Abstract

Identification of groundwater at Graha Mustamindo Permai 3 Housing Complex, Rimba Panjang Village, District Tambang, Kampar Regency, Riau Province has been done. The method used in this study is the geoelectric method with Schlumberger configuration. Identification of the aquifer layer was carried out on 2 tracking lines with a length of 100 meters. Measurement data were processed using software Progress. The results of data processing of track 1 and 2 show a maximum depth of 35 meters. The results of aquifer interpretation on track 1 are at depth of (3.90–11,13) meters with a resistivity value of 246.51 Ω.m. Track 2 is at a depth of (7.43–14.66) meters with a resistivity value of 142.15 Ω.m. Soil water samples were tested for pH parameters. All water samples have acid levels with an average pH of 5. So that it can cause rust an inner surface of water pipe resulting smelly water therefore the water cannot be consumed by the people.

Abstract

The effect of seawater intrusion on groundwater has been carried out in Tanjung Kapal Village, Rupat District by using the geoelectric method of the Schlumberger configuration. This study aims to determine the resistivity value, layer depth, thickness of the groundwater layer, determine the effect of seawater intrusion on groundwater and determine the water quality of residents' wells in Tanjung Kapal Village. This study took 5 samples and tested for pH and salinity parameters to determine water quality. The results of the research on line 1 had a resistivity value range between 1.13 - 0.04 Ωm depth of 0.70 - 36 m and the line 2 had a resistivity value range between 11.07 - 0.10 Ωm depth of 3.12 - 42 m. On line 1 is affected by seawater intrusion in layer 2 which has a resistivity value of 0.60 Ωm with a depth of 0.70 – 3.42 m. Line 2 is affected by seawater intrusion in layer 3 which has a resistivity value of 3.53 Ωm with a depth of 7.22 – 13.42 m. The influence of seawater intrusion causes the groundwater around the site to have brackish due to the relatively low salt content. Water quality based on pH parameters of 20% is not in accordance with quality standards and salinity parameters of 100% brackish water.
