Monitoring Plan
The regional water quality monitoring practice in Taiwan started in 1976. Originally, Taiwan’s Provincial Water Pollution Control Institute performed water sampling in rivers and started its first groundwater monitoring. After the provincial government was reinvented, the work was transferred from the original Third District Center of the Department of Provincial Environmental Protection to the Department of Environmental Monitoring & Information Management (EMIM) under the E.P.A. in September, 2001. Since 2002, the environmental water monitoring routine of the river, sea, reservoirs and groundwater was commissioned to qualified testing with the “Environmental water quality of north, central and southern district monitoring plan”. This plan divides Taiwan to three districts known as north, center, and south. (Hereinafter shortened as three districts). The plan is executed within the budget of the Department of Water Quality Protection and submitted to the Executive council for sanction under both the “Taiwan river and ocean management program(2002 ~ 2004) “ and “River and ocean water quality maintenance and improvement plan (the 1st ~ 2nd stage)(2005 ~ 2011)“.The E.P.A manages to implement the water monitoring routine in Taiwan, Penghu, Kinmen and Matsu for about 6,000 stations per year producing a total of 100,000 water monitoring data. The data was released regularly on the “National Environmental Quality Monitoring Information Website" after careful quality assurance and quality control. Annual reports are compiled and posted to serve for general inquiries. The EPA continues to establish long-term water quality variations and use them as the reference for decisions concerning pollution prevention. Since 2005, The total number of people who browsed the website reached 117,000 views. The EPA also conducts beach water monitoring during summer time. The outcomes are released by issuing statements to remind the public of water safety.The E.P.A also started the water monitoring data exchange operation with local environmental protection agencies, water companies, Water Resources Agency, and Council of Agriculture in 2008.
The former Taiwan Provincial Government Water Pollution Control Institute first conducted the routine work of river water monitoring in 1976. In 2002, the entire work of water monitoring was transferred to the Department of Environmental Monitoring & Information Management, EPA. Now a total number of 296 stations are under regular monitoring.
E.P.A started routine water monitoring for twenty major reservoirs in Taiwan since 1993. The monitoring of 3 items, Phosphate, Chlorophyll-a and transparence that are used to calculate Carlson Trophic State Index (CTSI), which indicate the degree of Eutrophication. In 2002, the operations of reservoir water monitoring extended to include not only the Taiwan mainland but also off-shore islands, which include Penghu County, Kinmen County and Lienchiang County. The monitoring sites and measurement items year after year adjustments, additions and deletions.
The E.P.A started Taiwan regional well groundwater monitoring in 2002. Currently, a total number of 458 groundwater wells are under routine water monitoring. The monitoring sites and measurement items year after year adjustments, additions and deletions.
Sea Area
The water monitoring of sea area in Taiwan started in 2002. The coastal waters are divided into 20 regions and 105 sampling points. The current monitoring frequency is once every season.
In order to let people understand the beach water quality and consider it when participating in water activities the E.P.A conducted water monitoring in the swimming season from June to September every year since 1999. Ten beaches were selected for water monitoring from 2002 to 2008. The number increased to 13 to include Penghu, Kinmen and Matsu in 2009. After a joint meeting with the Tourism Bureau, Scenic Area Administrations and regional governments on Feb. 11 2010, a decision was made to extend the operations to those that attract more swimmers, and delete Da-an and Cinding Beach, that do not provide operation and management. A final list of 23 beaches was determined in 2010.There were 20 beaches in 2011 and 14 beaches in 2012. The monitoring sites and measurement items year after year adjustments, additions and deletions.According to the monitoring results, the EPA would regularly release this information through media and the Internet for public reference.
