What is the action level (AL) for lead in school drinking water?
EPA recommends that action be taken at a specific outlet when the lead concentration is over 20 parts per billion (ppb). (Note: this is different from the 15 ppb action level required for public water systems). For an explanation, see an excerpt from the preamble to the Lead and Copper Final Rule at http://water.epa.gov/drink/info/lead/excerptfrom58.cfm. Also, 40 ppb of lead can indicate imminent and substantial endangerment to the health of children and pregnant women, based on toxicological studies focused on young children.
