Abstract:
The existence of aquifer layer and water quality tests in Rimba Panjang, Kampar have
been explored using geoelectric resistivity method with Wenner configuration and
hydrogeochemical method. Geoelectrical method is one of geophysical methods to
understand geological condition subsurface based on resistivity value of rock types.
Hydrogeochemical method is a method for studying the chemical composition of
water. Identification of the aquifer layer was carried out on 2 tracks with a length of
each track of 100 meters. Based on the resistivity value, the subsurface lithology of
the research area consists of layers of clay, peat, sand, sandstone, and gravel to dry
gravel. Based on the results of data processing, the data interpretation using
Res2Dinv software and geological data of the surrounding area, it is known that the
subsoil conditions and the presence of groundwater aquifers in the study area with a
resistivity value of 89,2 – 1023,9 Ωm with a depth of less than 8 meters.The quality
of groundwater in this research area is classified as clean and suitable for
consumption as clean water. The results of the water quality test of the two samples
carried out showed the results for pH values of 7.53 and 8.19, BOD 10.2 mg/L and
10.6 mg/L. The two test parameters show a value below the standard of clean water
quality, which means that the water in this research area is not polluted.
