Does Burien have Lead contamination?
Yes, Burien (and the greater Seattle area) has lead in its water. The most recent Lead samples collected in 2019 showed concentrations up to 5.5 parts per billion.
The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.
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.
