This is distressing news. Many Iraqis do not appear to have good drinking water.
On the other hand, according to the article, this problem has been going on for at least 30 years, so it can't be blamed on the invasion or even on the sanctions - at least in this case. (There have been reports that the sanctions crippled Iraqi water purification, although in the cases mentioned it appears that there wasn't good purification in the first place).
That is all.
