Conclusion

As my hypothesis stated, Sligo Creek was more polluted than Sleepy. This probably is owed to the fact that we have more pollution because we live in an urban area. Urban areas have more pollution and litter. Pollution is caused by bacteria, sewage, or chmicals. Because both creeks drain into the Chesapeake Bay, the pollution in Sligo contributes to the pollution in the Bay. I think that the pollution in Sligo is caused by bacteria in droppings and sewage. This could be a hypothesis for a new experiment.
