We are cautious about drinking tap water while visiting developing countries. Yet at home with our private water supplies, we can sometimes be a little lax about applying the same care and consideration. Just because the water tastes okay does not necessarily mean it’s safe to drink.
Nolan Shaheen is Director of Groundwater Management for the Saskatchewan Watershed Authority. “Anyone with a private water supply that is being used as a drinking water source should have the water tested for health-related parameters such as nitrates, fecal coliforms, heavy metals such as arsenic, uranium and selenium, and major ions like sulphates, potassium, bicarbonates, calcium, magnesium, sodium and chlorides. Water should also be tested for hardness, especially if it is used for agricultural purposes. For instance, if you use herbicides like glyphosates, the hardness of the water can affect performance.”
“Many heavy metals occur naturally, and toxicity will vary according to concentrations and quantity consumed,” Shaheen explains. “We encourage you to consult health professionals to find out more about how these levels relate to the Provincial Drinking Water Guidelines, which are set to protect human health. As you can imagine, high concentrations could have some health-related effects. Consumers who draw water from wells that yield higher concentrations might want to consider drinking bottled water and using their well water for purposes other than drinking.”
Nitrates are another parameter that requires care and attention. Although they can occur naturally in the environment, the presence of nitrates is often associated with improper management of sewage or over-application of fertilizers.
Bacteriological testing should be carried out, as well as testing for iron and manganese, two metals that are commonly found in higher concentrations in Saskatchewan water supplies.
“Some parameters will only affect taste and colour, as in the case of iron which will stain laundry and impart a metallic taste to the water, but it will not harm you. That is what we refer to as more of an aesthetic consideration. In the case of other parameters, consequences can be much more serious,” says Shaheen.
Private water supplies’ stewards have a few options for testing. They can access one of a number of private labs in the province. There is a provincial health laboratory in Regina. The Saskatchewan Research Council has its own lab in Saskatoon. Any of Saskatchewan’s Health Districts will be able to provide a hand-sized water sample container.
“If you collect your own sample, due care and attention should be given to preventing sample contamination,” says Shaheen. “For instance, touching the inside of the container with your fingers could ruin the bacteriological component of the test.”
And remember, most water can be treated, and there are always a number of options to address unsafe water challenges. The first step, of course, is to be aware of the water’s quality.
