The aim of ICEPR'15 is to bring together the Canadian and international community working in the field of environmental sciences, engineering, and technology, and to foster an environment conducive to present advances in this field. This conference will also provide a golden opportunity to develop new collaborations and gather world experts on the different topics including pollution detection, environmental remediation, and pollution prevention. Through the fifth conference, a great opportunity to share knowledge and expertise will be created by taking advantage of the synergy that was formed in preceding conferences. ICEPR'15 will include invited keynote talks, oral presentation sessions, and poster sessions who will demonstrate new and exciting research in the fields.
