In the fall of 2009 someone dropped the 1979 Cherry Film Production Ltd movie "groundwater" on the desk of Harm Maathuis. Heck, what do you do with a 16 mm movie and no projector. So, Harm had the movie converted into a DVD and gave the original to the University of Waterloo. With permission, he has now made it available to the IAH-CNC. This film is a piece of history and is the only Canadian based film on the subject of groundwater. We thought it would be nice to place it on the IAH-CNC website for your viewing pleasure.
