OECD(2008) gives the concepts of inaction costs on key environmental challenges including: direct financial costs; total financial costs; total use costs; and total social welfare costs. In analyzing the losses of environmental goods' various values conducted by domestic and foreign researchers, this study suggests the value-cost category of OECD(2008) and other studies; and the indirect use and non-use values of groundwater and other natural environment using the concepts of inaction costs. The studies on the damages and their relationships among human, property, and ecosystem are essential to monetary valuation on the qualitative or quantitative degradation of groundwater and other natural environment.
