Did you know that your household water supply travels miles to reach your tap? That said, we know water meets lots of lead along the way. Here are the different channels:
- Lead Service Lines that are used to connect the water main to individual houses are a major source of contamination. Two to five million of these pipes according to reports , exist in the US mainly in areas where homes were built before 1986. They haven’t been removed because replacing them would cost as much as $14 billion.
- Lead Soldering is another significant source. Until about 1988, lead was used to connect all types of metal water pipes to one another.
- Brass Fixtures (this includes faucets, valves and water meters) may contain up to 8% lead even if the words “lead free” appear on the package. Should you purchase these type of plumbing, be sure it is marked “no lead added”.
