As contamination of ground water is being reported from a large areas of the Middle Ganga Plain, covering the states of Bihar and eastern Uttar Pradesh. The contamination has impacted the aquifers within the top 50-60 m in general, while the deeper aquifers, separated by low-permeable aquitards, in a multi-tiered aquifer system, are found to be free from contamination. The deeper low-Arsenic aquifers are marked with good transmissivity and can be used for community water supply through properly designed and constructed deep tube wells. The discharge and duration of pumping from such wells must be regulated to prevent any possible vertical leakage of contaminated water through the aquitards, separating the contaminated shallow aquifers and low-Arsenic deeper aquifers.

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.

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.

Water is essential for sustenance of life on earth. But the problem is unequal distribution of water in space and time. Ancients developed innovative ways to manage water resources to meet their essential needs like drinking water supplies and irrigation. Many parts of India, especially Rajasthan have been practicing water conservation and rainwater harvesting since historical times. Arwari water shed in Alwar district of Rajasthan has brought to focus traditional techniques of integrated water management with community participation. This paper attempts to briefly present the water management scenario in India since Vedic times.

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.

Gujarat State is located in the western part of India, it is well known for entrepreneurship of its peoples. Water resources in the state are very much unevenly distributed. There are very high rainfall areas in the southern part of state, whereas the northern and western parts face desert like climate. Hydrogeologically there are diverse aquifer systems. Some form prolific aquifer system like alluvial formations of North and Central Gujarat plains. There are also hard rock formations like Granites, Deccan Basalts which form poor aquifers. Due to frequent and persistent droughts water resources management has been a challenge in northern and western parts of the state. Total annual availability of water in the state is estimated at 51 BCM/ out of which surface water contribution is 38 BCM, whereas groundwater accounts for 13.58 BCM. The groundwater plays a very important role in agriculture as well as water supply in this drought prone state. The total annual Groundwater Recharge has been assessed as 22.37bcm and Annual Extractable Ground Water Resources as 21.25bcm. The Annual Ground Water extraction has been assessed as 13.58bcm and Stage of Ground Water extraction as 64%. There are 248 assessment units (talukas) out of which 25 Talukas have been categorized as ?Over- exploited?, 5 are ?Critical?, 11 are ?Semi-Critical?,194 as ?Safe? and 13 saline talukas in the state. A well-planned strategy is required for management of water resources in the state. Number of water conservation and augmentation measures have been taken up in the state in the form of Sujalam Suflam Yojna, Sauni Yojna, Participatory irrigation management, ATAL-JAL, Hydrology Project, Interlinking of Rivers to name a few. Further steps suggested for conservation and sustainable use of ground water can be augmentation of groundwater resources through Artificial Recharge, revival of ponds, reuse and recycling of wastewater, protection of water sources from pollution, conjunctive use of surface and ground water, etc

Gujarat Alluvial plains are well known for prolific aquifer system but due to overexploitation of groundwater in North Gujarat districts, the ground water levels have shown a declining trend, which entails higher water lifting cost in addition to the increasing investment in deepening of wells. As natural recharge of groundwater is not commensurate with groundwater extraction, the groundwater levels have dipped more than 190 m below ground level at some places of North Gujarat. In such areas, it is felt that artificial recharge of groundwater has much scope in water conservation and augmentation. Central Ground Water Board (CGWB) has given a new dimension to the groundwater sustainability in North Gujarat through harvesting of the surplus runoff and storing the same in the sub-surface reservoir adopting artificial recharge techniques.The present paper deals with the various activities undertaken by the Central and State Governments to arrest the groundwater level from further decline and also maintain the quality of groundwater. Based on the Pilot studies in the UNDP assisted project during the years 1980-85 in the Gujarat State, CGWB has advocated for artificial recharge of groundwater by spreading channel and injection methods to counteract the impact of overexploitation in the North Gujarat. In the Central Sector Scheme (CSS) of Ministry of Water Resources (now Ministry of Jal Shakti, Department of Water Resources, River Development & Ganga Rejuvenation), Government of India, demonstrative artificial recharge structures have been constructed by the State Government in the Saraswati river bed at Madhu Pavdi check Dam in Sidhpur, Patan district, Due to non availability of surplus water in the North Gujarat Region, Government of Gujarat launched an ambitious inter basin water transfer program known as Sujalam Sufalam Yojana. In this Sujlam Suphalam Yojana one major unlined recharge canal named as Sujlam Suphalam spreding canal has been constructed with a length of 332 km from Mahi to Banas River which diverts of surplus flood waters of Kadana Reservoir and the Narmada to the water deficit areas. In the Lift Irrigation scheme, nine reservoirs of North Gujarat region are planned to be filled by laying pipelines utilising surplus flood water of Narmada.
Ground Water Conservation and Artificial Recharge in Madhya Pradesh: A Pragmatic Approach

