Drinking water samples were taken from 18 villages around Zakho district, Kurdistan region, Iraq in annual seasons of 2018 year and chemical analysis of most important water quality parameters were carried out. Water temperature is varied about 13.2 C to 18.7 C, four villages have slight acidic water while other 15 locations are tend to be slight alkaline and highest pH value reaches 8.4, electrical conductivity (μs/cm) is over the permissible values of standard drinking water in two villages and high in 4 location while normal in the rest 13 locations, statistical analysis of dissolved oxygen ranges between 6.73 - 8.40 mg/l, statistical analysis of total hardness revealed that the all villages around Zakho district have hard to intensive hard water over 500 mg/l and gives them a slight bitter taste, calcium hardness gives extremely ranges between 72-392 mg/l, and Mg hardness between 39-250 mg/l, statistical analysis of chloride shows is around 250 mg/l which is typical standard for drinking water, SO4 is low and their means located between 18-58 mg/l and NO3 not exceeded 5 mg/l along year months reflecting their purity from pollution. The content of heavy metals Cd, Cu, Mn, Zn, Fe, Ag, Ni, Cr,Co, are below maximum permissible WHO guidelines and save for drinking while lead is over WHO permissible levels in this rank Mala> Jajoe> Easlam> Bntate> Banee villages and considered a dangerous indicators for drinking water quality in these villages.
