FOREWORD To understand spatio-temporal variations in existing hydrogeological regime, a network of Ground Water Monitoring Well (GWMW) has been set up all over West Bengal and Andaman Group of Islands by Central Ground Water Board, Eastern Region. These GWMWs are represented by various ground water abstraction structures as found suitable for prevailing aquifer systems of any area. Systematic and periodical monitoring of these GWMWs aid in identification and quantification of changes in groundwater availability and its quality, which is vital for sustainable ground water development and efficient management of ground water resources. At present a total of 888 GWMWs are monitored representing almost all the blocks of nineteen districts of the state of West Bengal. Due to inaccessibility in Andaman group of Islands, initially the task was taken up with the help of a few GWMW but gradually the number of stations has been increased to 64. However at present no GWMW has been established in Nicobar group of Islands, due to its inaccessibility. Periodic ground water level measurements were taken up four times in a year in 20112012, (i.e. in the month of April, August, November and January) in West Bengal and two times in a year (i.e. April and November) in Andaman group of Islands. The scientific officers and technical personnel of the Eastern Regional office, systematically collected field data throughout the year. This report attempts to compile the collected data during 2011-2012 and present its detailed analysis in a comprehensive manner in the form of maps and statistical analyses and brought out in two sections, where Section A forms report for West Bengal and Section B forms report for Andaman group of Islands. Water level data has been collected by officers of CGWB, ER. Chemical analysis has been carried out by chemists of Chemical lab of CGWB, ER. Compilation of this report, evaluation of data and preparation of relevant maps and their reproduction in the form of present report has been carried out by Dr. Indranil Roy, Sc. `C’. It is sincerely hoped that the appended write up, maps and basic information in this report would be very useful to the concerned beneficiaries.

ABSTRACT In West Bengal, ground water level monitoring is carried out by Central Ground Water Board, Eastern Region from 888 Ground Water Monitoring Wells covering all nineteen districts of West Bengal under different hydrogeological and agro-climatic zones during the month of April, 2011, August, 2011, November, 2011 and January, 2012. Out of 888 ground water monitoring wells, 468 are open dug wells, 226 are tube wells and the rest 194 are piezometers. In Andaman and Nicobar Islands, monitoring of water level is carried out from 64 nos. GWMSs established in different hydrogeological and agro-climatic zones. Out of 64 GWMS, 61 wells are open dug well and rest three are bore well. In Kolkata City, monthly monitoring of water level is carried out using 23 nos. GWMSs. Collected water level data were statistically analyzed and relevant maps depicting ground water scenario corresponding to various measurements were prepared. All datasets were compared and analyzed with pre-monsoon measurements and also with dataset of same period for previous year. Mean depth-to-water level for the period 2001-2011 was compared with corresponding measurements and analyzed to delineate the behavior of water levels. Status of Ground Water Monitoring Stations and number of the wells monitored during four water level measurements are also prepared. Statistical data incorporate ranges of water levels and water level fluctuations, minimum and maximum values of water level, number of wells measured, percentage of monitoring stations falling in different ranges with district-wise breakup in different pre-defined categories in compliance with national guideline. Along with the general well information, depth to water level data of all network hydrograph stations, are also presented. The water samples collected during April 2011 were chemically analyzed and the data generated has been presented. Maps pertaining to Chloride, EC, and Iron distribution have been prepared. Present report has been prepared on groundwater scenario of West Bengal and Andaman and Nicobar Islands reflecting the status of groundwater regime as revealed through ground water level and quality monitoring during 2011-12.

