Abstract:
Monitoring a river’s water quality can help maintain the minimum conditions
necessary to assure the suitability of water for its designated use. A rapid water
characterization was conducted on Talisay River, Balanga City, Bataan. The study
aimed to determine the existing water quality of Talisay River. Limnological and
the physico-chemical characteristics of four pre-determined stations were
measured. Microbial load was also tested. ANOVA and DMRT were used to
determine significant differences among results of numerical parameters done.
Station 1, upstream, was found suitable for Class B waters that can be used for
agriculture and irrigation. With respect to its physico-chemical attributes. Stations
2 and 3, both midstream do mark a relative high level of coliform count and
dissolved solid residues as a result of the different effluents discharged into the
water was still of Class C standard. Station 4, located upstream, was found to
have Class C water well-suited for fishery and aquaculture. The study showed that
Talisay River has a similar condition that of the previous study conducted and had
maintained the former standard set by DENR.
