These calculations are quite labor intensive, slow and tedious. Wetlands store carbon within their plant communities and soil instead of releasing it to the atmosphere as carbon dioxide. Surface-water hydrology is the study of the origin and processes of water in streams and lakes, in nature, and as modified by man. Microbial contamination—both bacterial and viral—of flood waters can cause great concern for use of previously flooded outdoor areas. Test wells are usually 2 to 5 inches in diameter with a steel casing.

Babbitt signed the Groundwater Management Act (Code). Researchers there have developed an "integrated watershed model that will fit together all the available data in a computerized simulation so managers can predict the lake's response to different strategies for reducing nutrient loads" (Crawford, 1998).
