Pengaruh Penambangan Bahan Galian C terhadap Hidrogeologi di Desa Beras Sekata Kecamatan Sunggal Kabupaten Deli Serdang Propinsi Sumatera Utara

Abstract

Business activity mining of dig materials of C is generally corducted by using the following steps : peel of cover coat, dig of material, transportation processing I wash. For the activity of dig used by appliance of Back Hoe, after material obtained by hence conducted by transportation go to lauderette by using truck dump. At activity of dig / peel of dig materials of C conducted by peel of flake and unloading of substratum. Peel of this flake will give crosscut influence of ground water face. At the same time with amputation of the ground water r face-cause degradation of ground water face. Other effect of dig of dig materials of C is land become hairlessly, degradation of river base, decreasing of it ground absorpsion to water and there are holes him which loaded by water ( pool). In this research, researcher do research of influence of mining of dig materials of C to hidrogeologi in Countyside Rice Word Dstrict of Sunggal. Method the used is method survey with direct perception is field as primary data and data of sekunder. From result of research known that mining of dig materials of C have an effect on to degradation of ground water face and water quality. From result of test pumping of well of S-1, S-2, S-3 obtained by degradation of ground water face from 70 - 108 cm and water debit decrease which initialy 1-2 - Z Iitre per second become 0,055 - 0,062 per second. Result of test of is quality of water there are change of colour and turbudity at surface water and groud water effect of mining of dig of C and wash of material. To people around exploiting ground water for household better at coat of tufa riodasit considering the nature of good coat as akifer which consist of particle of tufa fairish is refine.
