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.

Article Abstract

Growing societal interest to permit animals into retail food outlets presents both risks and benefits to the dining public and consumers. This article summarizes a literature review that evaluated the associated potential public health issues related to this subject. Using the EBSCOhost research protocol and Google search engines between March 2010 and June 2011, the authors have compiled and synthesized scientific research articles, empirical scientific literature, and publicly available news media. While pets are known carriers of bacteria and parasites, among others, the relative risk associated with specific pet-human interactions in the dining public has yet to be established in a clear and consistent manner. Much of the available health-risk-factor evidence reflects pets in domestic conditions and interaction with farm animals. Special consideration is recommended for vulnerable populations such as children, asthmatics, the elderly, pregnant women, and the immunocompromised.

Come learn about how environmental public health (EPH) professionals can help elevate the importance of EPH programs within their health department. Participants will have the opportunity to learn from experienced peers about the connections between EPH and public health accreditation and the steps EPH professionals can take to identify types of documentation that their health department may use to help meet public health accreditation.

In recent years nitrogen in the environment has become a nationwide concern due to the sensitivity of many water bodies to excess nitrogen loading from many different sources, including Onsite Wastewater Systems (OWS). Complimentary to the Florida Onsite Sewage Nitrogen Reduction Strategies study, the Colorado School of Mines evaluated denitrification via subsurface via a soil treatment unit (STU). This presentation will share the rates of denitrification achieved and how to substantially increase them. See how the onsite wastewater treatment system design plays a key role in the removal of nitrogen.

The Rabies Prevention Program at the South Carolina Department of Health and Environmental Control (SC DHEC) recognized that their annual laboratory testing data wasn’t working for them or their constituents, even though they were publicly available. They collaborated with the Bureau of Laboratories and the Department's GIS office to develop a user-friendly mapping application - Rabies By The Numbers. Learn how the information is being leveraged to benefit all stakeholders, and how your data could do the same for you.

Risk communication on the health effects of radon encounters many challenges and requires a variety of risk communication strategies and approaches. The concern over radon exposure and its health effects may vary according to people’s level of knowledge and receptivity. Homeowners in radon-prone areas are usually more informed and have greater concern over those not living in radon-prone areas. The latter group is often found to be resistant to testing. In British Columbia as well as many other parts of the country, some homes have been lying outside of the radon-prone areas have radon levels above the Canadian guideline, which is the reason Health Canada recommends that all homes should be tested.

Over the last five years, the Environment Health Program (EHP) of Health Canada in the British Columbia region has been using a variety of different approaches in their radon risk communications through social media, workshops, webinars, public forums, poster contests, radon distribution maps, public inquiries, tradeshows and conference events, and partnership with different jurisdictions and nongovernmental organizations. The valuable lessons learned from these approaches are discussed in this special report.

Article Abstract

In the study discussed in this article, 27 private drinking water wells located in a rural Colorado mountain community were sampled for radon contamination and compared against (a) the U.S. Environmental Protection Agency’s (U.S. EPA’s) proposed maximum contaminant level (MCL), (b) the U.S. EPA proposed alternate maximum contaminate level (AMCL), and (c) the average radon level measured in the local municipal drinking water system. The data from the authors’ study found that 100% of the wells within the study population had radon levels in excess of the U.S. EPA MCL, 37% were in excess of the U.S. EPA AMCL, and 100% of wells had radon levels greater than that found in the local municipal drinking water system. Radon contamination in one well was found to be 715 times greater than the U.S. EPA MCL, 54 times greater than the U.S. EPA AMLC, and 36,983 times greater than that found in the local municipal drinking water system. According to the research data and the reviewed literature, the results indicate that this population has a unique and elevated contamination profile and suggest that radon-contaminated drinking water from private wells can present a significant public health concern.

Abstract

We investigated an outbreak of eight Legionnaires’ disease cases among persons living in an urban residential community of 60,000 people. Possible environmental sources included two active cooling towers (air-conditioning units for large buildings) <1 km from patient residences, a market misting system, a community-wide water system used for heating and cooling, and potable water. To support a timely public health response, we used real-time polymerase chain reaction (PCR) to identify Legionella DNA in environmental samples within hours of specimen collection. We detected L. pneumophila serogroup 1 DNA only at a power plant cooling tower, supporting the decision to order remediation before culture results were available. An isolate from a power plant cooling tower sample was indistinguishable from a patient isolate by pulsed-field gel electrophoresis, suggesting the cooling tower was the outbreak source. PCR results were available <1 day after sample collection, and culture results were available as early as 5 days after plating. PCR is a valuable tool for identifying Legionella DNA in environmental samples in outbreak settings.
