ABSTRACT OF THE DISCLOSURE A process for on-site disposal of well site sump liquid after completion of drilling at the site. Surface soil at the well site is loosened and piled into windrows. A trench is excavated adjacent to the windrows. The windrows are sprayed periodically with part of the sump liquid so as to maintain them at least partially saturated, while allowing for evaporation. A further portion of the sump liquid is pumped into the trench, and both the dirt previously excavated from the trench and the windrows are pushed or otherwise directed into the trench.
