BRWA Water Chemisty volunteers gathered at Northland College on the evening on April 1st to test the accuracy of their sampling techniques and equipment. Dr. Sharon Anthony hosted the event in her lab in the Northland College CSE, and helped by preparing standards to test and assisting with oversight. The volunteers did very well - their techniques were sound and their results were accurate. We host at least one water chemistry quality control session each year to help volunteers with any questions or difficulties they may be having, to restock their LaMotte sampling kits, and to ensure that we continue to collect high-quality data. Our thanks to Sharon Anthony and Northland College for hosting this event, and to the volunteers for attending.
