In the Gaza Strip more than 95 per cent of the water extracted from the aquifer lying underneath it is unfit for human consumption. This stems mainly from long-standing over-extraction, compounded by infiltration of raw sewage and seawater. Chloride and nitrate levels in the water extracted in most areas exceed the levels recommended by the World Health Organization (WHO) for potable water by up to eight times. As Gaza’s population continues to grow, a 2012 UN report predicted that water demand in Gaza would increase by 60 per cent by 2020, while damage to the aquifer may become irreversible.
