21m, the unconsolidated sediments by and large comprise clayey material with sub-ordinatesand horizons. Assuming ground water draft of 400 MCM, a balance of about 80 MCM maynow be available balance resources available in the Haldia region.38. In the Digha Sankarpur area, two freshwater and one brackish to saline water aquiferhorizons have been identified:1. Basal sand dominated confined aquifer system, extending from 160 m to 300 mdrilled depth with fresh water of very high quality. Salinity in this zone is from 0.6 to0.9 gm/litre and iron content is generally high.2. Middle coarse sand dominated aquifer extending between 15 and 80 m, withoccasional brackish contamination with salinity range of 4-6 gram/litre withimpermeable clay layers separating the fresh water bearing zone3. Upper dune sand sequence forming unconfined fresh water aquifer extending up to 9m with a salinity range of 0.7 to 1.1 gm/litre increasing downward. Although usedextensively in the villages, hotels and holiday homes, the water quality is poor due tocontamination of coliform bacteria and high concentration of chloride and iron andhigh hardness and alkalinity.All the aquifers are recharged by monsoon rain but the piezometric surface of the deepaquifer is depressed by 9 metres during January to March due to heavy withdrawal forcultivation. Increasing demand and drawal of ground water from the deep aquifer, there isreal threat of saline water ingression if excessive withdrawal is regulated.D. Coastal Zone Management – StatusD.1 Laws and Policies – CRZ and CMZ39. The Environment (Protection) Act, 1986 was enacted to provide an umbrella nationallegislation for protection of environment inclusive of the coastal region. The notification No.114(E) of 1991 by Ministry of Environment and Forests, Government of India under section3(1) and section 3(2) of the Act and Rules 5 (3) (D) of Environment (Protection) Rules, 1986declaring coastal stretches as coastal regulation zone (CRZ) and regulating activities in theCRZ was the first serious attempt of legislation on coastal issues. This notification along withother legislations as detailed below provides broad framework regulating activities in coastalstretches.D.1.1 The Water (Prevention and Control of Pollution) Act, 197421
