ANALISIS DISTRIBUSI PARAMETER FISIS AIR BAWAH TANAH PADA PERUMAHAN DI SEKITAR KAWASAN PABRIK KARET PT. P&P BANGKINANG KECAMATAN MARPOYAN DAMAI KOTA PEKANBARU

Abstract

Analysis of distribution for the physical parameters of ground water in the housing around the area of rubber factory PT. P & P Bangkinang Marpoyan Damai Pekanbaru has been carried out by using Radials methods about 400 m surrounding a factory. The physical parameters level of ground water include conductivity, resistivity, and salinity measured by coordinate points as much as 10 points. The recorded data of physical parameters level of ground water were input into software "surfer 11" to be processed in order to obtain a map of contour levels of physical parameters of ground water. The results showed that the highest level of conductivity is originated from the type of ring wells with the value of 0.0273 (1/ohm.m) exceeding the threshold of ground water quality, and the lowest level of conductivity is 0.00488 (1/ohm.m) comes from the borehole. The lowest resistivity level is 36.63 ohm.m from the ring wells and the highest of 204.92 ohm.m comes from the borehole. The highest salinity level of 1.5 gr/l exceeding the ground water quality from ring wells and the lowest level of 0.5 gr/l is originated from the borehole. The results of this study showed that the ground water on ring wells generally has been polluted by waste of rubber factory.
