Johann Hari: Israel is suppressing a secret it must face

But I can't do it. Whenever I try to mouth these words, a remembered smell fills my nostrils. It is the smell of shit. Across the occupied West Bank, raw untreated sewage is pumped every day out of the Jewish settlements, along large metal pipes, straight onto Palestinian land. From there, it can enter the groundwater and the reservoirs, and become a poison.

Standing near one of these long, stinking brown-and-yellow rivers of waste recently, the local chief medical officer, Dr Bassam Said Nadi, explained to me: "Recently there were very heavy rains, and the shit started to flow into the reservoir that provides water for this whole area. I knew that if we didn't act, people would die. We had to alert everyone not to drink the water for over a week, and distribute bottles. We were lucky it was spotted. Next time..." He shook his head in fear. This is no freak: a 2004 report by Friends of the Earth found that only six per cent of Israeli settlements adequately treat their sewage.

Meanwhile, in order to punish the population of Gaza for voting "the wrong way", the Israeli army are not allowing past the checkpoints any replacements for the pipes and cement needed to keep the sewage system working. The result? Vast stagnant pools of waste are being held within fragile dykes across the strip, and rotting. Last March, one of them burst, drowning a nine-month-old baby and his elderly grandmother in a tsunami of human waste. The Centre on Housing Rights warns that one heavy rainfall could send 1.5m cubic metres of faeces flowing all over Gaza, causing "a humanitarian and environmental disaster of epic proportions".
