Abstract: Turbidity is the single most prevalent form of water pollution in Minnesota, but measurements of it are sparse in either space or time. We propose to develop a low-cost turbidity sensor that can differentiate dissolved and suspended load, help to quantify and mitigate land-use practices that lead to soil loss, and be easily deployed across Minnesota and beyond. Laboratory and field testing and deployment of this new sensor will guide its development, improve monitoring of post-logging erosion, and produce immediate data on water quality in agricultural southern Minnesota with unprecedented temporal resolution.
