With the research objectives as to study the mountain tap water using community of Besoo Village, Bannangsta Sub-district, Bannangsta district. Yala province, concerning to their lead use, the physicochemical quality monitoring of mountain tap water, the seasonal changes in mountain tap water quality the relationship between mountain tap water quality and its physicochemical characteristics, the approaches in managing mountain tap water system, water samples from 1S sampling sites in total were thus collected using method of one-sample-for one-treatment process. All samples were then subjected to analysis of physical characteristics including temperature, turbidity, suspended sediment, total solids and conductivity, and of chemical properties including hardness, pH and chloride content. Samplings were monthly conducted during April 2013 - December 2013, average standard deviation, lest, F test and the Pearson Correlation Coefficient were statistics used in the analysis. Results showed that source of mountain tap water was the forest area, and that of storage well site was used as residential and agricultural purposes. The mountain tap water supplying area covered the residential area. mountain tap water physical characteristics as for those of temperature, turbidity, suspended sediment, total of dissolved solids and conductivity in averages were 26.95°C, 2.47 NTU, 34.96 mg/L, 80.89 mg/L and 125.75 µs/cm, respectively. Mountain tap water chemical quality as for those of the hardness, pH and chloride in averages were 288.18 mg/L, 7.51, and 0.88 mg/L, respectively. Physicochemical quality of mountain tap water in each of sampling sites was different resulting in difference in mountain tap water physicochemical quality. It was further found that turbidity correlated with suspended sediment, conductivity and hardness (p value <0.05) as well as chloride content (p-value <0.01). No correlation was observed with temperature and total of soluble solids. Conductivity showed correlation with the hardness, and soluble solid content correlated with pH (p-value <0.01). It was also observed that mountain tap water supply system was damaged with no fix at some points, and as a consequence, water was highly turbid with mixing of grass clippings, leaves, debris, and sediment during heavy rain.
