The water supply in Australia is contaminated with low levels of lead. The cause of this contamination is believed to be brass tap fittings. In the US, the government has mandated that all plumbing fittings contain no more than 0.25 percent lead. However, the lead content of some taps has been higher. Consumers in the US and UK should take steps to reduce their lead exposure.
Some manufacturers are now making plastic faucets with virtually no lead content. Others are substituting other metals for lead in brass faucets. They may also use special coatings in the faucet. New legislation requires manufacturers to label their products as "lead-free" and to tell consumers how low their lead content is.
If you are concerned about the lead content in your water, you should have your tap tested. You can find out your tap water's lead content by contacting your local utility company or county health department. Some plumbers may also be able to help you choose a low-lead tap. However, it's not always possible to eliminate lead in your water. For this reason, it is important to invest in a quality water filter.
Lead contamination in tap water comes from the pipes in your home and the service line connecting your house to the water main. Even if the water main is made of steel or iron, it can still contain lead. Getting rid of lead in your plumbing is necessary if you want to protect your family. Lead is present in buried piping, faucets, and solder.
