Only a third of the city of Goma has access to running water. The remaining two-thirds of the city rely on private water trucks selling water, or, for the majority, walking to the shores of Lake Kivu to fill jerry-cans. Right next to where these people collect their water, cars and motorcycles are washed in the lake water, the oily run-off draining back into the lake. Not far from here, the boats chug in and out of the port, leaving residue in the water.
