In response to increasing concerns and conscious about environmental protection issues, Environmental Protection Administration of Republic of China (EPA/ROC) has formulated and issued Soil and Groundwater Pollution Remediation Act and Ocean Pollution Control Act. EPA/ROC also amended several regulations including Water Pollution Control Act, Air Pollution Control Act, Noise Control Act, Drinking Water Management Act, and Waste Disposal Act as well as Environmental Standards. To collaborate with all the amendment, the National Institute of Environmental Analysis (NIEA) of EPA/ROC decided to review and revise water quality related regulations, methods, and guidelines. Additionally, the NIEA are in need of a guideline for water quality examination that not only complies with current regulations but also infers from environmental guidelines of other major countries. The Water Quality Examination Guideline formulated in this project consists of (1) introduction - general description to the content of each chapter; (2) applicability – the water bodies to which the guideline applies; (3) quality management – assessment of quality assurance, quality control, data quality, measurement uncertainty, method detection limit, data quality objective, and measurement accuracy; (4) examination management – principles of analytical method verification, interference, sample pretreatment, equipment, reagent, standards grade, instrument maintenance, sample preservation, result presentation, safety, and waste reduction, and (5) appendices –glossary and basic statistical analyses related to water quality examination.
