Total Dissolved Solids (TDS) Trends in Water

In Canada, water contaminants that are considered to be dangerous in high amounts are listed as Maximum Acceptable Concentrations (MACs) in the Canadian Guidelines for Drinking Water Quality. However, any contaminant not considered dangerous, such as TDS, are given an aesthetic objective in the guidelines.

The Canadian guideline for TDS is less than 500 milligrams per litre (which is the same as 500 parts per million). However, as the Canadian guidelines are not enforceable, each province is free to choose whether or not it will follow the guidelines. Saskatchewan, for example, has water that naturally contains high concentrations of TDS, so the province has chosen to not follow the Canadian guideline of 500 parts per million, and to implement its own guideline of 1,500 parts per million.

How Does High TDS Get in Drinking Water?

Well water near coastal regions will have an elevated TDS level due to both seawater intrusion and deposits left by the ocean, while surface water dissolves and picks up minerals to some degree as it comes in contact with rocks, bedrock, and soils. Depending on region and geological setting, levels of TDS in water will vary.

Another common artificial source of higher TDS is road salt. When road salt is used on roads in the winter it can wash into waterways if not stored properly.

Should I Be Concerned About High TDS in Drinking Water?

Although high TDS concentration in drinking water is not harmful to your health, it can lead to poor-quality water that tastes salty or bitter, and even cause increased corrosion in plumbing and appliances, as well as faster deterioration of clothing.

These problems, as well as other potentially harmful contaminants, can be fixed by installing a whole-home water treatment system that provides better-quality water for drinking and use throughout your home. Contact your local Culligan Man today to have your water tested for TDS, and for help finding the best solution for your water needs.
