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 carried out during the contract period, and the test results over the years were compiled and analyzed. For regions and water quality projects that meet drinking water source water quality standards and drinking water quality standards, we will explore the causes and improve countermeasures, and develop drinking water safety management.
1. Sampling and testing of tap water source water quality
This year's monitoring locations include Green Island Water Purification Plant, Lanyu East Purification Water Plant, Lanyu Hongtou Water Purification Plant, and Lanyu Langdao Water Purification Plant. Three water quality sampling inspections should be completed this year. This plan will complete three water quality sampling inspection operations in April, June and September 2022, and the results all meet 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, and three water quality sampling inspections should be completed this year. This plan will complete three water quality sampling inspection operations in April, June and September 2022, and the results all meet the drinking water source water quality standards.
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 Tudigong Temple), and No. 194, Nanliao Village, Ludao Township, Ludao Township There are 7 water purification sites in total, including the National People's Congress (Old Hall), Lanyu Township East Purification Water Plant, Lanyu Township Hongtou Water Purification Plant, and Lanyu Township Langdao Water Purification Plant. Three water quality sampling inspections should be completed this year. This plan will complete three water quality sampling inspection operations in April, June and September 2023. Among them, except for the second water quality sampling phenolics and the E. coli group and total bacterial colony count at the Green Island Water Purification Plant and Zhongliao Village Zhongliao Bridge (Fude Tuigong Temple), the other two water quality testing results All meet drinking water quality standards. In addition, for the aforementioned water quality exceeding the standard, retesting operations were started on August 17 for the parts that exceeded the standard, and the retest results were all in line with the "Drinking Water Quality Standards."
4. Sampling and testing of non-tap water quality
This year's monitoring will be carried out at two locations, including Lanyu's Coconut Oil Elementary School and Lanyu Coconut Oil Community. Three water quality sampling inspections should be completed this year; this plan is to complete three water quality sampling inspections in April, June and September 2022 respectively. The results of the sampling inspection showed that except for bacterial standards (E. coli and total bacterial colonies) exceeding the standards, the other test items were in compliance with drinking water quality standards. It is speculated that it may be related to the fact that non-tap water sources are mostly mountain spring water, which is easily affected by surrounding pollutants, and the water is not disinfected. In the future, publicity should be strengthened to maintain environmental hygiene near water intakes to avoid pollution from human activities, and implement the concept that non-tap water should be boiled or disinfected before drinking.
In addition, regarding the water quality testing of non-tap water users in Lanyu Township, in order to truly understand the water quality conditions of groundwater or mountain spring water in Ludao Township and Lanyu Township, it is planned to select 10 households in Ludao Township using a circular site selection method across the island. , Lanyu Township selected 20 households as long-term monitoring points for non-tap water users. Two water quality sampling and inspection operations should be completed this year; this plan is to complete two water quality sampling and inspection operations for non-tap water users in April and September 2022 respectively. According to this year's test results, the pass rate of the first water quality test for coliforms and total bacterial colonies in Ludao Township was about 30% (three companies each passed), and the pass rate of the second water quality test for coliforms was about 50% (five companies passed the test). ), the pass rate of total bacterial colonies is about 80% (8 companies passed); the first water quality test in Lanyu Township, coliform group pass rate is about 15% (3 companies passed), the pass rate of total bacterial colonies is about 5% (only 1 company Passed), the pass rate of the second water quality test for coliforms was about 45% (9 companies passed), and the pass rate for total bacterial colonies was about 25% (5 companies passed). As for nitrate nitrogen, except for the first test value measured by Hongfa B＆B, which was slightly higher than the drinking water quality standard, the second water quality sampling results all met the drinking water quality standard. Regarding chloride salts, some monitoring points using groundwater may have a tendency to become salinized due to long-term use of groundwater, so the chloride salt detection values are higher than the drinking water quality standards.
5. Handle publicity meetings, briefings and education training related to drinking water on outlying islands
This project has held one outlying island safe drinking water promotion meeting on May 18 and June 23, 2022 respectively at Ludao Elementary School in Ludao Township, Taitung County and Taitung County Lanyu Senior High School. On May 22, June 12, June 19, July 23, August 20 and October 15, 2022, at Zhongliao Fishing Port in Ludao Township, Sugihara Bay in Beinan Township, and Taitung County Environment The Conservation Bureau, Green Island Nanliao Fishing Port, Human Rights Memorial Park and Taitung Forest Park Prairie held 7 briefing sessions to promote the offshore drinking water sharing platform.
In addition, in order to improve the planning staff's skills in water quality sampling and testing, all planning staff are required to participate in educational training on water quality sampling and testing technology or drinking water safety management technology that lasts for more than 4 hours. This project has been launched on April 11, 2022. Submit the "Water Pollution Audit Regulations and Water Quality Sampling and Inspection Technology Education and Training Plan" and complete the process on April 20, 2022.
