The healthy aquatic ecosystem is dependent on physico-chemical and biological characteristics (Venkatesharaju, Ravikumar, Somashikar&Prakash, 2010). The quality of water in any ecosystem provides significant information about the available resources for supporting life in that ecosystem. Good quality of water resources depends on a large number of physico-chemical parameters and biological characteristics. Thus, monitoring these parameters is essential to identify the magnitude and the source of any pollution load (Thirupathaiah, Samatha&Sammaiah, 2012). This study was conducted in order to determine the chemical properties of the water of Napolan River located in Brgy. Napolan, Pagadian City, namely; the pH, dissolved oxygen, salinity, total dissolved solids and electrical conductivity); the microbial presence;and to evaluate the awareness of the residents regarding the quality of the water using a self-made questionnaire. The said chemical properties were determined during dry season and wet season. Water samples were brought to Pagadian City Water District (PCWD) for a test on microbial presence.
The results of this study showed that the chemical properties of the water samples from Napolanriversupport the growth or reproduction of Coliform bacteria which is an indication of fecal contamination. Water samples taken during dry season were noted to contain more coliform bacteria than those collected during wet season.
