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.

The sanitation situation in India is dreadful. Approximately 600 million people lack toilets. Defecating in the open is not only a health hazard but also leads to sexual assault. The government of India has set a goal to end open defecation by 2019, and knows it will require more than just building lavatories, but also changing habits. This talk will explore how approaches in India can inform the work of EH professionals in the US.

Many non-profits facilitate sanitation, water and energy projects in developing nations. They often implement innovative and cost-effective solutions to deal with the treatment of human waste and protection of drinking water sources, rather than the traditional widely used approach of water to treat waste. This presentation will share one organization’s lessons learned in West Africa during the Ebola outbreak and suggestions for a new approach to human waste treatment in the US.

Between 8,000 and 18,000 hospitalizations in the US each year are due to Legionnaires' disease (LD) caused by exposure to Legionella pneumophila. Due to the ubiquity of the organism, it can be difficult to assess the specific source of Legionella exposure. After this session, you will be able to conduct an exposure assessment of a LD outbreak to show building owners, risk managers and environmental professionals that the source of Legionella is not always the one you first expect.

Article Abstract

The objectives for the study described in this article were to evaluate the fate and transport of onsite wastewater system (OWS)–derived phosphate from a residential system in Beaufort County, North Carolina, and to determine if current OWS setback regulations are sufficient to prevent elevated phosphate discharge to surface waters. Piezometers were installed in nests at different depths adjacent to drainfield trenches and up- and down-gradient of a residential OWS. Groundwater and septic effluent phosphate concentrations, temperature, pH, dissolved oxygen, and electrical conductivity were monitored every two months from February 2011 to October 2011 (five times). The mean groundwater phosphate concentration beneath the OWS (3.05 ± 0.74 mg/L) was not significantly different than septic effluent (2.97 ± 0.76 mg/L) and was elevated relative to background groundwater (0.14 ± 0.12 mg/L). Groundwater phosphate concentrations were inversely related (r2 = .83) to distance from the system. Onsite system setback regulations may have to be increased (>30 m) in some areas to ensure groundwater phosphate concentrations are reduced to background concentrations before discharge to surface waters.

In 2013, FDA initiated its second 10-year study on the occurrence of foodborne illness risk factors within foodservice and retail food facilities. This session will provide industry and regulatory food safety professionals with information on specific food safety practices and procedures that are in most need of attention within the retail food segment of the industry. Attendees will be able to assess the underlying issues that impact employee behaviors and food safety practices and to identify potential intervention strategies that are also being assessed as part of the study.

What we have here is a failure to communicate! Use this session to obtain insights as to why the retail food regulatory inspection process may not be as effective as it could be. Learn how to tailor your communication techniques to make a connection with food worker that will result in positive behavioral change.

Article Abstract

The study described in this article evaluated sources of contamination of children’s food and drinking water in rural households in the highlands of Peru. Samples from children’s meals, drinking water, kitchen utensils, and caregivers’ and children’s hands were analyzed for total coliforms and E. coli counts using Petrifilm EC. Thermotolerant coliforms in water were measured using DelAgua test kits while diarrheagenic E. coli were identified using polymerase chain reaction methods (PCR). Thermotolerant coliforms were found in 48% of all water samples. E. coli was found on 23% of hands, 16% of utensils, and 4% of meals. Kitchen cloths were the item most frequently contaminated with total coliforms (89%) and E. coli (42%).  Diarrheagenic E. coli was found in 33% of drinking water, 27% of meals, and on 23% of kitchen utensils. These findings indicate a need to develop hygiene interventions that focus on specific kitchen utensils and hand washing practices, to reduce the contamination of food, water, and the kitchen environment in these rural settings.

This one-of-a-kind center promotes a hands-on approach to education and showcases both conventional systems and a variety of wastewater treatment alternatives. This session will allow you to rotate in small groups through a number of hands-on workstations featuring above ground low-pressure distribution, various tanks and their components, numerous ATUs, media filters, and performance based treatment systems. FOWA’s Executive Director will also brief you on the ground-breaking policy endeavors happening nationwide, who the players are, and the importance of the role of EH professionals in the creation of policy. Includes a catered lunch from Sonny’s BBQ upon arrival. Education 1:00 pm to 4:00 pm at outdoor work stations.
