Abstract: A study concerning
the determination of the quality of river water and well water around the river
Siak using the experimental method has been investigated. This research was
conducted by measuring the electrical properties of water at a temperature of 20
̊C. The type of water used were water streams, water dug wells and water wells
drilled in obtaining seven points. Measurement of the electrical properties of
water was done by using multitester associated with power suppy, the plate of
Copper (Cu) and Zinc (Zn) as a conductor, and the glass beaker as a container
for the sample. The measurement will show voltage and current values. Based on
voltage and current values,theycan calculate the value of the electrical
properties of each sample. Results of river water has a resistance value of
2255.46 Ω, resistivity of 213.14 Ωm, conductivity of 0.00530(Ωm)-1, and power
of 3.81 x 10-5 W. The electrical properties of best water wells dug well is six
with a resistance value of 3136.46 Ω, resistivity 296.39 Ωm, conductivity of
0.00345 (Ωm)-1, and power of 7.85 x 10-5 W. Based on the results, the value of
the electrical properties of the best water is the average electrical
properties of water well three (drilled wells) with a resistance value of
3538.61 Ω, the electrical resistivity value of 334.39 Ωm, the electrical
conductivity value of 0.00341 (Ωm)-1, and electric power of 4,76x10-5W. The
water is suitable for consumption having a resistivity of 3x103 Ω, and the
electrical conductivity of (300 to 500) x10-6 (Ωm)-1. Based on the standard
resistivity and electrical conductivity, the river and well water samples are
unfit for human consumption because the values are still far from the exposure
limits.
