MODULE 6 Project Assignment: Evaluation of Treatment Technologies and Alternatives (individual
Depending on the type of contaminant (Atrazine) that you have chosen, and the potential contamination scenarios
associated with that compound, you may do one of the following for this task (please make sure to consult
with your team members regarding this decision):
1) Pick a contamination scenario (i.e. a contaminated matrix, such as e.g. soil or groundwater) and
describe potential treatment technologies or alternatives for this scenario,
2) Describe applicable treatment technologies or alternatives for various contamination scenarios
for your chosen compound.
(Note: a treatment alternative may include a combination of treatment technologies.)
You may want to choose the first approach if you have picked a contaminant that may be treated using a
wide variety of methods, for which there is a lot of available information, but you’d like to research only
a few of those technologies in more detail. The second approach is more applicable if your contaminant
is typically treated by only 1 or 2 different technologies for a given matrix and if the contaminant is also
present in various matrices. This second approach is also appropriate if you are interested in gaining a
“big picture” overview of available treatment technologies for a given compound.
For either case, discuss at least 4-5 different technologies in detail. At the very least, make sure that you
include information on the following for each technology: (1) the history and frequency of current use of
the technology to treat your contaminant in a given matrix, (2) a basic description of the technology
including a summary of the processes involved in treatment, and (3) the advantages and limitations
associated with the technology. You may also discuss case studies where the technology was applied to
treat your chosen contaminant. You should conclude your work with a critical evaluation/comparison of
the various technologies in terms of expected treatment effectiveness as well as advantages and
disadvantages of one technology over the other.
