Run the water through a distiller. Water distillers work by heating water to boiling and then collecting the steam that is released.
The metals that filled the water do not evaporate with the steam but instead collect on the bottom of the distiller, leaving the collected steam clean and clear. While many water plants use distillers, there are also versions available for home use.
Remove the heavy metals with a filtration system. Many water filtration systems are available on the market.
Seek a system that specifically says that it removes heavy metals. Filtration systems that perform this task do so by running water through filters that contain materials attractive to metals.
If your water filtration system is rated for the removal of heavy metals, something that would be indicated on the filtration system package, it will take out a large percentage of the heavy metals in your water.
Install a reverse osmosis system, attaching it to your water system. If you want pure and heavy-metal-free water to flow freely from your tap, install a reverse osmosis system.
This system removes heavy metals by passing water through a membrane and draining out the additives, including heavy metals, that cannot pass through.
