 Hello everyone. My name is Iman Karar. I am a technical water professional with interest and experience in water governance. I am also a member of the IWA Congress Programme Technical Committee and I'm part of Track 6 Dealing with Water Resources. As we know, groundwater forms the invisible part of water resources. It actually makes 30% of the world water resources, which is threatened by over exploitation and depletion, as well as contamination, which is mainly from nitrates, coming from septic tanks, animals, fertilizers, and so on. Vast portion of the world population rely on groundwater for drinking, but its largest use is in agriculture. But groundwater now is finally getting the attention it deserves. The World Water Day this year is also focusing on groundwater, with the theme making the invisible visible. It will be discussed as a main topic in the Track 6, which is Dealing with Water Resources at the IWA Congress this year. The Congress takes place in Copenhagen in September and as we know Denmark has vast experience with groundwater. The Congress will also have a technical tour, which is dedicated to professionals interested in groundwater. So I hope that you will join us at the IWA Congress and I hope to be able to welcome you there. Please refer to the website for more information. Thank you.
