Natural Source Zone Depletion (NSZD) is the collective natural processes that reduce the mass, saturation, and mobility of light non-aqueous phase liquid (LNAPL) in the subsurface. These processes include volatilization, dissolution, and biodegradation. NSZD of the LNAPL begins from the moment the release occurs and understanding it is a critic…