GROUND WATER YEAR BOOK OF WEST BENGAL (2011 – 2012) 1.0
INTRODUCTION Periodical monitoring of ground water regime covering different hydrogeomorphic, hydrogeological units is an effort to acquire information on behaviour of ground water levels, chemical quality and temperature of formation water through representative sampling. The process is essential in both spatial and temporal domain, to consolidate a detailed knowledge about ground water scenario of an area with respect to its behaviour, availability and quality. Thus, data so collected during monitoring becomes one of the most important inputs for an holistic ground water management. Monitoring is carried out by establishing suitable Ground Water Monitoring Stations (GWMS) based on geomorphology, geology, hydrogeology and status of ground water resource of the area with a view to observe the trend of water level and change of chemical quality with space and time. It is also essential for estimation of ground water resources and to demarcate the water logging as well as drought prone areas. In West Bengal, ground water monitoring was started since 1976 when most of the ground water structures were mainly dug wells and the development of the ground water resource was very limited. It is only after 1985, actual ground water development started in irrigational sector and took its full swing from 90s. Accordingly, network stations (GWMS) for monitoring of water level data were also changed in different periods. However, from late nineties, these old wells are being replaced by well-defined piezometers in phased manner with an expectation that in near future, this effort will provide better result. 1.1
BACKGROUND
The Central Ground Water Board, Eastern Region, is at present monitoring 886 operational GWMS (network hydrograph stations) to delineate the behaviour of ground water level in spatio-temporal domain, covering entire state of West Bengal four times a
1
year, viz. January (from 1st to 10th), April (from 20th to 30th), August (from 20th to 30th) and November (from 1st to 10th). The district-wise status of GWMS in West Bengal during the period from April 2011 to January 2012 is given in Table 1. The locations of GWMW are shown in Plate - I. To get a detailed water level scenario in the urban area especially in metro city, CGWB, Eastern Region, is also monitoring monthly measurement from 23 monitoring stations in Kolkata City (Plate - II). The district-wise water level data of GWMW for the period April, 2011; August 2011; November 2011 and January 2012 are given in Annexure - I. Trends of water level of West Bengal (2002-2012) are given in Annexure - II. The results of chemical analysis of water samples collected during April 2011 are also discussed and analytical data are given in Annexure - III. The water level data of GWMW of Kolkata city has been given in Annexure - IV.

PHYSIOGRAPHY AND DRAINAGE In general the state of West Bengal is a flat terrain, crisscrossed with rivers except the Himalayan foothills in the north and Chotanagpur plateau in the south-west. Southern flowing Ganga River and its numerous tributaries & distributaries mainly drain the State. The Ganga River system encompasses the catchment areas of the Mahananda, Jalangi, Bhairab etc. in the eastern part and the Mayurakshi, Ajoy, Damodar, Dwarakeshwar and Kasai in the western part. The Teesta, Torsa and Jaldhaka streams of the Brahmaputra river system originate in the Himalayas and drain the northern part of the State. Beside these, there is a small independent river basin, namely Subarnarekha basin covering southwestern part of the State in Medinipur district. Physiographically, the area incorporates extra – peninsular region of the north, peninsular mass of the south – west, and alluvial and deltaic plains of the south and south-east. The State can be broadly divided into four distinct physiographical divisions as: (i)
Himalayan Region comprising Darjeeling, Jalpaiguri and Kochbehar districts;
(ii)
Eastern fringe of Chottanagpur Plateau comprising districts of Puruliya, western parts of Barddhaman, Paschim Medinipur, Birbhum and Bankura district; 2
(iii)
Coastal areas comprising of South 24 Parganas district and small part of North 24 Parganas, Purba Medinipur and Howrah districts;
(iv)
Alluvial terrains falling in the remaining parts of the state.
In each of above four areas ground water regime behaves differently.

HYDROMETEOROLOGY The general climate of the state, except the Himalayan zone which lies in the extreme northern part, is tropical. The tropic of cancer passes across the middle of the districts of Nadia and Barddhaman and the northern part of the districts of Bankura and Purulia. The normal annual rainfall in the state varies from 1276 to 3608 mm. The Himalayan region in the northern parts of the state receives the maximum rainfall. The Average rainfall in different districts of West Bengal is presented in Table I. Table I. Normal Rainfall distribution in West Bengal

GEOLOGY Diverse rock types ranging from Archaean metamorphites to Quaternary unconsolidated sediments cover the State of West Bengal. Approximately 75 percent of the area is 3
covered by alluvial and deltaic deposits of Sub – Recent to Recent time and the remaining part abounds in a wide variety of hard rocks.

