Pretty nasty isn't it? Our canals are picturesque if you see them at the right time of day when the light reflects off the surface instead of penetrating to show the rubbish that's accumulated under the water. Riding at dusk, they are streams of quicksilver etched with the ebony images of the trees and passing villagers. Their beauty is breathtaking. If you fall into them you need a serious dose of an anti-parasitic or you risk getting bilharzia (schistosomiasis), and if you drink from them, well, forget it.
It is the nature of the world to incorporate extreme beauty with extreme danger, I think. I just wish that it was the nature of governments worldwide to care more about the welfare of the poorer people who have their lives cut short by a lack of decent water. There are "fresh water" wells dug all over the countryside, but if the wells are not deep enough, they are polluted by the runoff from the fields. Poor people have a hard time scraping up the LE 2000 that it cost me to dig a well that would provide me with non-poisonous water. Where I have a good well, I've installed a tap outside the garden wall so that my neighbours can use the water. But they still wash clothes in the irrigation water.
Rome wasn't built in a day and the Egyptian countryside won't be cleaned up in one either.
