EHPLE Public Health study guide
EHPLE Public Health · Work through your exam, one topic at a time.
The EHPLE Public Health credential is aimed at environmental health practitioners who inspect, permit, investigate, and advise on the conditions that shape community health - food establishments, drinking-water and wastewater systems, air pollution sources, vector and housing hazards, and the surveillance systems that detect problems early. The examination tests applied judgment across seven domains: environmental health sciences and exposure assessment (20%), epidemiology and public health surveillance (18%), law, regulation, and policy (15%), food safety and protection (14%), water quality and wastewater management (13%), air quality and environmental health risk (12%), and professional practice and program management (8%). The EHPLE Public Health study guide has 7 sections and about 3,487 words.
01Environmental Health Sciences and Exposure Assessment
This domain tests the scientific engine behind every environmental health decision: how a contaminant leaves a source, moves through air, water, soil or food, reaches a receptor, and what dose the receptor actually receives. Questions usually pair a calculation with a judgement about which pathway dominates or which default assumption is defensible.
530 words, about 3 min02Epidemiology and Public Health Surveillance
This domain tests whether you can measure disease occurrence, compare groups correctly, recognise the design that produced a number, and run or interpret a surveillance signal. Expect 2×2 tables, attack rates, screening statistics and questions about bias.
526 words, about 3 min03Environmental Health Law, Regulation, and Policy
This domain tests how environmental standards are created, implemented, challenged and enforced. You should know the statutory architecture, the difference between health-based and technology-based requirements, and how administrative procedure constrains agencies.
478 words, about 2 min04Food Safety and Protection
This domain tests how biological, chemical and physical hazards are prevented, eliminated or reduced across production, processing, retail and outbreak response. Expect HACCP mechanics, temperature standards, pathogen ecology and recall classification.
494 words, about 2 min05Water Quality and Wastewater Management
This domain tests the barriers that keep drinking water safe, the treatment that makes wastewater safe to discharge, and the regulatory numbers attached to both. Expect treatment-train reasoning, disinfection calculations and pollutant limits.
472 words, about 2 min06Air Quality and Environmental Health Risk
This domain tests how air pollutants form, are measured, are regulated and are translated into health risk. Expect criteria pollutant standards, dispersion basics, indoor air and inhalation risk calculations.
485 words, about 2 min07Professional Practice and Program Management
This domain tests whether you can run an environmental health program: identify needs, set defensible objectives, deploy limited resources, evaluate honestly and communicate risk without losing public trust. Assess needs (data, inspection findings, complaints, disease rates, vulnerable populations) → prioritise using magnitude, severity, equity and preventability → write objectives → design activities → implement → evaluate → reassess.
