The present study investigated the relationship between resistivity values that obtained from the electrical geophysical survey and characteristics of water quality at Sinu area-NW Iraq.
The pattern of the resistivity values for the main ground water aquifer at Seno area, which represented by Al- Fatha formation are coincided with some properties of water in this aquifer that are represented (pH, TDS, SO4-2, Ca+2, HCO3-1, Na+1, K+1, No3-1), so these properties are strongly show coincidence with resistivity values, (0.8 R -0.8).
Through this proposed method, mathematical equations found to estimate the characteristics of water quality depending on the resistivity values.
