INTERPRETASI KUALITAS DAN KUANTITAS AIR BAWAH TANAH MENGGUNAKAN METODE GEOLISTRIK ATURAN SCHLUMBERGER DAN GEOKIMIA DI JALAN MANYAR SAKTI, KELURAHAN SIMPANG BARU, KECAMATAN BINA WIDYA, PEKANBARU, RIAU

Abstract

Simpang Baru Village, Bina Widya District is an area that consists a lot of community housing. Community housing is one of the potential sources of domestic waste either in the from of liquid domestic waste from septic tanks, or solid waste from housing.the waste can infiltrate into the aquifer system, which can cause groundwater pollution. The method used in this research is a geoelectric survey with Schlumberger rule with two paths, while to determine the quality of groundwater, the geochemical method was used by analyzing the parameters of turbidity, pH, TDS, conductivity and salinity. The results obtained from geoelectric method show that the Manyar Sakti area based one the measurement results of the resistivity value at the research site is interpreted for path 1 the value of the soil layer rangers from 109,84 Ωm to 1,0 Ωm with a maximum depth of 40 meters. Track 2 has a resistivity value of the soil layer which ranging from 190,39 Ωm with 1,02 Ωm a maximum depth of 44,61 meters. While the value of chemical parameters, for the pH parameter test, all samples 𝐴 = 𝜋𝑟2 acidic and dangerous if consumed in excess. For the parameters of TDS, salinity, and turbidity are considered suitable to be used, while the conductivity parameters are on the threshold of the maximum conductivity of clean water.
