Keywords:Surface water quality, Water Quality Index (WQI), Phra Nakhon Si Ayutthaya
The surface water quality around the Rojana Industrial Park, Uthai District and Bang Pa In District, Phra Nakhon Si Ayutthaya Province from 4 canals as Nongmaisung Canal, Kum Canal or Khok Mayom Canal, Chong Sadao Canal and Pho Canal. The samples were collected from 10 sites of surface water in 3 month: April, August and December. The water qualities included physical chemical and biological analysis such as pH, temperature, DO, BOD, ammonia – nitrogen, nitrate- nitrogen, Mn, Coliform Bacteria and Fecal Coliform. The result found that the water quality index is in the range 45 - 71, which SW8 was rated as good and the other points were bad. The water quality in the canals was based on the standard could be classified as class 2-4. This water quality information is useful for surveillance and monitoring, as well as its use in the management of water resources.
