Physicochemical Analysis of Palico River: Input for Biodiversity Conservation

Abstract

INTRODUCTION

Water resources play a very important role in all biotic organisms. Republic Act 9275 or the Philippine Clean Water Act of 2004 was enacted that centers on protection or preservation of water bodies like rivers. However, there are still a number of factors that contribute today adding to its destruction. In this study, the researcher believes that the river is one important water resource and must undergo physicochemical assessment. It must be done to ensure its water quality condition and to advocate awareness and environmental concern through biodiversity conservation.

METHODS

The study used experimental research through sampling method of water samples. Water samples were collected (Palico River, Palico, Nasugbu, Batangas) and brought to a licensed testing laboratory. Biological Oxygen Demand (BOD) and Fecal Coliform count were tested. Also, pH, salinity, and turbidity were assessed through the help of Nasugbu Water District. A number of people and residents living near/ around the river were interviewed to enhance the data. With this, experimental approach was used in data collection in this qualitative-quantitative research that gives the ability to collect accurate data on and provide a clear picture of the phenomenon under study.

RESULTS

As regards to the descriptions of the river it was determined to be great in terms of agricultural and recreational activities. Many residents in the area are planting corns, kangkong, sili, papaya, gabi plants, banana trees, and sugar canes and houses were built nearthe river. Palico river physicochemical assessment indicated the condition of the river. On the average, pH, BOD, salinity measurement, and fecal coliform count were determined to have positive results. The BOD and fecal coliform count three years ago did not affect the result on the assessment of the river. Thus, conservation through the integration plan had identified the areas of concern to improve the biodiversity.

DISCUSSIONS

The results show that Palico community may be able to use the river watershed for planting other crops or plants that can be a source of income. Additionally, a biodiversity conservation plan for the community was prepared by the researcher which can be adapted and implemented to address the identified areas of concern. Implementation of this biodiversity conservation plan may help the community to maintain a clean and green water environment. Also, future researchers may consider exploring same water parameters in undertaking studies related to this present study.
