As part of NEHA's continuos effort to provide convenient access to information and resources, we have gathered together for you the links in this section. Our mission is "to advance the environmental health and protection professional for the purpose of providing a healthful environment for all,” as well as to educate and inform those outside the profession.


Private wells are unregulated and often at risk for arsenic contamination. Research objectives included distribution of groundwater arsenic concentrations, identification of arsenic sources, and establishment of best practices for well construction to minimize risk for wells in Cerro Gordo County, Iowa. We sampled 68 wells over 3 years with 393 water samples and 79 rock samples. Geochemical modeling was used to better understand arsenic mobilization. Arsenic in groundwater ranged from 1.0 to less than 10.0 μg/L for 75 water samples and 31 water samples had arsenic concentrations greater than or equal to 10 μg/L. The arsenic source is naturally occurring sulfide minerals (typically pyrite) in the bedrock aquifers. The shallow (100–150 feet) Lime Creek Aquifer was most at risk for arsenic. Arsenic is likely mobilized from the rock into the water in the shallow aquifer under more oxidizing conditions, subject to water level changes. The study resulted in a policy change for arsenic testing and well completion in Cerro Gordo County to better protect domestic well users.

Emergency Public Health provides a unique and practical framework for disaster response planning at local, state, and national levels. This is the first book of its kind to systematically address the issues in a range of environmental public health emergencies brought on by natural calamity, terrorism, industrial accident, or infectious disease. It features historical perspectives on a public health crisis, an analysis of preparedness, and a practical, relevant case study on the emergency response. Study reference for NEHA’s REHS/RS exam.

Pharmaceuticals are emerging contaminants in water and, to date, cannot be removed as part of wastewater treatment options. So what can be done to mitigate their effects upon the environment, yet maintain their efficacy for human and animal use? In this session, we examine this topic from a lifecycle approach using hands-on demonstrations, and discuss several solutions and policies you can take home to mitigate and address these contaminants in your community.

What type of consumer products do you interact with on a daily basis and do they contain nano-particles? What properties might those engineered iron, titanium and carbon nano-particles exhibit that differ from the norm? What type of information do environmental health professionals need to prevent exposures that might cause negative biological effects? This session will give you the facts so you can adapt to the rapidly changing intersection of health and environment.

As the local food movement continues to gain momentum, more food establishments are demanding produce from small, local farms that may not practicing safe growing and handling practices. Yavapai County, Arizona convened local restaurants, farms, educational and government agencies to develop tools to help both food establishments and farmers to offer safe, local produce. This session will highlight how to work with outside partners to develop innovative approaches to meeting the needs of the ever changing scope of environmental health.

Chemical incidents involving major chemical facilities and transport of toxic industrial chemicals are surprisingly common and may result in widespread environmental contamination, public exposure, and subsequent acute and chronic health effects.

This session includes an interactive demonstration of the applicability of an e-learning tool to actual events by means of working through a major chemical incident. Discover how employing this resource can help you respond more effectively to chemical incidents, thereby protecting public health.

Updated and reviewed by leading experts in the field, this revised edition offers new coverage of industrial solid wastes utilization and disposal, the use of surveying in environmental engineering and land use planning, and environmental assessment. Stressing the practicality and appropriateness of treatment, the sixth edition provides realistic solutions for the practicing public health official or environmental engineer.

Though physiological effects of exposure to airborne lead on cognitive function and crime have been discussed in literature, to date, no studies examined other outdoor or ambient air pollutants and their potential impact on reported crime. Data were collected through open public records provided by study location municipalities to assess the impact of outdoor air pollution on daily crime rates in Chicago, Houston, Philadelphia, and Seattle. Poisson regression analyses were performed to examine associations between outdoor air concentrations of carbon monoxide (CO), particulate matter (PM) including fine (PM2.5) and coarse (PM10) respirable fractions, ozone (O3), and sulfur dioxide (SO2) with several types of crime along with weather variables known to correlate with air pollution concentrations and/or impact crime. Increased PM2.5 was associated with increases in assault, damage, and theft crimes. Pollutants known to cause irritation, like PM10 and O3, were associated with decreases in crime rates. Weather variables were also found to be associated with increases in crime rates when apparent temperature, cloud cover, visibility, and wind speed increased from the 25th to 75th percentile of measurements. Additional research to further understand potential relationships between outdoor air quality and crime is needed.
