The plan will be the result of the water quality sampling analysis of the water quality monitoring of the Pingtung County River in this year (107) and the "Regional Water Classification and Water Quality Standards" issued by the EPD of the Executive Yuan, the "Risk Classification of River Pollution Rating (RPI)" and the Water Quality Index. Classification table (WQI) for comparison, In order to assess the water quality of the rivers in Pingtung County, the long-term water quality data of the Pingtung County rivers will be gradually established for the competent authorities to grasp the water quality of the Pingtung County rivers and as a reference for the future development of relevant control measures to prevent river pollution and protect the river ecology.
The plan is from January to December 31, and the schedule and actual progress of each work are shown in Table 1. This year's sampling has been completed from January to December of the Republic of China, and 12 sampling inspections have been completed. The comprehensive analysis of the water quality test results is as follows:
(1) Donggang River Basin: The quality of Donggang River Basin is roughly divided into two sections: the upstream station (including Chengde Bridge and Wanyu Bridge) and the downstream station (including Wukui Bridge and Gangdong No. 2 Bridge); in general, the upstream station The water quality is slightly better than the downstream station. The water quality of each station was evaluated according to the RPI classification. The water quality of the stations of Wukui Bridge and Gangdong No. 2 Bridge mostly belonged to moderate pollution level. According to the WQI classification assessment, from January to December of this year, in 12 samplings, the water quality stations of Chengde Bridge and Wanyu Bridge belonged to the middle to the lower reaches of the river. The Wukuiqiao station belongs to the middle to the lower reaches of the river. The No. 2 bridge station belongs to the medium to bad river section. According to the value of WQI, the upstream section is superior to the downstream section.
(2) Linbian River Basin: According to the RPI classification of the Linbian River Basin, in the 12 sampling periods, the serious pollution level of the Xinyi Bridge station has been improved to the level of uncontaminated from last year. The water quality of the Linbian River is mostly moderately polluted. According to the WQI classification assessment, the water quality of Linbian River is divided into the Xinyi and Linbian Bridge stations. The water quality of the Linbian Bridge station is good to the middle and lower reaches of the river. The Xinyi Bridge station has improved the discharge of wastewater from the upstream in recent years. It has shown that environmental protection units have strengthened the inspection and control of animal husbandry pollution sources. The results have been quite good except for the middle reaches of the rivers in August, September, October and December, and the rest of the months have reached a good river section.
(3) Wannianxi River Basin: Wannianxi is classified according to RPI. From January to December this year, except for Guangdong Bridge in March, Chonglan Old and Xinzheng Confluence in May, and Guangdong Bridge and Chonglan Old and Xinzhen Confluence in June. In addition to serious pollution, the rest are mild to moderately polluted. According to the WQI classification assessment, the Guangdong Bridge Station has 2 bad water bodies, 8 subordinated lower water bodies and 2 medium water bodies in 12 samplings, and 7 times in the Fuxingqiao station are in the middle and lower water bodies and 5 times. In the medium water body, there are 3 bad water bodies, 5 middle and lower water bodies, 3 medium water bodies and 1 good water body in the intersection of Chonglan and Shenzhen.
(4) Other rivers: According to the RPI classification, the water quality of each station is evaluated according to the RPI classification. The county and rivers (except Donggangxi) are mostly moderately polluted except the Linhai Bridge. Most of the others are unaffected. Pollution to a slight degree of pollution. Except for the slight pollution of the Lushan Bridge, Longyan Lake, Linhai Bridge and Manzhouqiao Station in March, the remaining stations belonged to uncontaminated rivers. In June, except for the port bridges, moderate pollution, Lushan Bridge and The Linhai Bridge is slightly polluted, and the rest of the stations are uncontaminated rivers. In September, except for the light pollution of Fenggang Bridge, Longjing Lake is moderately polluted, and the rest of the stations are uncontaminated. In December, except for Fenggang Bridge, Longyan Lake and Linhai Bridge, the other stations were all unpolluted rivers. According to (WQI) classification, except for the imitation of the mountain bridge, Linhai Bridge and Manzhou Bridge in March, the Manchu Bridge is a medium river section in June, and the Zhonghe River and Linhai Bridge are medium-sized river sections in September. The rest are good to good river sections, and in December they are all good river sections.
