Qalubeya Drain System / Egypt Environmental Studies on Water Quality. (KIT Scientific Reports ; 7578)

The Qalubeya Drain starts in the northern zone of Greater Cairo were all sewage and industrial wastewater, treated or untreated is dumped into this drain. Along its way there are a lot of discharges like agricultural run-offs or untreated urban municipal water. Despite of these facts the water is also used for irrigation of farmland too. In 2007 the water of the Qualubeya drain was analysed for sum parameters, salts, heavy metals and pathogens taking samples at 12 different sites.
