The objective of this research was to determine and estimate the quality of ground water for producing village-tap water without pre-treatment in 3 districts Samchuk Nongyasai and Dermbangnangbuat districts Suphanburi province. Villagetap water was collected from 88 boreholes covered 17 sub-districts in June 2014 and January 2015 using standard method and then correctly preserved before analysis process. The result showed that pH conducted in filed using pH meter found in the range 7.0 to 9.2. Total hardness was found in the range of 110 to 590 mg/L as CaCO3. The concentration of Mn Fe Pb was found in the range of 0.08 - 0.88 mg/L nd - 1.88 mg/L and nd - 0.07 mg/L respectively. The concentration of Cd was to be non-detectable for all samples. The result found that total hardness was found higher value than standard quality water according to publish by Ministry of Natural Resources and Environment Thailand. The contamination of Mn and Fe in some samples was higher value than maximum allowable concentration. The problem of Fecontamination can extremely affect to physical properties of quality water. The production of household-water filtration in this work was modified from Bureau of Community Technology Department of Science Service Ministry of Science and Technology. The technology communication of the production household-water filtration was conducted by workshop procedure. The production household-water filtration was conducted step-by-step. All participants can produce the household-water filtration by themselves.
