Abstract
The increment of population growth in Bambu Kuning Village, Tenayan Raya
District, Pekanbaru City, was predicted to affect the availability of underground
water in that area. This study aims to determine groundwater potential and
groundwater quality based on resistivity interpretation using the Schlumberger
configuration geoelectric method and geochemical tests. This research was
conducted on two measurement lines with a length of 200 m from North to South
and 100 m from West to East, respectively. The results of interpreting resistivity
values using software Progress show that on line 1 the soil aquifer layer is at a
depth of 43.17 – 54.93m with rock resistivity of 53.70 Ωm and on line 2 the soil
aquifer is at a depth of 28.07 – 46.43 m with rock resistivity 49.38 Ωm. The
ground water taken is the well water of residents in the study area as many as 6
sample points. Testing the quality of groundwater prodnces pH parameters
ranging from (8.0 -8.3), turbidity parameters ranging from (0.3 – 0.44) NTU,
COD parameters ranging from (2 – 26) mg/L, and BOD parameters ranging from
( 0.6 – 4) mg/L. The results of groundwater show that pH, turbidity, COD, and
BOD, agree with quality standards, for consumption.
