Once every week or two, Elom Akpo runs out of the principal's office at Tarsakallak School in Aupaluk, Que., jumps into the school truck and cruises the streets of the village, looking for a water delivery truck. This wasn't part of the job description when Akpo took up his duties as principal last January, but it's what he does to keep the only school in the village of 233 open. Tarsakallak School routinely runs out of water. If its reservoirs are not filled before they run dry, Akpo has to send all 60 or so students home.
