OBJECTIVE - To find a relationship between the water quality and number of zebra mussels shells in one square meter along the Upper Mississippi River.
HYPOTHESIS - There are more zebra mussel shells in locations where there is poorer water quality (ow dissolved oxygen concentrations, high phosphate concentrations, high nitrate concentration, and/or pH levels of 4, 5, 9 or 10).TEST FACTORS -
CONCLUSION- The experiment showed no relationship between the water quality and amount of zebra mussel shells. This was concluded because not all of the locations tested were the appropriate places to find the zebra mussel shells. The water quality of an area has little effect on the zebra mussels. Zebra mussels are very tolerant to pollution and change in their environment and this is one of the qualities that enable them to thrive in watersheds. This is a major concern for the Great Lakes, Mississippi River and inland lakes because they clog water in-take systems of power plants and water treatment facilities, and the cooling systems of boat engines. They have severely reduced, and may eliminate native mussel species. In order to stop the spread of zebra mussels boater should completely drain all water from their trailer, boats, and motor. They should wash everything using hot water, pressure washers, and dry boats and trailers in the sun at least four days before used in uninfected waters.
