City of Janesville and school district team up to study leaf management

This fall, Craig and Parker High School students in environmental science and communications technology classes will assist the City of Janesville in an important study related to leaf management and stormwater quality. The City is collecting data for the United States Geological Survey (USGS) regarding municipal leaf management activities and the effects on waterway pollutants.
The Rock River is recognized as an impaired waterway, with phosphorous being one of the leading pollutants in the river. High levels of phosphorous can cause toxic algae blooms, weeds, depleted oxygen levels, reduced water clarity and reduced recreational opportunities. Leaves are a major source of phosphorous within the City, and leaves in the street can contribute to contamination in the river.
The City’s study will focus on residential streets near Craig High School. Residents have been instructed to manage their leaves differently depending on their street. Throughout the study period, City staff and students will collect data about the leaf management practices and the potential impacts on phosphorous contamination in the river. The results of this study, along with other USGS work, will be used to help shape the City’s future leaf collection program.
