OVC Researcher Works With Local Company on Well-Water Study

Sampling groundwater qualityA One Health researcher at the University of Guelph’s Ontario Veterinary College (OVC) is leading a US$3.6-million study focused on reducing preventable waterborne disease in residential drinking well water.

The study is funded by the National Institutes of Health in the United States.

Dr. Heather Murphy, who recently joined OVC’s Department of Pathobiology as a Canada Research Chair in One Health, will explore illness-causing microbes in residential well water in southeastern Pennsylvania, the impacts on families with young children and the effectiveness of home water treatment systems. The study is called the Wells and Enteric disease Transmission (WET) Trial.

Murphy heads up the Water, Health and Applied Microbiology Laboratory (WHAM Lab), which is split between OVC and the Department of Epidemiology and Biostatistics in the College of Public Health at Temple University in Philadelphia, Pennsylvania where the study is taking place.

Dr. Heather Murphy, Ontario Veterinary College, University of Guelph“Environmental regulations protect public drinking water systems, but public safeguards don’t apply to privately owned wells, where water quality testing is the responsibility of individual owners, and the prevalence of waterborne diseases can threaten residents’ health,” said Murphy.

Private wells are also not limited to rural areas—they are often used by families in suburban and rural subdivisions. This is not only a challenge in the U.S. but is a problem in Canada and many other countries around the world, adds Murphy.

Earlier in her career, as a research fellow with the Public Health Agency of Canada, a burden of waterborne disease estimate Murphy published showed that private wells are a problem in Canada, information that encouraged her to pursue further research in this area.

As part of the study, Trojan Technologies, a London-based company is donating more than 900 home UV water treatment systems to households participating in the study, valued at $1,000 per installation. VIQUA, Trojan’s domestic water system brand manufactured locally in Guelph, Ontario, will be producing and delivering the equipment in support of Murphy’s study. Trojan Technologies equipment is used around the world in drinking water and wastewater applications, as a barrier against potentially harmful microbial contaminants and in the remediation of pollutants such as 1,4-Dioxane.

Throughout the study, researchers will monitor how often the children get sick, said Murphy. All participants will be required to respond to weekly text messages and occasional questionnaires. Some will be asked to submit stool, saliva and water samples to be tested for specific microbes.

“We’re hoping to better understand if drinking well water can cause illnesses in children that can include diarrhea, fever and even respiratory problems. We want to know if treating well water can prevent these illnesses.”
