Floods and flooding often result in widespread contamination that poses both immediate and long-term threats to human health and the environment. The environmental consequences of flooding, however, can be extremely complex and difficult to assess due to their large spatial extent, multiple sources, sinks, and types of pollutants, and potential effects on nearly all components of the environment. Using Grand Forks, North Dakota as a "backyard laboratory", the proposed research will determine the magnitude, nature, and extent of environmental contamination by heating oil as a result of flooding. Specifically, the proposed research will use the recent pollution of the Red River Valley with home heating oil, caused by the 1997 flood, as a case study. Based on the most significant problems identified as a result of that event, specific objectives for this work are as follows:
- 1. an assessment of human exposure to heating oil vapors in homes following
the spilling of large amounts (e.g., 260 gallons) of oil; and
2. the development of methods for the efficient remediation of heating oil from contaminated building materials.
The project employs a coordinated, multidisciplinary approach to addressing the effects of heating oil contamination on the environment and human health. In addition to the laboratory studies, the proposed research will take advantage of the natural outdoor laboratory in Grand Forks generated by the Red River of the north flood in 1997. Specifically, several field studies are proposed which will involve simulating flood conditions in homes in order to determine the fate (i.e., sinks, transport pathways, and mechanisms) of heating oil contamination. Following this work, bioremediation measures will be studied in the laboratory and then applied in the field in order to identify heating oil clean-up methodologies.
The proposed work will result in:
- 1. an assessment of the magnitude of the problem of flood-related environmental
contamination (with respect to heating oil in this study);
2. post-flood strategies for dealing with chemical contamination;
3. Best environmental practices in flood-prone areas; and
4. decreased risks of disaster-related human health problems.
