In the past, the water was very polluted. This affects the river itself, underground water and local villages. The main source of pollution is the Arpechim Refinery. Even today, when the filters stop working, the river is again polluted. To stop this disaster, record fines were given recently. However, there are other sources of pollution, like petrol, when oil pipes are broken by thieves. In the lower part of the valley, pollution may accidentally come from local villagers who wash their cars and animals in the river or take construction materials from the riverbed.
