After the second world war, and specially in this decade, in consequence of population growth and industrial development, along with the rural migration in direction to urban areas the problems of environmental sanitation are increasing, including pollution control. It is necessary to increase and improve tuition and researches in the field of environmental sanitation, as well as review the programmes needed. Environmental sanitation must be teached from primary school to college. In the schools of Public Health usually it is ministered at the undergraduate level, in courses for students that have already concluded some undergraduate courses, and at the graduate level, as in programmes for ancillary personnel. Some aspects of environmental sanitation could be ministered in shorter specialization courses. The programme of environmental sanitation of any course must be oriented in order to give a broad knowledge in this field, and according to the needs of the country, region or state, and the professional we want to prepare; the role of the school, or, in other words, according to the level of preparation of personnel - International, National, Interstatal or Statal, must influence the programmes of environmental sanitation. Researches must be intensified. In the developed countries as in those undergoing development, the researches must be more practical and simple. Exchange with developed countries could be useful for both.
