Abstract:
Research to determine the flow patterns, potential and quality of community water wells in the
housing area of Mutiara Tenayan Raya, Tenayan Raya Pekanbaru District, has been conducted.
This study uses the Schlumberger configuration geoelectric method with two horizontal and
vertical trajectories. Processing data using Software Progress to get the depth, thickness and
number of rock layers of the resistivity value was obtained. Water quality testing uses a chemical
method consisting of parameters pH, TDS (Total Disolved Solid), BOD (Biochemical Oxygen
Demand), COD (Chemical Oxygen Demand), and the color of each sample of three pieces were
taken at three different wells. The results of both Tracks show groundwater flowing from the first
trajectories to the second trajectories. Groundwater potential in the second trajectories is greater
than the first trajectories because the thickness of the second trajectories aquifer is greater than
the first trajectories. Based on the results of laboratory tests, all three samples have acidic pH and
the second and third samples are not suitable for use as drinking water.
