Predicting coliform presence in private wells as a function of well characteristics, parcel size and leachfield soil rating.

Public water systems must be tested frequently for coliform bacteria to determine whether other pathogens may be present, yet no testing or disinfection is required for private wells. In this paper, we identify whether well age, type of well, well depth, parcel size, and soil ratings for a leachfield can predict the probability of detecting coliform bacteria in private wells using a multivariate logistic regression model. Samples from 1163 wells were analyzed for the presence of coliform bacteria between October 2017 and October 2019 across Gaston County, North Carolina, USA.

Effect of a manager training and certification program on food safety and hygiene in food service operations.

Food safety is an important public health issue in the U.S. Eating at restaurants and other food service facilities increasingly has been associated with food borne disease outbreaks.

The effectiveness of education as a tool to manage onsite septic systems.

Onsite septic systems meet the needs of homes that lack access to municipal services. Although they present an important source of contamination to receiving waters, they are given relatively little regulatory attention. Proper maintenance and use of onsite systems is simple and inexpensive, and can substantially decrease risk of system failure.

Skills, knowledge, and abilities of graduates from accredited environmental health science and protection undergraduate programs.

The National Environmental Health Science and Protection Accreditation Council (EHAC) has the mission of enhancing the education and training of students who intend to become environmental health science and protection practitioners/professionals. Academic programs that demonstrate compliance with EHAC guidelines can become accredited with the expectation that graduates of accredited programs will have the knowledge, skills, and abilities needed for professional success. The study reported on here reviewed these guidelines in light of results from a survey of program graduates and their supervisors.
