A method and liner for a reserve earthen pit for use in onshore drilling operations has a foamed polymeric composition. At least one layer of the continuous foamed polymeric composition is applied to the interior surface of the reserve earthen pit, preferably after the native soil has been compacted, thereby forming a sealed liner barrier between the native soil and the interior of the pit. The composition is resistant degradation from the drilling muds that are stored within the pit. UV protectants may also be added to the pit liner composition.
