For most Canadians, turning on the kitchen tap is part of an ordinary daily routine. But if you live in an older home, especially one built before the mid-1970s, you’ve probably wondered whether lead could be getting into your drinking water.<\/p>\n

The good news is that lead is usually not found in high amounts in treated municipal water leaving Canadian treatment plants<\/span>. In many cases, the concern begins after the water enters the distribution system or your home’s plumbing. Older service lines, lead solder and some brass fixtures can allow small amounts of lead exposure Canada<\/a><\/strong> to enter tap water, particularly when water has been sitting in the pipes for several hours.<\/p>\n

The risk isn’t the same for every home, but understanding where lead comes from and how to reduce exposure can help you make informed decisions for your family.<\/p>\n

What Is Lead and Why Is It a Concern?<\/h2>\n

Lead is a naturally occurring metal that has been widely used in plumbing, paints, gasoline and other products over many decades. While many of those uses have been restricted in Canada, older buildings can still contain plumbing materials that contribute lead to drinking water.<\/p>\n

Health Canada explains that lead exposure can affect people of all ages, but there is no identified threshold below which lead is completely free of health effects<\/span>, which is why exposure should be kept as low as reasonably achievable.<\/p>\n

How Does Lead Get Into Drinking Water?<\/h2>\n

Contrary to what many people assume, lead usually does not<\/span> come from lakes, rivers or municipal treatment plants.<\/p>\n

Instead, it most often enters drinking water through older plumbing materials.<\/p>\n
