Since the EPA Office of Waters calculation of MCLs for Nitrate and Nitrite are based primarily upon effects in infants, is it appropriate to use tapwater screening levels based upon adult exposures?
When the exposed population at a Superfund site will not include children, then the risk-based tapwater screening level may be considered protective. If the exposed population will include children, the MCL may be considered protective. However, consultation with a risk assessor or toxicologist in the EPA Regional Office for the site in question on this matter is recommended.
