This research was carried out to investigate the physicochemical parameters of livestock drinking water samples collected from Falfal, Degehabur and Bulale areas in Somali regional state of Ethiopia. The objective of this research was to analyze the physicochemical parameters of water ponds used for livestock drink. The result was recorded that, the pH, Temperature, Total Dissolved Solid and Total hardness was 7.17°C ± 0.03°C, 22.51°C ± 0.18°C, 17.50 ± 2.60 mg/L and 825.22 ± 92.18 mg/L, respectively. The mean concentration of Chloride ion, Magnesium ion and calcium ion was 422.09 ± 64.05 mg/L, 61.37 ± 6.56 mg/L, and 200.70 13.23 mg/L, respectively. The mean Chemical Oxygen Demand and Biological Oxygen Demand were also recorded which was 12.67 0.54 mg/L and 7.47 0.67 mg/L, respectively.

The obtained results were also compared to the national and international standards to determine the quality of livestock drinking water. Accordingly, the measured pH was in agreement with World health organization and Ethiopian standards agency standards, which was 6.5 to 8.5. The Temperature, Total hardness and chloride ion concentration was above the standard limit set by World health organization and Ethiopian standards agency. The concentration of Total Dissolved Solid, Mg2+ and Ca2+ was in agreement with World health organization and Ethiopian standards agency standards. The standards for Chemical Oxygen Demand and Biological Oxygen Demand were not available both from World health organization and Ethiopian standards agency.
