| Abstract | This paper investigates the water quality of Mak Khaeng canal in Udon Thani province using the Water Quality Index (WQI) in order to study the water quality assessment. Mak Khaeng canal is the main canal in Mueang Udon Thani district of a municipality. WQI technique was used following the Surface Water Quality Standards of Pollution Control Department, Ministry of Natural Resources and Environment, Thailand (PCD-WQI). The five parameters based on dissolved oxygen (DO), biochemical oxygen demand (BOD), ammonia (NH3), fecal coliform bacteria (FCB), and total coliform bacteria (TCB) were analyzed to calculate WQI of the canal by the different twelve sampling stations. The result showed the water quality in Mak Khaeng canal is poor in the range. This is because of the inadequacy of the existing sewage systems in Udon Thani city area and untreated wastewater discharged from domestic, school, office, university, markets and commercial sources. Therefore, this research study was expected to present valuable information of WQI for Mak Khaeng canal to water quality management by administrators and community participation of local people. |
