Wetlands have been shown to act as natural filters and improve water quality; as spring water flows through a wetland the contamination is decreased. A comparison of water quality in spring and lake water filtered through a wetland versus water from a naturally flowing spring will be presented. Samples were obtained at various sites at a local park that has both stream and spring inlets to a wetland to the west of the park lake and a naturally flowing spring to the east which has not been wetland filtered. The lake samples were expected to be less contaminated as the water flow reached the lake. Samples were tested for the wetlands ability to filter contaminates such as nitrogen, phosphorous, and microbial pathogens.
