EVALUATING THE PHYSICOCHEMICAL AND BACTERIOLOGICAL CHARACTERISTICS OF ALIGODON RIVER AS SOURCE OF POTABLE WATER FOR NEW CLAVERIA WATER SYSTEM

To champion the need of providing quality water to the community, a study on characteristics of the water source is important and of primary consideration.This study aims to determine the physicochemical and bacteriological features of Aligodon River, a drinking water source of new Claveria water system, regarding temperature, turbidity, total dissolved solids (TDS), dissolved oxygen (DO), pH, phosphates, nitrates, biochemical oxygen demand (BOD) and coliform level.The result revealed that TDS, DO, pH, BOD all passed the standards of Philippine National Standards for Drinking Water while turbidity and total coliform all failed in any season of the year.Based on the permissible standards set by DAO 34, TDS, DO, and pH all passed the Class AA classification.The coliform level is present in river water but unquantified which necessitates treatment to attain the desired quality of the water free of pathogen.
