In order to ensure the safety of drinking water on outlying islands and understand the current quality of drinking water in Ludao Township and Lanyu Township in Taitung County, three drinking water quality sampling and analysis operations were conducted during the contract period, and the test results over the years were compiled and analyzed. We will explore the causes and improve countermeasures for areas and water quality projects that do not meet drinking water source water quality standards and drinking water quality standards, and develop drinking water safety management. The implementation work content is summarized as follows:
1. Sampling and testing of tap water source water quality
The monitoring locations for this year are Green Island Water Purification Plant (Green Island Wells 1 and 2), Lanyu East Purification Water Plant, Lanyu Hongtou Water Purification Plant, Lanyu Langdao Water Purification Plant, etc., which should be completed this year. 3 water quality sampling inspection operations. This project completed three water quality sampling inspection operations in April, June, August (Green Island) and September (Lanyu) in 2013, and the results were all in compliance with the drinking water source water quality standards.
2. Sampling and testing of reservoir water quality
This year's monitoring location is the Green Island Houqin Reservoir. This project has completed three water quality sampling inspections. The test results were judged by the Carlson Index (CTSI). The water body of the Houqin Reservoir has reached the quality level.
3. Sampling and testing of tap water quality
The monitoring locations for this year are Ludao Water Purification Plant, No. 1-2 Gongguan Village, Ludao Township, next to Zhongliao Bridge in Zhongliao Village, Ludao Township (Fude Tuigong Temple), and No. 194, Nanliao Village, Ludao Township, Ludao Township There are a total of 7 places including the National People’s Congress (Old Hall), Lanyu Township East Purification Water Plant, Lanyu Township Hongtou Water Purification Plant, Lanyu Township Langdao Water Purification Plant, etc. This plan will be held in April, June, and August 2013. In March (Green Island) and September (Lanyu), three water quality sampling inspection operations were completed, and all measured values were in compliance with drinking water quality standards.
4. Sampling and testing of non-tap water quality
This year, monitoring was carried out at two locations: Coconut Oil Elementary School and Lanyu Coconut Oil Community. This project has completed three water quality sampling inspections, and the test results showed that the bacteria removal standards (E. coli group, total bacterial colony count) ) exceeds the standard, the rest of the test items are in line with drinking water quality standards. It is recommended that publicity should be strengthened to maintain environmental sanitation near water intakes to avoid pollution from human activities, and ensure that non-tap water should be boiled or disinfected before drinking. concept.
According to this year’s test results, the pass rate of the first water quality test in Ludao Township was about 30% (only 3 companies passed), and the pass rate of total bacterial colonies was about 50% (5 companies passed the test). The second water quality test in Ludao Township The passing rate of coliform testing was 0% (all failed), and the passing rate of total bacterial colonies was about 30% (only 3 companies were qualified); the passing rate of the first water quality test for coliforms in Lanyu Township was about 20% (four companies were qualified) ), the pass rate for the total bacterial colony count was about 50% (10 companies passed), the pass rate for the second water quality test for coliforms was about 30% (6 companies passed the test), and the pass rate for the total bacterial colony count was 0% (all failed). The water sources used by households or businesses come from mountain springs and groundwater, and most of them do not have disinfection procedures. We should continue to promote "boil and not drink raw" to improve the safety of drinking water for the public. As for nitrate nitrogen, all measurement points meet drinking water quality standards. In addition, regarding chloride salt, some monitoring points using groundwater may have a tendency to become salinized due to long-term use of groundwater, so the chloride salt detection value may be higher than the drinking water quality standard.
