At 6 am on the third Tuesday of the month, volunteers meet their partners at their assigned sampling locations along the Charles River. Volunteers collect a water sample in the sterile bottle provided and measure the water temperature and depth. Volunteers then deliver their sample and data sheet to the assigned drop-off location and collect materials for the next month's sampling event.
