The study aims to eliminate the hormones and chemical products contained in drinking water, which can cause certain health problems, like cancer, to develop. “The water that we drink comes from someone else’s waste water,” explains Professor Jackson.
In order to evaluate the quality of the water coming from the water treatment plant of Calgary, the team of researchers will conduct their tests in canals that recreate the ecosystem of the Bow River, the metropolis’ source of drinking water.
Next spring, fish will be introduced into the canals, as well as different medications. This is in order to see the effect of chemical products on the fish’s genetic code. “Genes that are activated or deactivated, or changes in the population of fish would indicate contaminants,” explains Jackson. The results will then be applied to humans.
Jackson explains that certain particles are so tiny that they sneak through the different water treatment tanks and end up in the area’s drinking water. The effects of chemical products have already been observed in humans. “A lower rate of fertility, as well as an increase in cancers, has been observed in people living in industrialized countries,” he says.
The scientist hopes, through the study, to be able to develop technologies for eliminating these carcinogens from waste water.
