Automated storm water sampling

A researcher tests water quality.

District 8 requested water monitoring for the TH 23 reconstruction project. Information was needed on the in-place point source discharge of the City of Spicer storm sewer. A site was installed at the end of Manitoba Street near Green Lake on August 16, 1999. Rain, level and flow data were monitored remotely for one year. Automatic samples were taken during rain and snowmelt events. The equipment was then moved in October 2000 to Lake Avenue off Salisbury Beach, which is not far from the original site. Rain, level and flow data are downloaded remotely to watch for sample events. Automatic samples from rain or snowmelt events are taken periodically for testing. Monitoring ended June 30, 2011.
