Though the environmental education of the water quality has been done from the old days, there is no index of the precise water pollution. The obstacle of the environmental education is a problem like a technological argument.In this research, to get an accurate and simple water index, water chemical analysis of the closing water area such as irrigation pond was done, and multivariate analysis and neural network analysis were done. Environment educational program was developed, and then education practice and teacher training were done.As a basic research, 25 pond was chemical, physical, biological surveyed inside Osaka Prefecture, and the result was analyzed the self-organization map and the fuzzy clustering. Artificial closing pond was made, and water purification by the emerging plant such as a lotus was tested and analyzed by "fuzzy c-means method". From two results of an experiment, nitrogen and phosphorus were excellent water evaluation index, and emerged plants contribute the water clarification.As an education practice, high school students and teachers survey the river waters in Osaka Prefecture used a water evaluation index, and teacher gave the class to analyze a result.As a training of teachers, "Example of practicing the environmental education of water" and "Water analyses flow chart" is made, and explanation scientific meaning of environmental education program and water clarification, evaluation of water quality etc. It used as material of environmental education promotion in the education center and the school.This result of the research was announced at various academic societies, and work up the A4 edition 380-page report.
