Competent authorities at all levels shall officially publish waters environmental monitoring data from the previous year prior to April 15 of each year .
Measures for Waters Environmental Article 1 These Measures are established pursuant to Article 9, Paragraph 3 of the Marine Pollution Control Act (hereinafter referred to as this Act.
Article 2

Waters environmental monitoring stations shall be installed in the following locations:

  • primary and secondary estuaries;
  • major inflow spots of pollution sources;
  • harbors or lagoons;
  • areas designated in Article 15, Paragraph 1 of this Act;
  • locations with general marine water quality; and
  • other locations designated by the central authority.
Article 3

Waters environmental monitoring items shall be in accordance with the following classification of pollution sources or characteristics of waters:
A. Required monitoring items:

  • hydrology of waters: flow speed, flow direction and water temperature;
  • water quality of waters: salinity, hydrogen ion concentration index, amount of dissolved oxygen and suspended solids; and
  • other items designated by the central authority.
B. Optional monitoring items:
  • hydrology of waters: wave height, wave direction and wave period;
  • water quality of waters: light intensity in water, chlorophyll a, coliform, heavy metals, nutrients (nitrate, nitrite, ammonia nitrogen, phosphate and silicate); and
  • organisms of waters: plankton (animal and plant plankton) and benthos.
Article 4 Methods for the sampling of waters environmental water quality and waters environmental organisms, sample preservation and testing and analysis shall be in accordance with methods officially announced by the central authority.
Article 5 Methods for the sampling of waters environmental water quality and waters environmental organisms, sample preservation and testing and analysis shall be in accordance with methods officially announced by the central authority.
Article 6 These Measures shall take effect on the date of promulgation.
Surface Water Classification and Water Quality Standards Article 3

The classification of terrestrial and marine surface water bodies are intended to specify the nature of application and relevant environmental standards for water bodies on the basis of their characteristics, but not to restrict the uses of water bodies .

Relevant environmental standards for water bodies concerning the protection of the living environment and human health are shown in Table 1 and Table 2 respectively
Article 8

Taiwan coastal waters environment categories range from coasts of the Taiwan Island, the Pescadores Islands, the Orchid Island and the Green Island to extended territorial waters.

Taiwan coastal waters area and the classification of waters are shown in Table 3 according to the best use, assimilative capacity and water quality conditions of waters.
