Sediment Quality Test Results Database Established for Enhanced Sediment Management and Monitoring

The EPA has established the Sediment Quality Test Result Database website to make information on sediment quality in Taiwan more accessible to the public. The website provides regularly updated sediment data, which can be searched according to time, location and test item. It also gives brief explanations of current sediment management policies along with the related scientific background.

Since sediment management was covered by the Soil and Groundwater Pollution Remediation Act in 2014, the EPA has been assisting industry competent authorities to conduct sediment quality testing in all of the water bodies within their jurisdictions, including rivers, irrigation canals, lakes and reservoirs. By 2019, a total of 473 water bodies have been tested for sediment quality, with the test results reported to the EPA and published online. Results showing higher pollutant concentrations in water body sediments would prompt the EPA to investigate the potential causes. For example, in case of agricultural land pollution, the EPA could analyze water quality and pollutant concentration changes through time and space near the polluted site to find the potential pollution sources.

In the future, the EPA will continue expanding the sediment quality database, closely monitor long-term sediment quality trends in Taiwan, investigate causes of high pollutant concentrations and review the sediment quality management system so as to ensure better quality of life for all.
