Abstract: The objective of the study is to measure the defined water qualities of the well waters from Taif regions, KSA. Quality analysis of is needed to provide necessary data regarding the sources of pollution and pointers for health protection. Physiochemical and microbiological qualities of the samples from 11 distinguished wells were fastidiously evaluated. The observed pH (7.5 to 8.2)  of the collected samples are lies underneath counseled standards. Distribution of the 15 chemical elements in the samples were determined. Among all the principle elements of soil ‘cations' are higher in  the T2 samples like  sodium(Na) (531 mg /l), calcium(Ca) (252 mg/l) and lead(Pb) (0.11 mg/l). Almost all the samples are contaminated with potassium (K) and phosphorus (P). The observed concentration are ranged between (0.259 to 9.23 mg/l) and (0.062 to 0.43 mg/l) respectively. The highest concentration of potassium was observed in T3 and T17.  Samples from the wells which is nearby agriculture lands are highly contaminated than the other wells. The pathogenic indicators were detected in many samples in that  (T1,T17,T23,) as of fecal contamination. Continuous assessment of water quality on the routine basis is needed to maintain the well water quality as well as to eliminate health issues.
