If you are concerned about lead in your tap water, there are ways to minimize the exposure. For instance, you can install a point-of-use filter, which can remove many contaminants.
You can also consider installing a certified filter, which can be added to your entire house system. However, this may not be the most cost-effective option for long-term use.
Fortunately, the federal government has made it easier to eliminate lead in your drinking water. It has outlined standards for the minimum amount of lead that is allowed in plumbing fixtures. The Safe Drinking Water Act defines a maximum of 8 percent lead in pipe and fittings.
The Reduction of Lead in Drinking Water Act further limits the permissible levels of lead in drinking water. This law is effective in January 2014.
Specifically, it requires that "lead free" faucets meet new requirements. Currently, brass taps marketed as "lead free" may contain up to 4.5% lead.
While this may not be an issue for you, it is a problem for people with lead poisoning. When using lead-contaminated tap water, you should flush it for at least two minutes before consuming it.
Lead is a heavy metal that is most easily absorbed into the body through the lungs. It also impairs the development of the brain. Those who are pregnant, or breastfeeding, should filter lead from the tap water.
In addition to purchasing a lead free tap, you should also check with your local water authority to determine whether your drinking water is lead contaminated. Most source waters naturally have very low lead levels.
