This is low compared to the legal limit of 15 parts per billion.

Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.

There is no safe level of lead for humans.

The good news is that 99.99% of the lead can be filtered out.
