Monitoring and Baseline Profile Confluence of Kulaman and Tinanan Rivers in Arakan Valley Philippines
Journal Title: Scholars Academic Journal of Biosciences - Year 2014, Vol 2, Issue 2
Abstract
The study aimed to determine a more intensive 5-month monitoring of Kulaman River, Tinanan River and determine the baseline profile of approximately 1500-m downstream of the confluence of both Kulaman and Tinanan Rivers. Samples were collected from the three sampling stations simultaneously and brought to Ateneo de Davao University Chemistry laboratory for analysis. 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). Using one-way ANOVA, it was found out that pH, DO, BOD, TSS, TDS and TS levels show no significant difference among the three sampling stations. It also shows that in temperature level, station 3 shows significant difference on stations 1 and 2 since sampling was done one sampling station after the other. Thus, time of sampling and distance are considered for the high temperature level of station 3. Lower temperature levels are attributed to the weather condition of the sampling area as the stream was shaded and no disturbance has been noticed before and during sampling. Using t-test, the researcher’s data obtained from sampling stations 1 & 2 differ significantly with respect to parameters such as temperature (station 1), and DO and TDS (station 2). Other parameters such as pH (station 1 & 2), BOD (station 2), TSS (stations 1 & 2), TDS (station 1), and TS (stations 1 & 2) shows no significant difference. Based on the results, Station 3 may be classified according to DENR Administrative Order No. 34 as Class A Category.
