Ylang-ylang River, Water quality test, physicochemical parameters, microbiological content


Ylang-ylang River is in Cavite, Philippines, wherein it is subjected to a water quality test in 3 specific locations, namely, Aminta, Salipit, and Prinsa stations. The quality test includes the river’s physicochemical parameters and microbiological content, which is then compared to the updated Department of Environment and Natural Resources (DENR) Administrative Order No. 2021-19’s Water Quality Guidelines. The methods utilized in this study include a laboratory analysis for the physicochemical content and an MPN test for the microbiological content. It is shown that the Salipit River had abundant Total Suspended Solids, Biochemical Oxygen Demand, Color, Phosphate and Copper, which also exceeds the regulatory limit of DENR’s guidelines and standards for water quality. Furthermore, Aminta and Prinsa rivers also exhibited a large amount of copper and phosphate in its waters, which didn’t meet the standards of DENR. On the other hand, the microbiological profiles of the rivers are considered safe according to the MPN test and DENR standards. s is considered safe according to the MPN test and DENR standards.
