Estimating time of a middle distillate fuel release in soil can be performed under certain restricting environmental conditions using the Christensen‐Larsen method (CLM). This method is based on the linear correlation between the time since a diesel fuel release and the corresponding value of n ‐heptadecane to pristane ratio ( n ‐C 17 /Pr) but requires knowledge of the initial ratio value. The empirical nature of this method does not, however, allow accounting for variance in the initial fuel value used by CLM. Based on the zero‐order approximation of the Monod model, we have deduced a generalized equation that can be used for estimating release ages of middle distillate fuels with different initial values. When combined with other site‐specific factors, this equation provides a useful tool for the time of release estimates.
