A series of correlation analyses were conducted using 133 datasetsobtained from different nitrate-contaminated sites to find the empirical relationships between denitrification rates andvarious subsurface properties. Based on Pearson’s correlation analysis, the soil organic carbon concentrations showed astatistically significant correlation (r = 0.75, p < 0.05) with the denitrification rates. A linear regression was performed,which could be utilized to effectively determine the site-specific denitrification rate based on the soil organic carbonconcentration of a site. The proposed method is expected to effectively replace the conventional methods which eitherwere too complicated for practical application or impose large uncertainties that might end up with unreliable results.
