Identify Impaired Waters
Many of Wisconsins water quality standards require multiple visits to make an assessment decision. Every year, several stream sites are monitored and the field data collected during each visit are used to flag problem waters. In the next year, follow up monitoring is carried out on the flagged waters where the data suggest there is an impairment, but there are insufficient data to make that determination based on the States minimum data requirements. In 2015, Water Action Volunteers stream monitors who live nearby the recommended follow up sites were asked to assist in the monitoring process by collecting water samples to be analyzed for total phosphorus at the Wisconsin State Lab of Hygiene.
