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.

The Department of Environmental Health Engineering of Kermanshah School of Health, in addition to producing science and applying it, has the mission to train graduates with the highest possible scientific and practical quality and to provide knowledge and progress to the country. Achieving the set goals is possible by relying on experienced professors, laboratory facilities and equipment, new technologies and the necessary space. Therefore, the overall goal of the Environmental Health Group is to participate in maintaining and promoting public health by identifying harmful and polluting environmental factors by performing activities such as: planning, design, implementation, monitoring, managerial and educational evaluation based on scientific criteria and controlling hazardous effects of pollutants. And prevent their spread in the environment.

 The Environmental Health Engineering Group intends to act in a community where the organizational motto is to maintain respectful human relations in the field of society by applying participatory management. Therefore, the students in this field can acquire the necessary scientific and practical skills, and also can be an expert to find his place in the society and the labor market by providing his information and knowledge to other fellows.
