3. Final Design

4. System Integration Two problems occurred during building: 1.Bolts were too short- easily fixed by getting longer bolts. Issue occurred due to a measurement assumption. 2. Placed mesh on wrong side of lid assembly Was not possible to fix but was able to use it for taste testing So far no problems have occurred that will prevent the collection of data.

6. Turbidity & Flow Rate Testing Update Testing performed on water from pond near Global Village Genesee River was frozen over Three prototypes have been used to test how well the assembly works Testing has been successful! We plan to continue flow and turbidity tests through the first week in April. – Genesee River water – Custom water (varying levels of sand and soil added to tap water)
