SORIANO, MA. GENEVEVE CABALLERO, College of Arts and Sciences, University of the Philippines Los Banos. April 2006. ASSESSMENT AND MONITORING OF THE WATER QUALITY OF THE MAIN SOURCES OF UPLB DRINKING WATER SYSTEM.

Adviser: Dr. Maxima E. Flavier

Assessment and monitoring of the water quality from five deep wells and four pump houses were conducted from December 2005 to February 2006. Three of the five deep wells (DW 1, DW 5, and DW 6) are not monitored by the UPLB OHSSC. The water quality parameters analyzed were pH, turbidity, temperature, TDS, TSS, total hardness, residual chlorine, nitrate-nitrogen, total lead content and total iron content.

Analyses showed that the mean values obtained for the different parameters were as follows: pH, 6.72; turbidity, 0 NTU; temperature, 32.37°C; TDS, 464.08 mg/L; TSS, 18.35 mg/L; total hardness, 220.97 mg/L CaCO3; residual chlorine, 0.13 mg/L; nitrate-nitrogen, 1.44 mg/L; total lead content, 0.36 mg/L; and total iron content, 1.33 mg/L. Except for residual chlorine and total lead content, all the values for the different parameters tested conformed with the maximum allowable limits set by the Department of Environment and Natural Resources (DENR), Philippine National Standards for Drinking Water (PNSDW) and the World Organization (WHO).

Analysis of Variance was performed on all the parameters except for turbidity, to determine significant variations in the values with regards to sampling site and sampling time. The results show that pH, temperature and TSS vary with sampling time at 5% level while total hardness and residual chlorine vary significantly with sampling site at 5% level. The pH also varies significantly with sampling site at 1% level.

Correlation analysis was done to pH and lead content and to pH and iron content. Results show that pH has a positive, moderate and significant correlation with lead and a positive, weak and significant correlation with iron.
