The Monitoring of the Groundwater and the Drilling Mud Stabilization Method, at the Ogra Specific Waste Deposit, Mures County

Abstract

The paper describes the composition of one environmental factor, namely groundwater, which is monitored at the specific waste deposit in Ogra. Due to the modern processing technology of the drilling mud resulted from natural gas extraction, in the specific waste deposit in Ogra, Mures county, as well as to the treating method of these wastes using a specific recipe and to the safety measures consisting in the impermeabilization of this deposit, a minimum environmental impact of the treated and deposited wastes is ensured. In order to determine the indices analyzed in the laboratory, some witness samples from the underground water in the control shaft and the respective collected leachate were sampled. According to the results of these analyses, the wastes’ aggressiveness towards the groundwater-soil complex can be established.
