A waste fluid is evaluated to determine if the waste fluid includes fracturing fluid requiring treatment for sodium; a hydrocarbon level requiring hydrocarbon treatment; and/or drilling fluid requiring clay treatment. The waste fluid is mixed with mature compost, organic fertilizer, and top from the well site. If the waste fluid requires treatment for sodium, calcium nitrate is mixed with the waste fluid in an amount sufficient to balance the sodium content thereof. If the waste fluid includes a hydrocarbon level requiring hydrocarbon treatment, an additional organic fertilizer is mixed with the waste fluid along with hydrocarbon-digesting microbes in an amount sufficient to inoculate the waste fluid. If the waste fluid includes drilling fluid requiring clay treatment, the waste fluid is mixed with gypsum to break up and reduce adhesive characteristics of clay particles present in the waste fluid. The mixture is stirred and dried to produce fertile top soil.
