Phosphorus Uptake In Emergent Macrophytes: An Evaluation Of Vermont-Native Wetland Plant Suitability For Floating Treatment Wetland Applications In Urban Stormwater Settings, Kelly Westhelle

UVM Patrick Leahy Honors College Senior Theses

The USEPA’s revised total maximum daily load (TMDL) for Lake Champlain has Vermont scientists and legislators seeking effective means for curbing phosphorus loads in the Lake Champlain Basin. Developed lands are a critical nonpoint source for phosphorus loading, and green stormwater infrastructure (GSI) ecologically and effectively slow and/or capture nutrients and other pollutants characteristic of urban stormwater runoff. Floating treatment wetlands (FTWs), buoyant mats fitted with wetland plants, are an inexpensive and effective option for improving the water quality of runoff. In urban settings, FTWs are frequently applied to wet stormwater ponds as retrofits. While there are studies demonstrating the …
