What Is an REHS/RS Credential?

No issues are more important to the communities in which we live and work than clean air, safe food, and potable water. An individual with an REHS/RS credential has the skill set to ensure that these basic community necessities are met, as well as manage other critical functions such as emergency response, vector control, sewage sanitation, hazardous material handling, and more.

The REHS/RS is the most prevalent NEHA credential and professionals demonstrate competency in an impressive range of environmental health issues, directing and training personnel to respond to routine or emergency environmental situations, and providing education to their communities on environmental health concerns. In addition, REHS/RS credential holders are key members in ensuring communities are in compliance with local, state, and federal environmental health regulations.
