Instructor: Frank Casey
Contact information: 123 Walster Hall, Phone 231-8577, email francis.casey@ndsu.edu
Office hours: By appointment.
Location and meeting time of class: Civil & Industrial Engineering room 106: 9:30 a.m. – 10:20 a.m. Tuesday and Thursday
Grading:
480: Exam 1 (21%) + Exam 2 (21%) + Final (34%) + Assignments (24%) = 100%
680: Exam 1 (20%) + Exam 2 (20%) + Final (30%) + Assignments (20%) + Project (10%) = 100%
Disabilities:
Any student with disabilities, or others who need special accommodations in this class, are invited to share their concerns or requests with the instructor as soon as possible.
Academic Dishonesty/Plagiarism:
Work in this course must adhere to the Code of Academic Responsibility and Conduct as cited in SECTION 335: CODE OF ACADEMIC RESPONSIBILITY AND CONDUCT
Cheating: If a student cheats on an assignment or exam of this class, then that student will receive a failing grade for that assignment or exam.
Course Objective:
The Objective of this class is to provide an overview of industrial waste disposal concepts and of soil’s interactions with industrial wastes. Once we form a basic understanding of the physical, chemical and organic characteristics of soil we can then begin to understand the interactions of soil with waste and the fate and transport of waste in soils. These fundamental interactions will be used as the basis for developing and understanding waste disposal on soils.
Course Approach:
The focus of this course will be on the chemical and mathematical concepts, which will be used extensively. At times computers will be used, mainly advanced spreadsheet calculations, to understand waste fate and transport and to make predictions.
A Note to the Students:
I will do my best to take apparently complex concepts and break them into their simplest components, then build them up again so that you can have a better understanding of these concepts. This is my first time teaching this course and I am developing the curriculum from scratch so please bear with me as I learn with you, and do not hesitate to interject your concerns.
Optional Textbook:
There was not one main text that covered the topics that I wanted to cover in this course. I will be using four textbook sources throughout the year, as well as my own sources. I have ordered the text Pepper, Gerba and Brusseau. 1996. Pollution Science. ISBN 0-12-550660-0, which is used extensively, but not exclusively. You may purchase this optional book at Varsity Mart.
Syllabus:
The detailed syllabus below is tentative and subject to change as the curriculum of this course develops. We may need to spend less or more time on certain subjects and thus our schedule may need to be amended.
