The Chemical Analysis of the Variation In the Variousparameters of Underground Boring Water of a Source As Non-Filtered Manipalboring Water and Filtered Manipal Boring Water. The Samples of the Drinking Water In Pokhara Sub-Metropolitan City Werecarried Out. the Characters Selected For the Findings Were Appearance,Turbidity, Colour, Temperature, Ph, Electrical Conductance, Total Alkalinity,Total Hardness, Calcium Hardness, Magnesium Hardness, Total Iron, Chloride,Ammonia, Arsenic, E. Histolytica, Giardia, E.Coli Which Are the Major Drinking Waterparameters. the Chemical Tests Were Done By Photo Colorimeter, Ph Meter,Cmparator, Arsenic Kit Apparatus, the Conductivity Meter (Electronics) – Ec,Different Titrations and Estimation Processes. the Biological Tests Formicrobes Were Copleted By the Pathological Microscope Lbm - 100 D. Thevariation Was Compared With the Permissible Limit. the Water Filter Used In Theresearch Was the General Catadyn Ceramic Filter With Porosity of 0.2 Micrometerand the Result Was Displayed.
