This helps us validate your data for others to use, part of your quality assurance and control responsibilities and one of the performance criteria for participation. The third purpose is to answer any questions you are your students might have, stock up your supplies, take your samples and our chance to meet the volunteers that care for our rivers. Our goal for the future remains to have more time at each visit and to schedule them at a time more convenient for you. Time is of the essence for us to be efficient and effective at the visits. We try not to change the schedule once it is in print.
Students also prepare a dissolved oxygen test and titrate that.
Students then simulate or describe sample collection procedures, including blanks and duplicates. We check your sample tracking number against our records. We bring the data sheets from the Sample Plan, Chapter 5, but you can have them copied as well. Students DO NOT need to have instructions memorized, just be able to read and perform them. We, the RW staff, will titrate a water sample with our green box AND your green box while the students are doing their tests.
