Abstract
Water on earth is present in abundance but only 1% of this is available for human
health. Environmental pollution and water pollution are increasing day by day
due to the urbanization and industrialization. Release of discharge from urbanization and effluent from industries is the major concern of pollution and it’s the
threat to humanity. So there is dying need to develop new technologies and
method for water remediation. Nanotechnology is the technology which meets
many of the above conditions. Nanomaterials and their properties make these
highly beneficial technologies for water remediation. This chapter is an overview
of nanomaterials for water remediation.

Introduction
Water is the main source for all the living beings on the earth and the environmental
pollution have serious impact on the fresh water supply (Crittenden et al. 2005; Mara
2003; Moore et al. 2003; Johnson et al. 2008). Almost 10–20 million people die
every year due to water borne infections and nonfatal infections cause about
20million deaths. Unavailability of safe water is the major problem and 0.78 billion
people around world do not have safe drinking water (Montgomery and Elimelech
2007; Theron and Cloete 2002; Eshelby 2007). The unmanageable pollution and
