How to Remove Lead from Your Drinking Water

Water pouring into a glass.

Drinking enough water every day is essential to your best health.

Since it’s recommended that adults drink at least eight glasses of water a day, shouldn’t we do our best to ensure that this essential fluid is of the best quality? Tap water, although quite regulated and seemingly clean in developed countries, can still have impurities lingering in it. One of the most common is lead. Many studies have shown that consuming water with traces of lead in it can be harmful to your health. Luckily, there are things that you can do to ensure that your drinking water is clean and free of harmful contaminants.

The Truth About Lead in Drinking Water

Regular consumption of lead in drinking water can be harmful to the health of you and your family over long periods of time. Lead is most often found in homes that were built before the 1980’s. Even with updated plumbing, lead can still make its way into your drinking water.

Information from the Centers for Disease Control and Prevention (CDC) shows that exposure to lead can result in behaviour problems and learning disabilities in young children and other various health problems for adults.[i]

According to the United States Environmental Protection Agency (EPA), there is no known safe level of lead in a child’s blood. In fact, lead is harmful to health, especially for children. The EPA has actually set the maximum contaminant level goal for lead found in drinking water to zero. This is simply because lead is a toxic metal, one that can be harmful to human health, at even the smallest levels of exposure.

As mentioned above, exposure to lead can be harmful to adults as well. Pregnant women risk reduced growth of the fetus and premature birth, while all other adults who are exposed can suffer from cardiovascular effects, increased blood pressure, incidence of hypertension, decreased kidney function, and reproductive problems.[ii]

Testing Your Water for Lead

Water Depot carries home use water test kits, which are good for detecting lead in water. They can be purchased at any Water Depot location.

Another effective way to ensure that lead isn’t in your tap water is to have it professionally tested. Water Depot offers free in-home water testing, so you can ensure your best health at no charge at all. Our experts want to help ensure that you and your family are healthy and safe.

Although the home use water test kits are effective, the free water test performed by highly-trained Water Depot technicians has proven to be more thorough and accurate in the past.

If our water technicians suspect water problems that are not easily treated by standard water equipment, they can send out the sample to an independent lab, where a more accurate detection of bacteria and other contaminants will take place.

If the results do come back positive for lead, or other various contaminants, we can identify them accurately and advise you on the best treatment method. For lead in drinking water, we highly recommend a Reverse Osmosis System.

How to Remove Lead from Tap Water

If you suspect that your tap water is contaminated by lead, leave the water to run for about 10 to 30 seconds at the coldest temperature before you use the water. This can be an effective method to reduce traces of lead from your water, especially if the tap hasn’t been used for six or more hours. You should also aim to only use cold water from the tap, as hot water is more likely to have traces of lead in it.

Of course, this is only a temporary suggestion. You should aim to schedule an in-home water test as soon as possible, to ensure that the tap water in your home is safe. If the test does come back positive for lead, installing a lead-removing water purification system, such as a Reverse Osmosis System, can be an effective solution to the problem.

For more information about our water purification systems for sale, contact the experts at your local Water Depot location. Water Depot has showrooms in Hamilton, Guelph, Kitchener, Brantford, Cambridge, and throughout the GTA.
