The study is an intensive 5-month monitoring of Kulaman and Tinanan Rivers to determine the baseline profile at approximately 1,500 meters downstream of their confluence. Samples from the three sampling stations were simultaneously collected then analyzed at the ADDU Chemistry Laboratory. Chemical parameters analyzed were pH temperature, dissolved oxygen (DO), biochemical oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), and total solids (TS). One-way ANOVA analysis showed that pH, DO, BOD, TSS, TDS and TS levels show no significant difference among the three sampling stations. T-test also shows that data obtained from Stations 1 and 2 differ significantly with respect to parameters such as temperature (Station 1), and DO and TDS (Station 2). Based on the results, Station 3 may be classified according to DENR Administrative Order No. 34 as Class A Category.
