Chemical quality of surface and groundwater of an area is influenced by the climate, hydrological conditions, soil characteristics and geological formation. Irrespective of their source, all natural waters contain some chemical constituents and their quality changes progressively as they traverse over the land surface or infiltrate downward due to various hydro-geochemical processes. Anthropogenic factors also contribute substantially towards quality change of both surface water and ground water. In the present study an attempt has been made to understand the aquifer vulnerability to pollution, at the regional scale (Goa State), which takes into account the intrinsic hydraulic and hydrogeological parameters and environmental impacts. It is noticed that a variety of activities, such as agricultural, industrial and urban land uses, are carried out in the area, thus exposing the aquifers to a wide range of contaminants. Groundwater quality data of Goa state for the pre-monsoon seasons of 2014 and 2018 were obtained from CGWB (Bengaluru) and analysed statistically. A regional scale approach was developed which is known as ABHESHT (Aquifer type, Boundary conditions, Hydraulic Head representing static water level, Environmental impact, Solute concentration, Head variation (Water Table Fluctuation) during pre-monsoon and post-monsoon seasons and Transmissivity). The method has been applied to Goa State, west coast of India and compared with the observed groundwater quality parameters. It is found that the model has successfully delineated the wells which are prone to pollution. Using GALDIT model, seawater intrusion impact was also assessed. The study revealed that the groundwater of Goa State did not show any significant pollution indicator, however, seasonal variations in water quality parameters were observed. It is also found that the North Goa coast as well as the other tourist spots spread over the entire state show signs of pollution at various locations (Anjuna. Baga, Mapusa. Concona etc). This calls for immediate attention from the concerned authorities.

The increasing pace of ground water extraction in agricultural, industrial and domestic sectors during the past four decades has led to problems of continuously declining ground water levels and deterioration of groundwater quality in many areas of Madhya Pradesh. This has threatened the sustainability of many dug wells and tube wells. Depending heavily on agriculture-based economy, the State requires assured irrigation for sustainable agricultural productivity. Groundwater is the major source of irrigation, and also the sole source of drinking water. But the development of ground water is constrained due to heterogeneity of the formations, non-uniformity in degree and nature of the weathered and fractured zones of the aquifers. It is observed that there is heavy surface run-off in many areas during the monsoon period often resulting in floods, yet these very same areas face crisis of water during the summer. This flood? drought syndrome is basically resultant of improper management of available water resources. As ground water is an annually replenishable but limited resource, augmentation of the recharge to ground water is the only option left for ensuring its sustainability.The present study is aimed at identifying the areas in Madhya Pradesh suitable for artificial recharge to arrest the depletion of ground water resources on the one hand and create additional resources to cater to the domestic, agricultural and industrial needs in the State.

The Chhattisgarh state covers a total geographical area of about 135192 Sq. Km with subtropical climate, characterized by extreme summer and moderate winter having average rainfall of about 1300 mm. Physiographically, the area is characterized by three distinct landforms namely Bastar plateau in the South, the plain of Mahanadi river and its tributaries in the central part and the hills of Chhotanagpur plateau in the northern region. The major river basins in the state are Brahmani, Godavari, Ganga, Mahanadi and Narmada . The total catchment of these river basins is about 13559 kilometers. The Mahanadi Basin is the largest basin covering an area of about 76150 square kilometers out of 141589 square kilometers, nearly 4.3 percent of total geographical area of the country. Chhattisgarh has 2 percent population and 3.2 percent of total surface water resources of the country. The utilizable surface potential in the state if properly harnessed can irrigate about 4.3 million hectares area against the existing potential of 1.38 million hectare. Due to various anthropogenic activities, urbanization, industrialization etc, the quality and quantity of water have been adversely affected. The rivers Hasdeo, Indravati, Kharun, Apra etc. are polluted due to industrialization and urbanization in various parts of the Chhattisgarh. To check the pollution, proper management of solid/liquid waste of various industries is needed. Beside these, use of biofertilizers instead of chemical fertilizers, pesticides etc should be promoted. Effective water management strategies combined with watershed treatments like soil conservation, afforestation, desilting of rivers, rainwater harvesting etc are needed to maintain the health of the river basins of Chhattisgarh. The Jal Shakti Abhiyan started by the Government of India is a highly welcome move in this direction.

