The maximum concentration set by the U.S. Environmental Protection Agency for lead in drinking water is 15 ppb.

-What is this concentration in milligrams per liter?
-How many liters of water contaminated at this maximum level must you drink to consume 1.0 μg of lead?
Can someone just guide me through the steps for this!!! Thanks(:,

1 part per billion is roughly 1 microgram/Liter, which is equivalent to 1 milligram per cubic meter. From there to convert 15ppb to ug is a direct shift. If the concentration is 15ppb and a Liter is consumed, a microgram of lead has been consumed.
