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.


In King County, Washington, the most frequently used alternative solvent to perchloroethylene is a hydrotreated petroleum hydrocarbon. The objectives of the authors’ study were to 1) determine the frequency of use of process chemicals used in “hydrocarbon” dry cleaning and gather other operational information; 2) chemically characterize the process chemicals; 3) characterize the still bottoms and separator water wastes according to dangerous waste and wastewater discharge regulations; 4) identify linkages between work practices, process chemicals, and the chemical composition of the waste streams; and 5) evaluate the aquatic toxicity of the hydrocarbon solvent and detergent. Many hydrocarbon dry cleaners are using process chemicals that contain hazardous substances, including trichloroethylene. One sample of separator water contained 13,000 µg/L trichloroethylene. This sample was determined to be federal hazardous waste, state-only dangerous waste (i.e., according to Washington state-specific regulations), and failed wastewater discharge thresholds. All still bottoms were determined to be state-only dangerous wastes. Efforts should be directed towards replacing hazardous spot cleaning chemicals with safer alternatives and ensuring that wastes are disposed of appropriately.

Efforts to characterize environmental health workers (EHWs) are needed in order to strengthen the field. Data from the 2014 Public Health Workforce Interests and Needs Survey were used to describe the self-reported roles, important daily work tasks, and skill gaps of EHWs and to compare and contrast these characteristics between state health agencies (SHAs) and local health departments (LHDs). While EHWs at SHAs and LHDs share overall similarities in terms of important daily work tasks and skill gaps, the differences could reflect that the strengths of local-level environmental work fall within communicating and community interaction, whereas state-level strengths reside in administrative, policy, and scientific functions. Our findings also highlight a need for EHWs to strengthen their skills in budget- and policy-related competencies, especially at the local level. We found that number of years in current position was a significant predictor of the number of skill gaps, suggesting the utility of a peer-learning network.

The movement and requirements for Green cleaning has sparked innovation in retail food sanitation. New chemical-free cleaning and sanitizing systems are being used in selected food establishments with surprising results. Several of these innovative systems are listed with NSF under new and rigorous Protocols and meet current standards. Several of these extreme Green technologies will be highlighted and contrasted. Attendees will evaluate these solutions against standards and leave with a knowledge of current cleaning innovations.

Restroom internal door handles have the potential to become contaminated by pathogenic bacteria, particularly because frequent breakdowns occur in hand hygiene. Cleaning these door handles periodically could reduce this cross-contamination risk. The sustained effect following cleaning with chlorhexidine could be beneficial in restroom facilities as cleaning episodes are of necessity at time intervals. The cleaning efficacies and residual effects of Sani Cloth CHG 2% wipes were investigated in a double-blinded randomized crossover controlled trial in a school setting. No significant difference occurred in initial cleaning efficacy; however, following a six-hour period of use by pupils of the restroom facilities, the internal door handles wiped with Sani-Cloth CHG 2% wipes were significantly less contaminated than those with the control wipe (14% v. 32%, p = .02). Cleaning with Sani-Cloth CHG 2% wipes demonstrated significant improvements in the continuous cleanliness of restroom door handles during use with this simple and inexpensive technique.

In the Northwest Arctic Borough, the impact of climate on environmental conditions is a fact of life, and with this comes a substantial challenge to the Native Inupiat lifestyle, culture, and traditional subsistence "way of life." Like areas which are being inundated by sea level rise, these changes are affecting drinking water, sanitation and other infrastructure at the "coalface" where these impacts are most evident in the US.  See how environmental health practitioners are providing innovative solutions that promote resilience and adaptation rather than foregoing a cultural and community identity.

This session will examine the efficacy of cooperation and collaboration in environmental and public health projects. Specific examples involving cross border collaboration and cooperation between professionals from widely differing backgrounds and cultures will be explored. These lessons learned, successes, and failures will help you plan new projects and deliver existing projects more effectively.

From conception, project design, results, and lessons learned along the way, hear a case study about collaboration between federal, state and local agencies to obtain and use water quality data related to private wells while marketing the use of the data. This case study involves multiple agencies sharing data, data display using geographic information systems (GIS), and unanticipated obstacles. We learned the hard way so you don't have to.

We describe a 2016 community-wide recreational water-associated cryptosporidiosis outbreak investigation and response in Maricopa County, Arizona. Persons with a laboratory-confirmed illness were interviewed using a standardized questionnaire that assessed exposures 2 weeks before symptom onset. A convenience sample of managers and operators of chlorine-treated public aquatic facilities was surveyed regarding permanent supplemental treatment systems for Cryptosporidium. Among 437 cases identified (median age 12, range <1–75 years), 260 persons were interviewed. Public-treated recreational water was the most frequently reported exposure (177, 68%) of interviewed persons; almost 1 in 5 (43, 17%) swam when diarrhea was ongoing.

After the 2016 outbreak, managers of some facilities expressed intentions to install supplementary water treatment systems, and by May 2017, at least one large facility installed an ultraviolet light system. Strategies to prevent additional illness included community messaging, education, and targeted remediation of affected facilities on the basis of interviews. Challenges to remediation during a cryptosporidiosis outbreak in a large jurisdiction with primarily outdoor pools underscore the importance of promoting healthy swimming practices that help prevent contamination from occurring.
