Alarmingly, unpublished studies conducted by Basem Shomar, from the Institute of Environmental Geochemistry in Heidelberg, suggest a 50 per cent incidence rate of methemoglobinemia in the region's newborns. The disorder - which cuts down the amount of oxygen blood can carry, and leads to blue skin, diarrhoea, vomiting, and sometimes death - is known to be triggered by nitrate-contaminated water.
Israel understands perfectly the health effects of this water contamination.
However, the electricity plants which run the water filtration facilities are not functioning well, and Israel refuses to allow badly needed equipment for these plants to get to Gaza.
If it looks as though this poisoning of the Gazan people is deliberate, it's because it is.
