Name: ___ / 100 points Discussion Section: Problem Set 6 ESPM 15: Introduction to Environmental Science Due in hardcopy at the beginning of lecture (9:10 am) on Friday, March 18, 2016 1. The Clean Air Act of 1963 and Clean Water Act of 1972 inadvertently led to a mass development of methods to dispose of toxic material into the ground. List and briefly describe the 3 methods of ground disposal of contaminants discussed in Lecture 18. Include at least one potential failure of each. ___ / 15 points (2.5 pts each) 1. Method: Deep well injection – drill a well to inject hazardous waste below water table into porous geological formations. Potential failure(s): Possible Answers: Wells can corrode and leak waste. Well lining can break when fissures develop. Hazardous waste can contaminate soil and groundwater. 2. Method: Surface impoundment – waste water is put in a pond lined by impervious material such as clay. Waste water evaporates, leaving behind hazardous material. Potential failure(s): Possible Answers: Volatile hazardous waste evaporates to atmosphere, polluting air. High rainfall causes to overflow. Leakage in impervious clay liner. 3. Method: Landfills – Reactive waste placed in separate cells and put in ground capped and lined by impervious clay. Monitoring well provides data on any potential leakage.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
