Abstract

The river pollution or contamination is caused by several factor such as growth in the industrial development, urbanization transformation and increase in the population density. River pollution may negatively effect human health, well-being and the environmental condition. Juru River basin is among the contaminated rivers in Malaysia which located in Pulau Pinang, Malaysia. Even though many green activities have been implemented but the result still the same. In this paper, Principal Component Analysis is employed for pinpointing the most influential parameter in Juru River Basin. It is important to know what the root cause of the water quality is. There are 20 parameters in measuring water quality, therefore, PCA is useful statistical techniques in handling a larger number of parameter. Bimonthly data is gathered from 2008 to 2017 Department of Environment (DOE). From the analysis, there are eight influential parameter that have to control which are salinity, conductivity, dissolved solids, calcium, zinc, pH, arsenic and ammonia nitrogen. We expect to help the DOE to put the focus on these eight parameters instead of monitoring 20 parameters. Once we control all of the identified influential parameters, the rest will be in-control.
