During a structural integrity assessment of the storage tanks, it was discovered that one of the 10,000-barrel gasoline storage tank was leaking. As the tank was located in a tank farm with an earthen bund wall, a large quantity of the gasoline seeped into the soil beneath the tank. Since the discovery, the company has embarked on a rigorous programme to select an appropriate treatment method for the contaminated soil. Assist by answering the following questions. Questions 1. Describe two (2) ex-situ treatment methods that could be applied to treat the gasoline- contaminated soil. Outline the steps involved in the selected processes. 2. List two advantages and disadvantages of using ex-situ methods for soil remediation in the above scenario. 3. Based on the distinct advantages associated with Monitored Natural Attenuation (MNA), the company would like to explore this option. a. What are the different forms in which the spilled product would exist in the soil subsurface? b. Justify the use of this method for remediating the contaminated soil. c. Describe four (4) factors that must be considered for the effective growth of microorganisms that would use the contaminants as substrates. |
