ABSTRACT
Water is a universal substance that is essential for all known forms of life and due to urbanization and diversified domestic uses, the quality of water gets deteriorated. This study aimed to assess the physicochemical properties of water in Cubay Creek by comparing the temperature, Total Suspended Solids (TSS), and pH values with the Department of Environment and Natural Resources (DENR) water quality standards of Class C Inland Waters The objectives of the study were to determine the temperature, TSS and pH values of the water found in Cubay creek The sampling procedure used in the study was purposive sampling. Sampling areas 1, 2, 3 were near the residential areas along Cubay creek, beside Balabago road, near the agricultural areas along Cubay creek respectively. Three samples were taken from each area and each was tested for and pH. The samples were then brought to the Philippine Science High School Western Visayas Laboratory for the computation of TSS values. The temperature values for areas 1, 2, 3 were 34°C, 31°C, 31°C which all passed the DENR standard which was ±3°C from the initial source of water The TSS values for areas 1, 2, and 3 were 91 67 mg/ml, 11 11 mg/ml., 25 02 mg/ml. respectively. Only area 1 did not pass the DENR standard for TSS which was 0 mg/ml. to 90 mg/mL. The pH values for areas 1, 2, 3 were 8 50, 837, 8 56 respectively All the pH values passed the DENR standard for pH which was 6.50 to 9.00. For better analysis, It is recommend future researchers to include biological which may affect the physicochemical factors of water in Cubay creek. Also, it is recommend using a digital thermometer and include and increase periodical monitoring for greater accuracy.
