Abstract—Protecting our natural resources is one of the
important thrusts of every organization. In this study, the
waters of Iloilo Batiano River, Philippines is explored. This
study was conducted because there is a dearth of information on
the water physico-chemical characteristics of the river. Since
this is an initial assessment, this study will serve as a baseline
data and the results will serve as a basis for future reference for
conservation measures of the river. The present study aimed to
determine the selected water physico-chemical characteristics
of the river such as the electrical conductivity (EC),
temperature, pH, and calcium content; assess if these
parameters exceed the limit set by the DENR Administrative
Order No. 20F16-08 of the Republic of the Philippines and other
available literatures; and to determine if there was no
significant difference in the water physico-chemical
characteristics among the six sampling stations. Results
revealed that EC and calcium content of the river exceed their
limits except for temperature and pH levels. Furthermore, EC
and temperature were statistically different among the six
sampling stations except for pH values. This study concludes
that the river is saline due to the mixing of saltwater and surface
water as the river is near to the sea and has high calcium
content that can threaten the life of freshwater aquatic
Index Terms—Electrical conductivity (EC), temperature, pH, calcium content, Iloilo.
