwater is a treasured underground resource, which plays a central role in sustainable water management. However, it being hidden and dynamic in nature, its sustainable development and management calls for precise quantification of this precious resource at an appropriate scale. Chance of getting good groundwater at shallow depths for irrigation is always considered as a blessing for the farmers.

The use of a wide range of chemicals to destroy pests and weeds is an important aspect of agricultural practice in both developed and developing countries. This has increased crop yield and reduced postharvest losses. However, the expanded use of such pesticides expectedly results in residues in foods, which has led to widespread concern over the potential adverse effects of these chemicals on human health.

This paper is about the impact of climate change on water resources, mainly focusing upon the consequences of climate change on Ladakh people based on both qualitative and quantitative approaches. Inadequacy of water resources, irregular rainfall pattern and coping up under such scared water consequences are the major problems in the study area. The main sources of water are glaciers, hand pump, stream and springs.
