Recent field and experimental research has shown that certain classes of subsurface contaminants can biodegrade at many sites. A number of factors influence the rate of biodegradation, which helps determine the ultimate extent of contamination. Estimation of degradation rate constants is necessary for determining the impact of contaminants on environmental receptors. The purpose of this note is to show one method for estimating rate constants from field data that relies upon application of a standard solution of a linear ordinary differential equation (ODE).