HYDROGEOLOGY OF WEST BENGAL The entire West Bengal state can be grouped under two broad hydrogeological units, namely,
Fissured formation; and
Porous Formation.
4
5.1
FISSURED FORMATION
Proterozoic gneisses and schists, Gondwana Super group of rock and Siwalik rocks of Extra- Peninsular region in Darjeeling and Jalpaiguri districts to the north and Archaean to Proterozoic gneisses and schists in Peninsular region occurring in western part of Barddhaman, Bankura, Birbhum and northern part of Medinipur and whole of Purulia districts and Gondwana and Purana sediments (Susunia quartzite of Bankura) deposited in the intracratonic basins in the shield area and Rajmahal basaltic traps in the eastern fringe area of the shield fall under fissured formation. Groundwater in this formation occurs in weathered mantle and in the zone of secondary porosity. 5.2
POROUS FORMATIONS
Nearly two-third of the state is occupied by a thick pile of unconsolidated sediments laid down by the Ganga-Brahmaputra River system, the thickness of which increases from marginal platform area in the west towards the east and southeast in the central and southern part of the basin following the configuration of Bengal Basin. These unconsolidated sediments are made up of succession of clay, silt, sand and gravel of Quaternary age overlying Mio-Pliocene sediments. The Quaternary sediments are made up of recent and older alluvium. Occurrence and movement of ground water in this hydrogeological unit is controlled by the primary porosities of the sediments. In West Bengal aquifer characteristic varies considerably from north to south and west to east. Out of 341 blocks by and large most of the areas show aquifer under both water table as well as confined condition. The entire coastal area consist of 59 blocks is under confined condition. (29 blocks in S 24 Parganas, 5 blocks in N 24 Parganas, 9 blocks in Howrah and 16 blocks in Purba Medinipur). Kolkata is also under confined condition. Aquifer conditions in different districts are summarised below in Table III. Table III. Aquifer condition in west Bengal District

m /hr, with maximum discharge of 22 3 m /hr. In the submontane zone of Himalaya the sediments consist of unassorted materials varying from boulders to sand of various grades. The aquifers are having deep water table & are characterised by high seasonal variations of water level to the tune of 10-12m. Recent exploration identified the potential granular zones within the depth range of 150mbgl 3 capable of yielding up to 68m /hr. Ground water under semi-confined to confined condition below a blanket of about 60 m thick clay bed. Saturated granular zone of discontinuous nature generally occurs in the depth span of 65110 m, which is capable of yielding up to 3 50 m /hr. The maximum thickness of Older Alluvium is within 50 m, which is capped by laterites. Individual aquifer in older alluvium is of limited thickness and discontinuous in nature has poor yield prospect. Exploration in the tract has indicated the presence of unconsolidated to semi consolidated Tertiary gravel & sand stone, under the Older Alluvium, in the depth zone of 100-140 mbgl, which is porous in nature and has the yield 3 prospect of 180 m /hr. In Birbhum district, aquifers beyond 136 mbgl up to the drilled depth of 350 mbgl in the Tertiary formation are found under auto-flow condition. Ground water occurs both under unconfined & confined condition within the explored depth of maximum 600mbgl. Aquifers are fairly thick & regionally extensive with large yield prospect of 3 about 150m /hr. Occurrence of Arsenic in ground water in the depth span of 20-80 mbgl restricted mainly in the eastern part of Bhagirathi river has posed a serious problem. In view of the situation exploration work has been undertaken in the arsenic infested areas & arsenic free deeper aquifers could be identified beneath a thick clay bed in Nadia district. Fresh ground water bearing aquifer occurring in varying depth ranges within 120-360 mbgl within the drilled depth of

600 mbgl have been established. The fresh group of aquifers is sandwiched between saline/brackish aquifer. The top saline/ brackish aquifer lies within the depth span of 20-180m with maximum depth of 320mbgl in the extreme south. Suitably constructed tubewell tapping 35m cumulative thicknesses can yield 1003 150m /hr. Shallow fresh water aquifers occur in present day dunes in Digha Ramnagar area of East Medinipur district down to the depth of 9 mbgl & in levee deposit within 50mbgl in Baruipur Sonarpur - Bhangar - Caning tract in South 24 Parganas. High Concentration of As in ground water is reported in this levee deposit.
