GROUND WATER CONTROL AND REGULATION Number of OE blocks Nil No.of Critical blocks Nil No.of blocks notified Nil 1.0 Introduction: Khurda district with an area of 2813 sq km is bounded between latitudes 190 40’ N and 200 27’ N and longitudes 840 56’ E and 860 05’ E. It is bounded in the north and northeast by Cuttack district, on the west and southwest by Nayagarh and Ganjam districts, on the southeast by Chilika Lake and Puri district. The Population of the district as per 2001 census is 18,78,000, which is 5.10 % of the total population of the state. The male and female population of the district is 9,87,000 & 8,91,000 respectively. The density of the population is 667 per sq. km. The total literate person of the district is 13,11,000. The district is divided in to 2 subdivisions, namely Bhubaneswar and Khurda which are further subdivided in to 10 C.D blocks such as Bhubaneswar, Jatni, Balipatna, Balianta, Khurda, Bolagarh, Begunia, Tangi, Banpur and Chilika. The district headquarter is connected to all the block headquarters and important towns by all weather roads. The district is drained by a number of streams which are mostly tributaries and distributaries of the river Mahanadi and a few other streams discharging in to lake Chilika. The important distributaries of Mahanadi are the Kuakhai, Bhargabi, Kushabhadra and the Daya River. The tributaries of the Mahanadi are the Ran and Kalijiri. The streams draining the southern parts of the district are Sulia, Kharia and the Kusumi. All the streams are ephemeral and effluent in nature. Chilika, the largest salt water lake of India is situated in the southeastern part of the district. Systematic ground water survey was first carried out by the geologists of the Geological Survey of India and later completed by Central Ground Water Board. Subsequently reappraisal hydrogeological survey was carried out in different parts of the district during 88-89, 91-92, and 95-96 by CGWB. Under the ground water exploration programme a considerable number of exploratory boreholes were drilled by CGWB. Besides these quite a few numbers of tube wells were also constructed by CGWB on deposit basis for drinking water supply. 2. Climate & Rainfall: The district is characterized by a tropical monsoon climate having three distinct seasons in a year, viz winter, summer and rainy seasons. May is the hottest month with mean daily maximum temp of 380 C, while December is the coldest month with mean daily temperature of 15.70 C. The normal annual rainfall is 1449.1mm & the annual average rainfall is 1436.1mm. The relative humidity varies from 48 to 85 % at Bhubaneswar. The mean monthly potential evapotranspiration values of the district ranges from 57mm in January to 284mm in May. 3. Geomorphological Set up: Based on the physiographic set up, the district may be broadly divided in to four natural divisions such as (a) Coastal sand dune (b) Alluvial plain, (c) Lateritic upland and (d) Hilly terrain. The dunes having limited width occur along the Chilika coast discontinuously. These deposits are fluvio aeoline in origin and are of longitudinal type. Alluvial plain is the most potential hydrogeomorphic unit. It occurs as narrow strip along Chilika coast in the south east & along the courses of major rivers. The Alluvial plain in the northeast is a part of Mahanadi delta system. The lateritic upland constitutes the major parts of the district. This forms an undulating terrain covered with lateritic capping over Gondwana sand stone and Precambrian rocks. The hilly terrain is prominent in southwestern and western part. The area is underlain by Precambrian hard rocks and major part of this terrain is capped by laterities and lateritic gravels. The subunits in this terrain are (a) shallow buried pediplain (b) Moderately buried pediment (c) pediments (d) intermontane valley (e) residual hills (f) structural hills etc. Soil & Landuse: There are three types of soil generally found in the district 1) Alfisols 2) Ultisols 3) Entisols Alfisols: The deltaic alluvial soil in the eastern part of the district and the red loamy soils in the northwestern part of the district come under this class. It consists of a wide range of soils including mixed red and black soils, red earth, red loamy soils, red sandy soils, red gravelly soils and other alluvial soils. The red soils are light textured, usually devoid of lime concretions deficient in nitrogen, phosphate & organic matter. The PH of the soil varies from 6.5 to 7.3. These soils are suitable for cultivation of paddy and other crops. Ultisols: These include laterite & lateritic soil, red and yellow soils of the northern and north central part of the district. They are characterized by low contents of Nitrogen, Phosphate, Potassium & Organic matter. The PH of the soils ranges from 4.5 to 6.0. Due to granular nature of these soils cultivation is possible immediately after heavy rains without the danger of any unsatisfactory physical state. Entisols: these include the coastal alluvial soils along the Chilika lake and younger alluvial soils in the central part of the district. The texture in general is sandy to loamy and soils in general are deficient in nitrogen, phosphoric acid and humus. These soils are suitable for wide variety of crops including paddy. 4.0 Ground Water Scenario 4.1 Hydrogeology: Aquifer system of the area may be divided in to (a) fissured (b) porous types based on the lithological characteristics of the area. (a) Fissured formation: The Precambrian crystalline rocks which mainly consists of granite and granite gneiss, Khondalites, Charnockites and Anothosites occupy major parts of the district covering western as well as central and parts of eastern sector of the district. Ground water in these rock types occurs under unconfined conditions within weathered residuum and under semi confined to confined conditions in fractures at greater depths. The thickness of weathered residuum varies from negligible to 35/40m depending on rock types. The thickness of the weathered zone is minimum in Charnockites and Anothosites while the same is maximum in Khondalites. These weathered zones form shallow aquifer where ground water occurs under unconfined conditions. The average yield of dug wells in granitic rocks is around 20 to 22 m3/day with the maximum around 36 to 40 m3/day. In other hard rocks the yield is restricted within 25 m3/day with the average value around 12 to 15 m3/day. (b) Porous formation: The porous formation in the district are a) Semi-consolidated Athagarh formation of upper Gondwana Group b) Quarternary alluvium and upper Tertiary sediments and also laterites and lateritic gravels with limited extent with respect to time and space. (a) Athagarh formation: This aquifer system occurs at shallow as well as deeper depths, are mainly formed of sandstones.
