Water quality and physical assessment of sungkilaw waterfalls in Zamboanga Norte, Philippines | JBES 2021
Zamboanga del Norte is often considered enigmatic as it has several secret mysteries waiting to be found. Sungkilaw Falls in Zamboanga Norte, Philippines is now listed as a tourist destination as it has proved to be one of Zamboanga Peninsula’s most famous tourist destinations. This study considered three streams using a single sampling technique to assess the fall's physical features and water quality initially. Studied water quality parameters were pH, temperature, biochemical oxygen demand (BOD), turbidity, total dissolved solids (TDS) using pre-calibrated portable meters. Total and fecal coliforms were also determined using the Multiple Tube Fermentation Technique to find out the presence of a member of the coliform group in groundwater and surface water. Overall, Sungkilaw falls water quality parameters are within the normal limit of the DENR standard showing no potential pollution. The presence of coliforms was detected in the bacteriological analysis of the water samples in all sampling stations. These results are possible because of the wastes that leach from industrial, animal, and domestic sewage in the streams. Present findings are preliminary and further analyses and monitoring may be essential.