CRITERIA FOR FIXING GWMS Ground water monitoring is mainly done in the water table aquifer to categorize an area having excess or less withdrawal. This is useful to estimate the dynamic ground water resources and to demarcate the water logging as well as drought prone areas. To understand the correct water table aquifer in an area geomorphology and geology play a vital role. Therefore, for fixing GWMS in a district/block one has to consider the following factors: 6.1
FIXING GWMW BASED ON GEOMORPHLOGY
At least one GWMW in each geomorphic unit of more than 50 sq. km extent. 6.2
FIXING GWMW BASED ON GEOLOGY
Minimum one GWMW in each geologic unit having more than 150 sq. km. in hard rock areas and 200 sq. km. in soft rock area extension. 6.3
FIXING GWMW BASED ON STATUS OF GROUND WATER RESOURCE Category

SCENARIO OF WATER LEVELS IN KOLKATA CITY DURING THE GROUND WATER YEAR 2011 – 2012 Kolkata city area is underlain by Quaternary sediments consisting of silt, clay, various grades of sand, gravel and occasional pebbles, deposited in deltaic environment by Ganga- Bhagirathi river system. Here ground water occurs under confined condition and the piezometric level is significantly deep, ranging between 10.68 & 19.00 mbgl during pre-monsoon period and between 8.25 & 18.25 mbgl during post-monsoon period. In major part of the city, piezometric level generally varies from 14.50 – 16.50 m bgl. This is due to huge withdrawal of groundwater for domestic and industrial uses. The monthly piezometric level during 2011-12 is presented in Annexure IV. Depth to water level map of KMC area during pre-monsoon and post-monsoon period is given in 20
Plate-XXI. Hydrographs of KMC area are given in Plate-XXIII. Depth-to-water level categorization of pre and post monsoon is presented in Table-17. Trend in piezometric level has been analysed statistically for the decadal Pre-monsoon, Post-monsoon fluctuation (2001-2011), and has been summarised in Table-18. Pre-monsoon water level (Piezometric) trend fluctuates in the range of 0.001- 0.71 m/yr in rising category and 0.03- 0.5 m/yr in falling category. Post-monsoon water level (Piezometric) trend fluctuates in the range of 0.02- 0.4 m in/yr in rising category and 0.02- 1.03 m/yr in falling category. However falling trend is more significant as has been observed in 17 wells in contrast to 07 wells showing rising trend during pre-monsoon period and in 18 wells in contrast to 06 wells showing rising trend during post-monsoon period. Falling trend in Salt lake area is very significant.
10.0 HYDROCHEMISTRY The chemical quality of groundwater is dependent on the source of water and on the course over which it flow. The chemical analysis data of ground water samples collected during the period April 2011 from Ground Water Monitoring wells are given in Annexure IV. Ground water samples throughout the State found to be slightly alkaline. In general ground water is fresh. Quality of ground water in northern part of the state covering Kochbehar, Jalpaiguri and Darjeeling districts is much fresh with low mineral contents having electrical conductance varied from 82 to 918 µS/cm at 250C. Comparatively in major parts of Malda, Dakshin & Uttar Dinajpur districts, the dissolved salts concentration found to be relatively high and maximum value of 3010 µS/cm observed at Sunderpur of Dakshin Dinajpur district. In The coastal belt of Purba Medinipur, Howrah, South-24 Parganas and North 24 Parganas districts the upper aquifer is brackish in many of the places. EC value commonly ranges between 2000-3500 µS/cm. However it may go up to 6950 µS/cm as in Baganda, Haora. Ground water is fresh in the deeper confined aquifers.
