Water quality was monitored in Khlong U-Taphao, Amphoe Hat Yai, Changwat Songkhla. The study area was divided into 10 stations and water specimens collected during January to November 1997. The ranged of temperature was 26.0-31.5oC, pH 7.8-9.3, biochemical oxygen demand 0.09-6.8 mg/l, total phosphorus 0.002-0.40 mg/l, total kjeldahl nitrogen 0.11-3.02 mg/l , oil & grease 0.1-12.9 mg/l, total suspended solids 5.0-293.0 mg/l. Khlong U-Taphao has been impacted and polluted from domestic wastewater from Hat Yai Municipality, villages and industry. The water quality in this area is paticularly polluted in the summer season.
In order to have successful water quality management, emphasis should be placed on the controlling of the quality and quantity of waste before discharge into Khlong U-Taphao, removing un-desired aquatic weeds together with disseminating knowledge and information on this subject to people in the area.
