''See'' Environmental monitoring, Freshwater environmental quality parameters and Bioindicator. * wastewater--characteristics of polluted water (domestic sewage or industrial waste) before treatment or after treatment. ''See'' Environmental chemistry and Wastewater quality indicators. * "raw water" quality--characteristics of a water source prior to treatment for domestic consumption (drinking water). ''See'' Bacteriological water analysis and specific tests such as turbidity and hard water. * "finished" water quality--water treated at a municipal water purification plant. ''See'' Bacteriological water analysis and . * suitability of water for industrial uses such as laboratory, manufacturing or equipment cooling. ''See'' purified water. ==Government regulation== Government regulations related to water testing and water quality for some major countries is given below. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Water testing」の詳細全文を読む スポンサード リンク