6. Analysis of drinking water quality in outlying islands and improvement strategies
The prerequisites for safe drinking water are good water sources, complete water purification treatment, sound water transmission and distribution systems and proper water equipment. Therefore, to drink safe drinking water, in addition to relying on tap water professionals to strictly monitor water purification treatment and supervisors In addition to promoting water quality inspection and control, agencies also need to effectively promote the public's full cooperation. This includes jointly maintaining drinking water sources, not arbitrarily pumping groundwater for drinking, preventing secondary pollution of tap water, and doing regular maintenance of drinking water equipment (water dispensers) to ensure drinking water safety.
The tap water source of Ludao Township is mainly used by the No. 1 supplementary well, the No. 2 deep water well in the Ludao water purification plant and the Houqin Reservoir to supply drinking water for people's livelihood in Ludao Township. The tap water penetration rate is about 69.94%. Lanyu's tap water system is supplied by Dongqing, Hongtou and Langdao water purification plants. They all use surface water bodies as water sources. After slow filtration and disinfection, they are supplied to Dongqing Village, Hongtou Village and Langdao Village respectively. Their water supply volumes are respectively 200, 500 and 170 CMD, the actual water supply population is about 1,833 people, and the tap water penetration rate is about 41.65%. Currently, only Coconut Oil Village does not have tap water available.
According to the drinking water quality test results over the years, Green Island has a tendency to have high total trihalomethanes in tap water due to reservoir optimization and high total organic carbon in raw water. However, because the tap water source has been changed to the No. 1 replenishment well, The No. 2 deep water well and the Houqin Reservoir in the Green Island Water Purification Plant are used in conjunction with each other, and the quality of tap water supply has improved. From the testing data in the past three years and this year, it can be seen that this phenomenon does not exist. In addition, the pass rate at each point in the past three years is 100%, which shows that the quality of water supply in outlying islands is gradually stabilizing. The main potential problem with Orchid Island's drinking water is the poor water quality rate of non-tap water and simple tap water sources in the Coconut Oil community. The main problem is that E. coli and total bacterial count are not up to standard. This is due to exposure to open spaces and lack of disinfection. Frequently Asked Questions to Deal with. Therefore, it is recommended to strengthen publicity on water safety to the public, and the public is advised not to drink it raw, but to boil it before drinking.
7. On-site physical examination guidance for water tanks, water towers and drinking water facilities in public and private places on outlying islands
This plan invites "Professor Chen Guanzhong" from the Department of Environmental Engineering and Science of Pingtung University of Science and Technology and "Technician Huang Junren", the person in charge of Asia Pacific Environmental Technology Co., Ltd., from May 16 to May 21, 2022, to target 30 institutions or hotel operators Carry out on-site physical examination and guidance for drinking water equipment maintenance (water tower or reservoir cleaning and maintenance, drinking water equipment maintenance, etc.), conduct on-site inspections of their reservoirs, water towers, and drinking fountains, and understand their "cleaning and maintenance" "Situation", "Registration of Cleaning and Maintenance Records", "Water Quality Testing", etc. to understand the current situation, evaluate the current situation and provide suggestions for areas for improvement to assist hotel and B＆B operators in maintaining the safety of their drinking water, and Follow up on its maintenance or improvements.
8. Water quality inspection of fixed equipment for continuous drinking water supply for hotels and resorts in Ludao Township
This project has completed four water quality tests for E. coli on fixed equipment for continuous drinking water supply on outlying islands in March, June, August and October 2022, totaling 122 times. This year's inspection results show that all B&Bs meet drinking water quality standards and can be safely consumed by the public or tourists.
9. Design and produce promotional materials
This plan has submitted a project proposal for promotional materials on July 21, 2022, and completed the delivery of 1,000 promotional materials on August 1, 2022; in addition, in addition to the need to produce 1,000 promotional materials according to the contract In addition to the number of copies, the project promised to provide 1,000 copies of promotional materials for the promotion of the Ludao Township drinking water sharing platform during the manufacturer's work scope definition meeting, and the purchase has also been completed.
10. Database update
As of December, all relevant sampling and testing data for this project have been archived and logged in the "Drinking Water Management System" and "Environmental Protection Audit and Punishment Control System (EEMS System)" of the Environmental Protection Department of the Executive Yuan. It also assists in completing tap water quality audit control. 584 cases have been implemented, 69 cases of tap water source water quality inspection and control, 26 cases of drinking water quality treatment chemical control, 71 cases of simple tap water and unmanaged non-tap water for drinking, water quality inspection and control, simple tap water and community-owned public water supply equipment water source water quality 8 cases were audited and controlled, 253 cases were inspected and controlled for drinking water equipment maintenance and management and water quality, 12 cases were inspected and controlled for the quality of packaging and contained drinking water sources, and 5 cases were inspected and controlled for pollution behavior in drinking water protection zones, for a total of 1,028 cases.