Distribution of EC (Apr-2011) is given in Plate - XVIII.
Distribution of Chloride (Cl-) and Iron (Fe) during pre-monsoon season (Apr-2011) is
21
given in Plate - XIX and Plate - XX respectively. Range of various parameters is given below. Parameters

Fluoride concentration more than 1.5mg/L, which is recommended maximum permissible limit (BIS), has been found in few places of Birbhum, Bankura, Puruliya, , Murshidabad, Malda, Dakshin & Uttar Dinajpur, N-24 Parganas and Nadia districts. Overall higher concentration has been observed in Birbhum District. However the occurrence is sporadic. On the other hand, occurrence of arsenic, as a pollutant in groundwater, has been found in a linear tract, extending NNW-SSE from Kaliachak block of Malda district through the eastern part of Murshidabad, Nadia, eastern fringe of Bardhaman, Hugli, North 24 Parganas, South 24 Parganas and Howrah districts covering seventy-nine administrative blocks. The concentration of arsenic above permissible limit (0.01mg/l) has been found sporadically in the aquifers in the depth span of 20 to 100 m bgl, which is mainly restricted to the area lying east of river Bhagirathi. Thus it is observed that the quality of ground water in shallow aquifers in the entire state of West Bengal is suitable for drinking, irrigation and industrial purposes except arsenic and fluoride infested areas.
22
In Kolkata Municipality (KMC) Area ground water is mainly of bicarbonate and chloride type. Ground water in the extreme northern, eastern and western part is brackish with chloride and EC exceeding 500mg/l and 2000 µS/cm respectively and marginal to good in the rest of the area. The analysed chemical data are presented in Annexure-V.

GROUND WATER YEAR BOOK OF ANDAMAN AND NICOBAR ISLANDS 2011 - 2012 1.0
INTRODUCTION Groundwater monitoring data form an important input for judicial ground water management & development. Yearly two water level measurements during pre & post
monsoon period in the month of April and November respectively are taken in Andaman & Nicobar Islands. Since Andaman & Nicobar Islands experienced heavy
rainfall during the month of November, post monsoon water level is generally taken during the month of December. At present, 64 operational network hydrograph
stations are monitored in Andaman district (PLATE-B I) in various hydrogeological units and agro-climatic zones two times a year, viz. May and December. In Nicobar district, no network hydrograph stations have been established till date. 2.0
GENERAL FEATURES The Andaman and Nicobar Islands (A & N Islands) is one of the Union Territories of India and are situated as a dissected chain in an arcuate fashion oriented N-S in the
Bay of Bengal off the Eastern Coast of India. These Islands are extended between 6° to 14° N and 92° to 94° E in between Myanmar and Sumatra (Indonesia) over a distance of 780 km. This Union Territory is divided into two districts, i.e. Andaman and
Nicobar.The northern group of Islands forms the Andaman district, is further subdivided into three parts namely, North Andaman, Middle Andaman And South
Andaman. The southern group of islands is separated from the northern group by about 140 km deep sea, the 10° channel, forms the Nicobar district. 3.0
TOPOGRAPHY The islands forming Great Andaman consist of a mass of hills enclosing very narrow valleys, the whole covered by dense tropical jungle. The hills rise, to a considerable
elevation, the heights peak being in the North Andaman, Saddle Peak (732m); in the Middle Andaman, Mount Diavolo behind Cuthbert Bay (511m); in the South Andaman, Koiob (459m), Mount Harriet (364m) and the Cholunga range (324m); and in Rutland 156
Island, Ford's Peak (433m). Little Andaman is practically flat. As such there are no rivers, however few perennial streams are present in the islands. Barring a few small Islands in the Nicobar group, all the others have undulating terrain with main ridges
running North-South. There are also spurs running East - West in between the main ridges. The submerged valleys form deep inlets and creeks. Flatlands are few and
perennial streams non-existent in most of the Islands except in Great Nicobar where there are 5 perennial rivers. Coral reefs surround most of the islands. 4.0
PHYSIOGRAPHY These Islands are in general characterized by undulating and rugged topography. Physiographically these Islands can be subdivided into three main parts I)
Moderate to steep hill ranges
II)
Intermontane narrow valley
III)
Coastal tracts including swamps
The huge ranges generally covered by dense forest. 5.0
HARBOURS Coasts are deeply indented, giving existence to a number of safe harbours, which are often surrounded by mangrove swamps.
