Health Risk Assessment, Surveillance & Management

Environmental Health Risk Assessment Publications

Last Updated: December 15, 2017

​The Environmental Health Risk Assessment Division conducts health risk assessments, advises decision-makers on health risk management issues, and develops technical guidance and manuals for assessing and managing health risks associated with chemical and microbiological hazards that may be found in the environment.  Selected publications and technical guidance and manuals are provided here.


Public Health Information Paper 39-01-0514, Microbial Risk Assessment for Unrestricted Wastewater Reuse During Army Deployments

This assessment evaluates microbial health risks associated with wastewater reuse in deployed settings.  The assessment  uses Escherichia coli concentration as a measure of risk from exposure to microbial pathogens that might be found in treated wastewater.  The risk assessment provides background on the need for considering treated wastewater reuse, explains why E. coli was selected to measure microbial risk, and provides details of the risk assessment and associated scientific uncertainties.  Risk-based water concentrations (RBWCs) were developed for E. coli for full-body contact activities (e.g., showering) under various exposure assumptions.  The report provides information and guidance for setting a microbial standard for unrestricted reuse of treated wastewater using currently fielded measurement equipment.  The supplements provide additional detail on interpreting the risk estimates.

Public Health Information Paper 39-04-0116, Development of Exposure Guidelines for Chronic Health Effects Following Acute Exposures to Toxic Industrial Chemicals – A Toxidrome-Based Approach 

This paper describes a toxidrome-based approach to developing exposure guidelines for assessing the risk of chronic health effects following acute exposures to toxic industrial chemicals (TICs).  The approach relies on subject matter expert input to bridge the key data gaps.  A working example with notional data is provided to illustrate how the approach could be applied.

Public Health Information Paper 39-05-1016, The Microbiome and Health Risk Assessment: Workshop Summary 

This paper summarizes the proceedings of a workshop organized to bring together subject matter experts to share their knowledge of microbiome-chemical interactions, and discuss strategies for targeted research that will support the integration of microbiome data and insights into health risk assessment. The workshop was held on 20 April 2016 at Defense Health Headquarters, Falls Church, Virginia.  Associated Documents: PHIP-39-05-1016Date: December 2016

  Public Health Information Paper 39-06-0417, Review of the Applicability of Published Water Reuse Guidelines for Contingency Operations 

This paper reviews the currently available water reuse standards for gray water and assesses their applicability to water reuse for specific activities performed in contingency operations.  The most common water reuse source stream is comprised of laundry, showering, and dishwashing wastewaters. The resulting assessment is intended to enhance risk analyses and guideline development regarding military water reuse.   Associated Documents: PHIP-39-06-0417 Date: April 2017



TECHNICAL GUIDES   Technical Guide 230 - Environmental Health Risk Assessment and Chemical Exposure Guidelines for Deployed Military Personnel   

TG230 provides a standard methodology for characterizing chemical exposure health risks at deployment locations in a manner that is consistent with military risk management doctrine.  Health-based, military exposure guidelines (MEGs) for chemicals are presented for air, water, and soil associated with various deployment exposure scenarios.

Date: December 2013

Current Status:  The 2013 Revision is now posted.  The RD230 document did not change from 2010, but there is an RD230 Addendum.  The MEG quality improvement initiative continues.  

Technical Guide 248 - Guide for Deployed Preventive Medicine Personnel on Health Risk Management

TG248 introduces the processes and tools that can be used to make appropriate decisions based on medical threats.  It is written for preventive medicine personnel who are assigned the task of providing deployment health risk assessments to the commander based on Occupational and Environmental Hazard and Endemic Disease (OEH/ED) surveillance.

DateAugust 2001

Current Status:  An administrative review was performed and TG248 was certified current October 2010.  With the planned revisions to DA PAM 40-11 (Preventive Medicine), this TG will likely be phased out.

 Technical Guide 254 - Standard Practice for Wildlife Toxicity Reference Values

TG254 establishes a standard methodology for generating, supporting, and documenting defensible wildlife toxicity reference values (TRVs) for chemicals of interest in Army ecological risk assessments.

Date: October 2000

Current Status:  TG254 is a USAPHC legacy publication under review. 

Technical Guide 312 - Health Risk Assessment Methods and Screening Levels for Evaluating Office Worker Exposures to Contaminants on Indoor Surfaces Using Surface Wipe Data

TG312 provides a method for evaluating potential health risks to office workers from exposure to chemical substances on indoor work surfaces. This technical guide is intended to provide users with the option of conducting a screening analysis or a site-specific characterization of potential health risks from exposure to contaminants.

Associated Documents: TG312

Date: June 2009

Current Status:   This technical guide is undergoing an update and will be posted here when complete.

Technical Guide 316 - Microbial Risk Assessment for Aerosolized Microorganisms (and TG316 Supplements)

TG316 provides a general methodology framework for assessing aerosolized microbial hazards and characterize risk as a result of environmental, occupational, or intentional exposures. The TG outlines the considerations and steps necessary to complete a microbial risk assessment.  It is designed to be used as a preplanning or post-event tool.  Stand-alone TG 316 supplements provide specific information and risk assessment tools, to include biological military exposure guidelines (BMEGs).
