Abstract

Protecting our natural resources is one of theimportant thrusts of every organization. In this study, thewaters of Iloilo Batiano River, Philippines is explored. Thisstudy was conducted because there is a dearth of information onthe water physico-chemical characteristics of the river. Sincethis is an initial assessment, this study will serve as a baselinedata and the results will serve as a basis for future reference forconservation measures of the river. The present study aimed todetermine the selected water physico-chemical characteristicsof the river such as the electrical conductivity (EC),temperature, pH, and calcium content; assess if theseparameters exceed the limit set by the DENR AdministrativeOrder No. 20F16-08 of the Republic of the Philippines and otheravailable literatures; and to determine if there was nosignificant difference in the water physico-chemicalcharacteristics among the six sampling stations. Resultsrevealed that EC and calcium content of the river exceed theirlimits except for temperature and pH levels. Furthermore, ECand temperature were statistically different among the sixsampling stations except for pH values. This study concludesthat the river is saline due to the mixing of saltwater and surfacewater as the river is near to the sea and has high calciumcontent that can threaten the life of freshwater aquaticorganisms.
