  • Can you filter lead out of water?

    Posted by ,

    Water filters are the most effective way to remove lead from drinking water. Advanced carbon filters can purify your water by removing most contaminants, including lead in water, while leaving other naturally occurring minerals in the supply. If you’re looking for a higher level of filtration, then a water dispenser could be right for you.

    Quick Facts

    • Lead contamination can occur due to corrosion of old lead pipes that supply drinking water to buildings.
    • Although lead piping is rare across Australia, some pipes are fitted with lead-based solders.
    • Consuming levels of lead above 0.01 mg/litre can have a negative impact on your health.
    • One test found lead in Melbourne water at over 10x the Australian guidelines.
    • If you find lead in your drinking water, you should contact your local authority as soon as possible for whom you can find details at the end of this article.

    Reasons why you may find lead in drinking water

    Australia has relatively few buildings where lead piping is installed, as copper began to replace lead piping throughout the 1930s. Problems associated with lead contamination in drinking water do still occur however, where there is corrosion on pipes that do contain lead in the piping itself or due to the fact that some pipes are fitted with lead based solders. This can be a problem particularly where water has been held within a space over a course of several hours. For this reason, most instances of this type of contamination occur during morning hours, or after a building has sat unused for a time period, such as business offices over a weekend.

    Lead and your health

    The Australian Drinking Water Guidelines have defined the ‘safe’ level of lead fit for consumption as 0.01 mg per litre (this figure has been lowered from the previous recommendation of 0.05 mg per litre).

    Despite these guidelines there is no national or local government enforced monitoring of lead contamination within public water supplies. This is really worrying if you consider that consumption of lead at levels just above the recommended amount has been linked to problems such as the slowing of mental and physical development in young children. In recent years, lead has been found in the water supply of major cities in Australia, e.g. in Brisbane and Melbourne.

    Even more concerning is that If you’re to consume lead at higher levels over a long period of time it is known to cause significant damage to the brain, red blood cells, and kidneys and even with only short term exposure, it can lead to elevated blood pressure levels.

    Advice on how to remove lead from drinking water

    “Implement a pilot program for testing lead in first flush drinking water, rainwater tanks and drinking fountains; conduct education programs to inform home handy persons of the dangers in using lead solder in plumbing and review drinking water guidelines for lead in context of an overall lead reduction strategy".

    The problem with this contaminant is that you can’t see, taste, or smell lead within your water. Indicators you can look out for include whether your building is using an old lead pipe system. If you have reason to believe this is the case at home or at work then you should contact your water supplier or local authority immediately. You can find the details of local governmental bodies that can help below.
