Abstract: 

Thirty samples were collected from differentfour residential communities of Zabied City in Yemen to evaluate householdwater for drinking use. TDS and EC content ranged from (355 to 375) mg/L and(883 to 933) Scm-1 respectively. Na is the most dominant cationin household drinking water and represents 56.24% of totalcations, whereas HCO3- is the most dominant anion andrepresents 58.80 % of the anions in the samples. The order of abundance Ions were: Na > Ca 2, Mg 2 and K > Cl-> NO3- and HCO3-> SO4-2 > Cl- > NO3-. The total hardness (TH) as (CaCO3-) in this study rangedfrom 220 to 270 (mg/l). All of the studied samples belong to thevery hard water type. The Household Drinking Water Quality Index (WQI) of Zabied City in four areas indicates to good water quality index in four areaswhich ranged from 56.85 to 58.29. The contents of heavy metals in all samplesfall within the World Health Organization (WHO) guideline limits and Yemenistandards with a range of (0.001-0.005) for Cu, (0.001-0.006) for Zn, (0.001-0.005)for Cd, (0.001- 0.003) for Cr, (0.004-0.009) for Fe, (0.001- 0.006) for Mn,(0.001-0.005) for Co, (0.001- 0.005) for Ni, (0.001-0.005) for Al. The firstcomponent (PC1) accounts for 4.87 and is controlled by HCO-3, TDS, and Na. PC2accounts account for 2.82 and is controlled by Ni, Fe, and F, in addition toPC3 which accounts for 2.569 and is controlled by TH and Mg.