6.0
DRAINAGE Perennial streams of the status of river is absent in A & N Islands except in Kalpong in
the North Andaman. In Great Nicobar, the important perennial streams are Galathea, Jubilee, Dark Anaing, Dark Tayal, Amrit Kaur. 7.0
SOILS Soils of Andaman and Nicobar Islands have been classified into 3 orders, i.e. Entisols, Inceptisols and Alfisols. The main agricultural soils are found in the valleys and have
alluvial and colluvial origin. The coastal areas prone to tidal floods may have acid
157
sulphate soils. On the whole, soils of these Islands are nutritionally poor and their organic matter content is on decline. 8.0
CLIMATE The climate of Andaman and Nicobar Islands is described as humid Tropical Climate. The Islands are situated in the Hot or Torrid Zone. Nearly 86 percent of total area in these Islands is covered by forest. There are only two seasons viz. Rainy Season and
Summer Season and virtually there is no Winter Season. Islands are visited by South West and North - East monsoons during the period from May to December. Average
annual rainfall in these Islands is 3000 mm. The period from January to May is Summer Season. The mean relative humidity is 79% to 82%. The mean maximum temperature is 30.2oC and mean minimum temperature is 23.8oC. 9.0
GEOLOGY The Islands are composed mainly of thick Eocene sediments consist of Pre-Tertiary sandstone, siltstone and shale with intrusions of basic and ultra-basic igneous rocks. In
the geologically Younger Richie’s archipelago, calcareous sand stones are more common. 10.0
HYDROGEOLOGY The Andaman & Nicobar group of Islands are underlain by Late Cretaceous igneous
rocks - the 'Ophiolite Suite', marine sedimentary group of Palaeocene to Oligocene
age and Recent to Sub-Recent beach sand, mangrove clay, alluvium and coralline formations. The Ophiolite suite comprises a wide variety of acidic to ultra basic
plutonic rocks and their serpentinised equivalents and essentially basic volcanic rocks occur in South, Middle & North Andaman, in sporadic patches of Little Andaman, Kamorta and Bampooka Islands in Nicobar group. The marine sedimentaries comprise greywakes, graded sandstones, siltstones, black shales and volcanogenic sediments.
These fine-grained deep-sea deposits are generally having predominantly clayey particles. The coralline formations are observable in coral islands (atolls) and they also occur in the fringe areas of the sedimentary and igneous formations and form the 158
narrow beaches encircling the islands. The ophiolite and marine sedimentaries have
undergone different phases of folding, faulting and upliftment; which is responsible for the development of fractures and fissures, as a result infiltrated rainwater percolates downwards.
