Ground Water, a prime and precious resource of the nature and an important component of water cycle, has emerged as a ‘Democratic resource’ in the State of U.P. because of relative ease to exploit it with greater flexibility and, therefore, the dependency on this resource has increased manifold. Now, ground water has attained a vital position in the overall water resource development plans & programs of the State, especially in drinking water sector. The demand of this resource is growing in multiple proportions and its contribution can be assessed by the fact that ground water resource is fulfilling more than 80% of drinking water demand in the State.

Last three decades have seen an exponential growth in the number of ground water based drinking water supply schemes in rural segment. Still there are a number of habitations yet to be covered with assured drinking water source. As per the U.P. Jal Nigam’s estimates, about 12000 million liters of ground water is being extracted every day for drinking purposes both in urban & rural areas of the State. The ever-increasing drinking water requirements have also put ground water reservoirs under ‘stress’.

The continuous & escalated abstraction of ground water resource in irrigation, industrial and drinking water sectors has resulted into widespread depletion of aquifers causing decline of ground water levels to alarming stage. As per the studies of Ground Water Department, 630 blocks are affected with ground water level decline, requiring rain water harvesting measures for ground water recharge.

Besides, ground water quality is also an area of great concern for ensuring safe water supplies in the rural habitations of the State. The quality aspect of ground water resources has emerged as a new threat and, therefore, ground water pollution has now become a burning issue. Studies reveal that the inadequate sewerage system, improper waste disposal sites & various industrial activities, besides natural geogenic and anthropogenic causes are responsible for contaminating ground water. The findings of quality assessment of ground water, so far taken up in isolation by different organizations/agencies, have shown that ground water, at places, is contaminated with Fluoride, Arsenic, Iron, TDS, Nitrate along with reported presence of heavy metals  and also the pesticide residue. However, it is also noticeable that the quality reports so far available do not represent the actual quality status of ground water in the State.

To cope up with such impact of over-development, unplanned use and improper activities, the imperative need is to scientifically assess the ground water resource through a well-established system of geo-referenced monitoring network of drinking water sources for systematic study of ground water quality in the State.


The Uttar Pradesh is a part of Ganga basin comprising Yamuna, Ramganga, Gomti, Ghaghra and Sone sub basins. The State is further divided into four major hydrogeological zones namely Terai zone, Central Ganga plain, Marginal Alluvial plain and Southern peninsular zone. The Bhabhar zone includes very small areas covering parts of Bijnor and Saharanpur districts infringing the international boundary in northern most part of the State. The Central Ganga plain constitutes the major geographical area of the State.

The distribution of ground water is quite uneven and uncertain due to varied hydrogeological and hydro-geomorphological setup of the State. The depth to ground water levels generally varies from 2 meters below ground level (mbgl) to even as deep as 30 mbgl. This wide variation in ground water levels is due to different hydrogeological conditions that prevail across the State. In the canal command such as Sharda Sahayak, Upper Ganga, Gandak etc. shallow water levels of less than 2 mbgl are observed. The deeper water levels of more than 20 mbgl are observed in ravine tract along Yamuna River between district Agra and Allahabad.


A number of Organizations in the State are dealing with the water quality issues for their respective schemes/programs. However, the emerging trends of deteriorated ground water quality are quite disturbing considering the challenges of potable water supplies. Ground water quality as reported is mainly contaminated with Fluoride, Arsenic, Iron, Nitrate, and high TDS etc. including heavy metals and pesticides. Recently, Arsenic has been reported in alarming proportion mainly in Districts Ballia, Bahraich, Basti, Bareilly, Chandauli, Ghazipur, Gorakhpur, Lakhimpur Kheeri, Siddharthnagar and Unnao.

There is no single Organization, which could own the responsibility of ground water quality assessment with a set of specific norms & standards. How the actual status of ground water quality should be assessed, what parameters should be selected for quality monitoring, what are prime causes/sources for contamination, which aquifers are polluted & up to what depth ground water quality is poor, what should be the standard monitoring & surveillance system, how it should be mitigated, these are some critical issues in context of the State, which need to be resolved through a systemic study.

Objectives of the assignment:

  • The main objective of the assignment is to develop a comprehensive Database regarding inventory of all existing Public Drinking Water Sources with GPS location and their Water Quality analysis to ascertain the suitability for domestic use and for preparation of Village Water Security Plans accordingly. This Database shall be used for implementation of GIS based Decision Support System. The Data is to be uploaded on Management Information System with Integrated GIS in the form of a Web-enabled Management Information System. The Web-enabled MIS/GIS would primarily be an online system which would act as a bridge between various district project units of the implementing agencies, thus facilitating online data feeding and management of Information and Reporting system.
  • The assignment also aims at identifying the issues pertaining to inequitable distribution of water points. Spatial distribution would identify any pocket having no/less access to drinking water.
  • The assignment also aims to identify the age of hand pumps/ Piped Water Supply Systems to identify the areas where HPs/ PWS have lived their ages. This information may be collected by local enquiry.
  • It requires capturing of GPS location, which includes the Latitude & Longitude for their geographical location and height of ground level above mean sea level for each and every existing Public Drinking Water Source, including India Mark-II Hand Pumps, besides different components of piped Water Supply Schemes, other Surface Water Bodies and Sustainability Structures/Rain Water Harvesting Schemes located in every habitation.
  • Water Quality testing, using FTKs and H2S Vials, of all the Public Drinking Water Sources including India Mark-II Hand Pumps and Public Stand Posts of Piped water supply schemes covering all the habitations in the rural areas of the State for ascertaining their suitability for drinking/domestic use.
