| Outline of Final Research Achievements |
Deterioration of groundwater quality due to nitrate-nitrogen is becoming serious environmental problem worldwide. In order to improve this problem, new methods for evaluating type and process of denitrification reaction, a key factor of in situ natural purification, are needed to be developed. This study was aimed to develop new methodology for investigating denitrification mechanism and to show its purification ability using stable isotope ratios (for nitrogen, sulfur, and carbon) in multiple ways. We conducted our proposed plan and achieved our goal in 5 years during 2012-2016.