Marine sedimentary rocks are located to an anomalous admixture of sand and clay where clayey residue are predominating since clayey product is poor water yielder, these sedimentary rocks, in majority of the cases, do not form potential aquifer system both in shallow and deeper horizons. Bore wells are not feasible in these formations and the yield of dugwells with a diameter of 4.5 to 5m and 6m depth
tapping the weathered mantle varies from 3000 to 5000 lpd. Depth to water level in these formations varies from 0.2 to 4.4 mbgl. All the borehole drilled in these
formations were unsuccessful except one borehole at Prothrapore, which is yielding brackish water (5500 EC) having discharge 17000 lph. The igneous rocks also do not form potential aquifers, however in comparison to the sedimentaries they yield moderately. These rocks form aquifer both in weathered
mantle and fractured basement rocks which are generally developed through dug well, ponds and private bore wells. Out of six successful bore wells drilled by CGWB, 5
nos. were constructed in igneous rock. The success may be due to partial clogging of fractures with clayey residue where it is fully sealing the fracture conduits in sedimentaries. The well at Calicut, constructed by CGWB, is now the only supplying well of APWD, A & N Administration. The fracture conduit is conjectured upto 45m depth. The discharge of Calicut well is 45000 lph. The coralline limestone formations also form potential aquifer. They are distributed at
shallow horizon and are developed through dug wells in many islands like Car Nicobar,
Katchal, Neil, Havelock etc. Yield of these dugwells (commonly of 5m dia, 6m depth) varies from 15000 to 1 lakh lpd. Recent studies of CGWB have revealed that the valley-fill alluvial deposits consisting
of boulders, pebbles, cobbles, and sand, carry lot of water and saturate the near
surface aquifer through out the year. Hence, such valley-fill deposits form potential 159
aquifers in A & N Islands. CGWB constructed exploratory well at Beadnabad on valleyfill deposit, down to the depth of 17m, yielded 72000 lph water. This also indicated
that Artificial Recharge and Conservation program might be successful in those areas. Pilot scale implementations of such structures by CGWB proved it highly successful.
Depth to water level data of various network stations for the period April, 2010 and December, 2010 is given in Annexure- B I. 11.0
SCENARIO OF DEPTH TO WATER LEVELS IN ANDAMAN DURING GROUND WATER YEAR 2010 – 2011 11.1
APRIL, 2011
The Depth to water level generally varies, between 0-2m, 2-5m and 5-10m below
ground level. Majority of the wells show water level between 2-5m (96.7%). The minimum water level at ground-level was recorded at Kaushlyanagar of Middle Andaman and maximum 8.24 mbgl at Calicut borewell of South Andaman. The
distribution of network hydrograph stations in different ranges of depth to water level is presented in Table - B1. 11.2
November, 2011
The Depth to water level generally varies between 0-2m, 2-5m and 5-10m below ground level. Out of 64 wells measured, water level in 42 wells varies in the range of
0-2 mbgl, in 10 wells in the range of 2-5 m bgl and in 02 wells in the range of 5-10 m bgl. The minimum water level was at 0.15 mbgl and recorded at Durgapur of North
Andaman and maximum water level i.e. 7.82 mbgl at Calicut borewell of South
Andaman. The distribution of network hydrograph stations in different ranges of depth to water level is presented in Table - B2. 12.0
FLUCTUATION IN WATER LEVEL IN ANDAMAN DURING GROUND WATER YEAR 2011 – 2012 The pre-monsoon water levels of April, 2011 has been compared with post-monsoon water levels of November 2011 to delineate the impact of rainfall as well as ground
water development on ground water regime in the state during the above period. 160
Fluctuations in water levels for the periods of April 2010 and April 2011, and December 2010 and November 2011 have also been analyzed. 12.1
WATER LEVEL FLUCTUATION BETWEEN APRIL 2011 AND NOVEMBER 2011
The seasonal fluctuation in water level for April 2011 compared with November 2011 has been done and distribution of network hydrograph stations in different ranges of water level fluctuation is presented in Table - B3.
The fluctuation data of November 2011 in comparison with April 2011 shows a rise in
water level in 63.3% wells and fall in 36.7% wells. However, in all cases the rise or fall in water level is restricted within 0-2m. 12.2
WATER LEVEL FLUCTUATION BETWEEN APRIL 2010 AND APRIL 2011
The fluctuation in water level between April 2010 and April 2011 indicates the net
status of ground water conditions during the previous and current summer periods. Distribution of network hydrograph stations in different ranges of water level fluctuation is presented in Table - B4. The total analysed (60 nos.) data of shows that scenario is dominated by rise in water
level in the range of 0-2 m (55%), 2-4 m (30%) and 20 (m No. %
