Introduction

Environmental health engineering is the control of factors in the living environment that in some way affect the physical, mental and social health of human beings. For the first time, a sanitation school was established in 1973 with the aim of training trained environmental health personnel for 6 western provinces of the country. In this educational center, students were admitted through regional free exams from 6 central provinces, Lorestan, Hamedan, Ilam, Kurdistan and Kermanshah, and at the same time they were employed by the former Ministry of Health and after a one-year training course, they started working. From 1982 onwards, he alternately hired employees of the Ministry of Health who had previously completed a three-month course in environmental health as an environmental health assistant.

The first environmental health associate course was established in the academic year of 1988-2009, and among the holders of the degree of rehabilitation assistance, they entered the paramedical and health school to complete the courses. In 1993, the admission of students in the field of environmental health for associate degree began freely. In 1995, the bachelor's degree program was approved and in the 1996-97 semesters, 15 students were admitted to the mentioned course. Also, with the admission of 30 undergraduate students and 5 masters of environmental health engineering in the semester of 2008-2009, the group continued its activities. In 2016, the first doctoral student admission course was launched and approved, and the first postdoctoral of the faculty in 2018 from the Department of Environmental Health Engineering was graduated. Currently, the number of undergraduate students in this group is 93 and the number of master students studying in this group is 20. It should also be noted that since 2001, more than 650 graduates have had environmental health engineering.
