If you're looking for a low lead faucet, there are several options to choose from. One way to ensure that your faucet is low in lead is to purchase one certified by the NSF, a nonprofit organization that develops and tests standards. Among its many goals is the protection of human health and the environment. You can learn more about Annex G and how you can make sure your faucet meets this standard by visiting the NSF website.
While public water supplies are free of lead, faucets made from brass alloys can still contain traces of the metal. This is why it's a good idea to get your water tested. If you're concerned about lead in your water, contact your county health department or drinking water utility. They'll do a free test for you.
Recent state legislation is limiting the amount of lead allowed in faucets and other plumbing fixtures. This legislation affects products sold in Vermont and California. However, it does not change the amount of lead that leaks into water. The legislation also does not address the actual make-up of drinking water. So, you should consider purchasing a low lead faucet, if possible.
