Lab 9 – Soils and Chemical Pollution
Lab 9 is a web-based exercise – Seek out detailed, but concise answers to the questions from reputable
web-based sources (government sites, universities, reputable popular press, etc.) and please include
those sources in your answers. Plagiarism will not be tolerated and will result in a zero for this
assignment.
1.) What is a superfund site? Why and how is the government involved? Research one superfund
site (anywhere in the US) and give a brief description of the contaminant issues and remediation
efforts. (http://www.epa.gov/superfund/index.htm)
2.) Phytoremediation is the utilization of plants for bioremediation efforts. What are some plants
commonly used for this purpose, and what are the contaminants (including metals) they are
known to be helpful in remediating?
3.) Bioremediation using both microbes as well as plants is an in situ method for remediating
contamination issues. Search for a remediation project that involves bioremediation efforts (oil
spills, pesticides, and even brownfields just as examples) and give a brief description of the
contamination issues and remediation efforts. Some of these sites may be companies or
industries detailing projects or products used in these efforts, which are acceptable to use for
sources of information.
4.) Pollinators, bees in particular, have been a topic of much discussion in research as well as in the
popular press due to their recent significant decline in numbers. Why are bees important?
What causes are being linked to their decline? What efforts are underway to boost their overall
numbers? (10 points)
