If you have concerns about a wide range of contaminants in your drinking water such as chemicals and heavy metals like lead, you may want to consider a reverse osmosis water filtration system.

The reverse-osmosis membrane acts like an very fine filter to create drinkable water contaminated water. The membrane has microscopic openings that allow water molecules, but not larger compounds, to pass through.

The system is usually located beneath the kitchen sink since it is used to treat water for drinking and cooking purposes. Reverse-Osmosis systems consist of the pre-filter, RO membrane unit, a pressurized storage tank for the treated water, a post-filter and a separate delivery tap for the treated water supply.

The reverse osmosis water filters do a very good job but can get pricey, so it is a good idea to shop around and compare.
