SPATIAL AND TEMPORAL VARIABILITY IN STREAM WATER QUALITY ALONG A RURAL-TO-URBAN GRADIENT
Hinkson Creek watershed is a multi-land-use watershed located in Boone County, Missouri, that runs through the city of Columbia. Hinkson Creek has failed to meet water quality standards for aquatic life since 1998. Consequently, a Collaborative Adaptive Management plan was put in place to guide remediation actions using a science-based approach. As a part of this plan, we started a monitoring effort with broad spatial coverage and spanning different hydrologic conditions to capture pollutant hotspots and hot moments at the Hinkson main stem and tributaries. Here we present the results of nine synoptic samplings that occurred between 2018 and 2020. Our results show that agriculture pollution signals show a strong seasonality, whereas urban pollution signals persevere across streamflow conditions and seasons. We observed maximum chloride concentrations during summer, under baseflow conditions, indicating potentially extended effects of winter road salt applications.
