Variable factors affecting the water quality: A case study of water quality variables in the middle part of the Tha Chin River, Thailand
Keywords:
Water quality, Water quality index, Middle part of Tha Chin River, HygienicAbstract
This research aimed to analyze the water quality index (WQI) data and variable factors affecting water quality to improve water quality in the middle part of Tha Chin River. The water quality measurement was obtained from 8 stations among the river during 2011-2020, with samples taken quarterly.The important parameters included Dissolved Oxygen (DO), Biochemical oxygen demand (BOD), Ammonia Nitrogen (NH3-N), Total Coliform Bacteria (TCB), Fecal Coliform Bacteria (FCB), the average rainfall, and the flow rate of Tha Chin River during 2019 to 2023.
The results found the overall WQI of the central Tha Chin River remained unchangedover the past decade, which mostly classified as poor quality. Multiple regression analysis and WQI values revealed that increased levels of BOD, NH3-N, and TCB were associated with decreased WQI values, while higher DO levels correlated with increased WQI. In addition, during the dry season, average rainfall in May and December caused a direct variation in WQI, while rainfall in October during the rainy season also had a direct effect. Conversely, rainfall in July resulted in an inverse effect on WQI. The flow rate of the Tha Chin River in June, July, and February positively influenced water quality, with WQI values changing directly in response. In contrast, the flow rate in November had an inverse effect on WQI. The predictive equation demonstrated an accuracy of 100.0% in forecasting results at a statistical significance level of 0.05. Continuous monitoring of all 5 parameters is essential
to prevent water pollution issues in the central Tha Chin River. 5 parameters should be monitored to prevent water pollution problems in the central Tha Chin River as much as possible.
