PENENTUAN POTENSI AIR TANAH DENGAN METODE PUMPING TEST

Abstract

The value of soil water potential at Yepupa Regency and Griyo Puspito Regency subdisditrict of Tampan in pekanbaru by using Pumping Test method is reported. The result of the measurement shows the reduction value of water soil and explosion debit on every step, data were processed by using microsoft excel to achieve the value of aquifer loss (B) and the value of well loss (C) from every measured aquifer. Achieved data is processed by formula which is used to obtain well efficiency value percentage in every explusion debit level. The result of the first location at Yepupa regency produced 32% in maximum debit and 65% in minimum expulsion debit. The second location produced 63% in minimum expulsion debit and 30% in maximum. The third location of the research showed that well efeciency value in minimum expulsion debit reached 43% while in maximum expulsion debit the value became 16%. The fourth location produced 29% in minimum expulsion debit meanwhile 15% in maximum.
