Why is the maximum contaminant level MCL for nitrate set by the EPA as 10.0 ppm?
The MCLG for nitrates has been set at 10 parts per million (ppm), and for nitrites at 1 ppm, because EPA believes this level of protection would not cause any of the potential health problems described below. Based on this MCLG, EPA has set an enforceable standard called a Maximum Contaminant Level (MCL).
Which states have MCL for PFAS?
Notably, in 2018, New Jersey became the first state to adopt an MCL for PFAS, setting a limit of 13 ppt for PFNA—another chemical in the PFAS family. Massachusetts, Michigan, New Hampshire, New York and Vermont also have established safe levels for PFAS in drinking water.

Why is there no MCL for lead?
These non-enforceable health goals, based solely on possible health risks, are called maximum contaminant level goals (MCLGs). EPA has set the maximum contaminant level goal for lead in drinking water at zero because lead is a toxic metal that can be harmful to human health even at low exposure levels.
