Abstract: The water crisis has become very serious today. One-third of the world's population does not have access to safe water. Only three percent of the planet's waters are healthy and suitable for human consumption. Must use materials to reduce toxic chemicals and we use these materials with caution because their release into the environment leads to their penetration into the soil and groundwater which cause pollution. Besides, we should be more careful in consuming water and in our daily work, such as consumption in families and bathing, to consume less water. In irrigation of agriculture, methods we should be used that prevent the wastewater.
