INTERPRETASI AIR BAWAH TANAH DENGAN METODE GEOLISTRIK KONFIGURASI SCHLUMBERGER DI PERUMAHAN MUTIARA TENAYAN RAYA KECAMATAN TENAYAN RAYA KOTA PEKANBARU

Abstract

Research to determine the flow patterns, potential and quality of community water wells in the housing area of Mutiara Tenayan Raya, Tenayan Raya Pekanbaru District, has been conducted. This study uses the Schlumberger configuration geoelectric method with two horizontal and vertical trajectories. Processing data using Software Progress to get the depth, thickness and number of rock layers of the resistivity value was obtained. Water quality testing uses a chemical method consisting of parameters pH, TDS (Total Disolved Solid), BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), and the color of each sample of three pieces were taken at three different wells. The results of both Tracks show groundwater flowing from the first trajectories to the second trajectories. Groundwater potential in the second trajectories is greater than the first trajectories because the thickness of the second trajectories aquifer is greater than the first trajectories. Based on the results of laboratory tests, all three samples have acidic pH and the second and third samples are not suitable for use as drinking water.
