The seashore marine water quality of the area northern Zheng-yen River basin was investigated, investigation area ranged from the north side of Ba-Zhang River estuary to the south side of Wang-Zi-Liao Sandbank in Tainan County. In comparison with Environmental Protection Agency’s marine water quality standards (Class A), the 3 monitoring results indicate that the water quality only T-P is out the standards, others is within the standards. The 3 monitoring results show that 43% of the water index concentrations are outstandards. In addition, over the years the concentrations of the total phosphorus are in the decline. In comparison with international water quality standards (NOAA), the results show that the majority of heavy mental concentrations are lower than ERL. All the concentration fluctuations of Copper is lower than ERL. The levels should not cause harm to eco-system. The Nickel level has 40% exceeded ERL standard, but is lower than ERM . Nickel concentration detected here shows 30.6 mg/kg, in comparison with the detected Nickel concentrations from other regions, such as Qi-Gu sediment (45 mg/kg), Dan-shui sediment (55 mg/kg), Koahsiung harbor sediment (59 mg/kg), Jia-yi sediment (32 mg/kg), our results indicated better marine water quality. In comparison with Environmental Protection Agency’s marine water quality standards (Class A), our 9 monitoring results of water quality in the natural habitats of Black-faced Spoonbill indicate that the concentrations of N-NH3, SS have improved. The BOD levels of this region mostly surpass marine water quality standards (Class A), it might be due to the overly populated fishery industries. Marine pollution incidents did not occur this year. For assisting Tainan County marine pollution prevention, our team assisted in the checking of ports and the ships, 725 cases were completed. Only around 34% of the cases turned out to be some pollution events, they are random floating oil and trash problems. In addition, we helped to organize marine pollution prevention info. sessions, which included organizing activities and printing pamphlets.
