THE POSSIBILITY OF USING DRILING WASTEWATER IN THE REMEDIATION OF DISTURBED LAND

Abstract

The paper examines the possibility of using drilling wastewater in the remediation of disturbed land. The samples were examined using concentration meter, spectrophometer, and pH meter. Studies on the metal content were carried out by atomic emission spectrometry with inductively coupled plasma. It was found that the liquid drilling waste contains a complex of biophilic elements: N, Ca, Na, K, P, S, Cl, Fe, Cu, Co, Mn, Zn. Three soil plots for sowing grasses on liquid drilling waste were studied. The soil was furrowed and the grass mixture was sown using working solutions. The possibility of using drilling wastewater as a meliorant in the conditions of forest-tundra and tundra zones of the Krasnoyarsk Territory has been established. The results of experimental data indicate that the use of components of liquid drilling waste in the formulation of agrochemical preparations does not have a negative effect on seed germination and plant growth.