The water sector in Maharashtra is facing critical challenges. First, uneven availability of water over space and time is the biggest challenge and secondly, dramatically increasing competing demands for water from different sectors are giving rise todisputes and conflicts. Of the total water used in the state, about 82% goes to irrigation, 12% for domestic water supplies, 4% forindustrial use, and the remaining for other uses such as livestock, hydro and thermal power generation. With the urban population of about 51 million (45%), and rapidly growing urban centres and industries, there is considerable gap in demand and supply of thestate's scarce water resources. This has posed serious challenges to water security. There can be only limited dependence upon the groundwater resources for the protective irrigation in the State as 85% area is Deccan basalt having limited ground water recharge potential. Also access to safe drinking and other domestics is a challenge in the rural areas of the State. Planning and Management of water resources in a coordinated and holistic manner is needed. Considering the scarcity of water in large part of Maharashtra and substantial utilisation by irrigation sector, there is a need to expedite measures for improving Water Use Efficiency (WUE) so that water saved in irrigation can be utilised for other non-irrigation purposes. The paper gives an overview of the water resources scenario in Maharashtra with reference to surface water and discusses various water management issues that need focused attention. The paper brings out the impact of decision of various water dispute tribunals on the water availability for the State and also the need for inter-basin and intra-basin water transfer. It emphasises the need for upscaling use of Micro Irrigation (MI), Pipe distribution system, large scale integrated MI systems throughout the State etc. for not only to save substantial amount of water but also to help in increase the productivity and quality of agriculture produce. The paper also touches upon the issues of water quality and flood management in the State.

Rajasthan is the largest state of India covering an area of 3,42,239 sq.km and represents 10.5% of the country?s geographical area. On the other hand it has only 1.15% of total surface water and 2.6% of dynamic groundwater resources of the country?s resources due to arid climatic conditions. Surface water availability is restricted to command areas of canal system; hence groundwater is the only dependable source in major part of the state. Groundwater quality deterioration with depth coupled with low and erratic rainfall has generated constraints as regards availability and development potential of groundwater resources. Over exploitation of groundwater has caused mining of groundwater, which has set in declining trend in water level and threatening depletion of limited available fresh groundwater resources at an alarming rate. Management of groundwater resources in this context is an extremely complex proposition. The highly uneven distribution of groundwater and its utilization make it impossible to have single management strategy for Rajasthan as a whole. Any strategy for scientific management of groundwater resources should involve a combination of supply side and demand side measures depending on the regional setting and local geology and also on use of saline water. There are saline water tracts in various parts of the state. Recently conservation of water through crop diversification and use of saline water in several parts of the state has gained momentum.

Among the challenges faced by the world today in the area of health care, water is the greatest challenge, and this is particularly true for the developing countries. A large proportion of the world?s population relies on ground water as primary source for drinking and domestic use. In recent years, due to increase of population, urbanization, industrialization, use of chemical fertilizers, pesticide in agriculture, there is over increasing threat to surface and ground water quality. The indiscriminate use of ground water for irrigation and other purposes has resulted in sharp decline in ground water table and in changes in the natural geochemistry of ground water. In the largest areal state of the country i.e. Rajasthan higher concentration of all the three hydrochemical parameters viz. salinity, nitrate and fluoride in ground waters have adversely affected the lives of people in general and their socio-economic status in particular. Ground water of western, north-eastern parts of Rajasthan are facing problem of salinity, nitrate and fluoride, whereas central and southern parts are generally facing an acute problem of fluoride. Therefore, immediate action for mitigating the problems at government, semi-government or social levels are required for the welfare of countrymen.

Maharashtra is one of the largest states of the country and playing a vital role in the India?s economy through its agricultural and industrial growth. Agriculture is the most predominant occupation in the state and is dependent mainly on ground water irrigation. However, specific focus is being given for the demand side intervention rather than supply side interventions for management of limited ground water resources that available in the state, as the 92% of the state is underlain by hard rocks bearing limited yield potential. The rainfall is the sole source of natural recharge to aquifers and the rainy season extends for three months with barely 55 to 60 rainy days. This is the period during which aquifers get replenished and during the remaining part of this water is utilized for agriculture, domestic and industrial uses. Highest rainfall is received in the coastal areas which have very high runoff rate, whereas remaining part of the state receives rainfall varying from <400mm to 1500 mm per year. A concept plan to recharge the aquifers has been prepared, and details of the artificial recharge structures suitable for the varying geological and topographical setups have been suggested. Besides, micro irrigation techniques are also suggested for water intensive crops to regulate the ground water draft.
