μg/L
microgram per liter
DensityConcentrationexact by definition
The microgram per litre is exactly 10⁻⁶ kilograms per cubic metre, and equal to one part per billion in dilute water. Lead, arsenic, trihalomethanes and most trace organics in drinking water are regulated at this level: the lead action level in North America is 10 to 15 μg/L.

As a unit of concentration
The microgram per litre is 10⁻⁷ percent, equal to one part per billion in dilute water. Trace metals, pesticides and disinfection by-products in drinking water are regulated here: the lead action level is 15 μg/L and the arsenic limit 10 μg/L.
