The scope of the present study is broadly within the framework of National Aquifer
Mapping Management Programme (NAQUIM) being implemented by CGWB. There
are four major components of this activity viz.: (i) Data gap analysis (ii) Data generation
(iii) data collection / compilation and (iv) Preparation of aquifer maps and management
plan to achieve the primary objective. Data compilation included synthesis of database
of various agencies, such as the Survey of India, Geological Survey of India of the Union
Govt. and offices of the Govt. of West Bengal (W.B.), computerization and analyses of all
acquired data, and preparation of data bases of different themes. Identification of Data
Gap included ascertaining requirement for further data generation in respect of hydrogeological, geophysical, chemical, hydrological, hydro-meteorological studies, etc.
Relevant data in respect of the said subjects have been collected from different
authorities, viz. Public Health Engineering Dept., State Water Investigation Dept., Agri.-
Irrigation Dept., Bureau of economics Statistics, Land Land Reforms Dept., Data of
Indian Meteorological Dept., National Bureau of Soil Survey Land Use Planning, etc. of
Govt. of India have also been used. The existing data of hydro-geological data including
those of exploratory wells, piezometers, slim holes, etc. by erstwhile E.T.O., CGWB as
well as chemical quality data including trace elements in ground water, either by in-situ
or out-sourcing, lying in the Central Ground Water Board, Eastern Region have been

thoroughly studied. Besides, data have been generated by hydro-geological surveys and
collection of water samples, followed by their laboratory analyses for all major
parameters. Additional data pertaining to sub-surface lithology and aquifer parameters
were obtained through site specific drilling of exploratory wells, pumping tests, etc.