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.

Surface water resources in Rajasthan are scarce and scanty owing to hot arid climatic conditions. Major parts of western Rajasthan are devoid of any major drainage system and are reeled under spells of chronic droughts. Average annual rainfall in the state is of the tune of 540mm, decreases westward and is even less than 150mm in the western most parts of Jaisalmer district. Annual Potential evapo-transpiration is also as high as 2060mm in parts of Jaisalmer district. There are 15 river basins in the state. There are also numerous natural as well as artificial freshwater lakes including Pushkar, Rajsamand, Nakki, Ana Sagar, Kayalana, Ramgarh, Foy Sagar etc. mainly in the southern and eastern parts of the state. Salt lakes include Sambhar, Kuchaman, Pachpadra, Didwana, Phalodi, Lunkaransar etc. Indira Gandhi Nahar (IGNP), Bhakara and Gang canals have been constructed to bring Himalayan water to the desert areas of western Rajasthan in addition to other major commands of Chambal, Mahi and Narmada canals etc. In Rajasthan, irrigation projects completed include 22 Major projects, 77 Medium projects, 660 Minor projects and 3139 Tanks have been transferred to Panchyat Raj Department. Usable water is of the magnitude of 16.05 BCM and the Gross Storage Capacity created is of the order of 14.547 BCM. The Live Storage Capacity created is about 11.99 BCM. Out of the total allocated share of 17.88 BCM under interstate water agreement, average annual water availability remains 12.66 BCM due to various climatic, political, institutional or hydrological reasons. In addition to various Central Government Schemes, Watershed schemes and Mukhyamantri Jal Swavlamban Abhiyan are also implemented in the state.

In western India, the states Goa, Gujarat, Maharashtra and Rajasthan having area of 0.11%, 5.97%, 9.36% and 10.41% of India respectively have 0.24%, 6.83%, 13.48% and 4.52% of the total population of the country. The area, except Goa which records high precipitation, receives moderate rainfall. Arid conditions prevail in north Gujarat and major part of Rajasthan. The utilization pattern of ground water is uneven across the region resulting in ground water stressed conditions and over exploitation in some parts, particularly the arid regions and sub-optimal ground water utilization in others. Water level varies widely being very shallow in the southern part and deep to alarmingly deep in the northern part, having deepest water level of the country in Bikaner district of Rajasthan. Water quality is of concern in the major parts. In considerable areas, some chemical constituents exceed the permissible limit for drinking water, and large patches with brackish to saline water are encountered in Rajasthan and Gujarat. Sporadic occurrences of Fluoride and Nitrate in ground water exceeding the permissible limit for drinking water are spread almost throughout the region which necessitates cautious use of ground water in these areas for drinking purposes. The stage of ground water development is 37%, 68% and 54% in Goa, Gujarat and Maharashtra respectively. In Rajasthan, the stage of ground water development is 140% and 164 out of 248 ground water assessment units are overexploited and 23 ground water assessment units in Gujarat are over exploited. This requires immediate judicious intervention without which some areas will not be able to meet even the drinking water needs. Groundwater withdrawal requires to be strictly regulated so that it does not exceed the annual recharge and also that it does not disturb the hydro-chemical balance. Alarming declines in groundwater levels warrant immediate attention for taking-up of recharge schemes to arrest further decline and augment the groundwater resources. In areas of scanty recharge, ground water should be allowed only for drinking water purposes. In other areas, along with water conservation and ground water augmentation measures, demand side management using micro irrigation techniques and change of cropping pattern etc should be religiously adopted.
