Study Guide

REHS/RS Study Guide, NEHA, 2021
261 pages, paperback

Starting in 2020, the NEHA launched the process of revising this study guide to reflect the most recent changes and advancements in environmental health technologies and theories. Incorporating the insights of 29 subject matter experts from across academia, industry, and the regulatory community, paired with references from over 30 scholarly resources, the fifth edition of the REHS/RS Study Guide was thoughtfully compiled and recreated in a fresh visual layout to enhance the reading and studying experience.

The fifth edition includes 15 chapters that provide an overview of each content area for the REHS/RS credential exam. Each chapter covers a different environmental domain and is broken down into standardized sections including Roles and Responsibilities, Recommended Reading, and Test Mapping. At the conclusion of each chapter, there is a collection of sample exam questions to provide exam candidates the opportunity to apply the principles for that domain.

Chapter topics include:

  • General Environmental Health
  • Statutes and Regulations
  • Food Protection
  • Potable Water
  • Wastewater
  • Solid and Hazardous Waste
  • Hazardous Materials
  • Zoonoses, Vectors, Pests, and Poisonous Plants
  • Radiation Protection
  • Occupational Safety and Health
  • Air Quality and Environmental Noise
  • Housing Sanitation and Safety
  • Institutions and Licensed Establishments
  • Swimming Pools and Recreational Facilities
  • Emergency Preparedness

This essential guide is intended for those seeking to obtain the NEHA REHS/RS credential. It provides a general overview of the topics found on the REHS/RS credential exam and helps those studying for the exam identify areas of strength and areas where more study is needed.
