INVESTIGATION OF PHYSICOCHEMICAL PARAMETERS TO EVALUATE TAP WATER QUALITY IN CASE OF ASEBOT TOWN, OROMIA REGIONAL STATE OF ETHIOPIA

Abstract

Physicochemical Parameters; it pertains both physical and chemical properties, changes, and reaction. The present study conducted to investigate physicochemical parameters of Asebot town tap water quality using argentometric method, titration method, Ratio turbidimeters and inductive coupled plasma-optical emission spectroscopy method for metal analysis. For all analyses, the whole 3 representative samples were randomly selected from different areas of the town. The results were analyzed and interpreted using Microsoft excel spread sheet. The results obtained show that Total hardness, EC, Ca (hardness), Total alkalinity, iron and chromium metal were above the WHO permissible value. All the remaining physicochemical parameters and heavy metal were safe and within the range of acceptable for drinking water quality. The results for Total hardness, EC, Ca (hardness), Total alkalinity, total suspended solid, iron and chromium metal were found between the ranges387.3-430mg/l, 799-805μs/cm, 98.93-101.33mg/l 357.33-373.33mg/l, 102.2-11omg/l, 0.737-0.769mg/l and 0.494-1.247mg/l. By contrast, all parameters were found within the range of WHO recommended values for drinking water quality. Further study was required to draw ultimate conclusion on physicochemical parameters, moreover any concerned body should to check the presence of the rest toxic heavy metal that causes health problems on human’s human being
