California Public Health Goals Data

Health Risk Category: Developmental neurotoxicity (neurobehavioral effects), carcinogenicity, cardiovascular toxicity (high blood pressure)
Cancer Risk at PHG: 0.00000003
MCL value (mg/L): 0.015
Cancer Risk at MCL: 0.000002
Last PHG Revision : 2009
California PHG Comments:

CA MCL reflects the action level, measured at the tap. The calculated cancer PHG is 0.006 mg/L. The non-carcinogenic PHG is more sensitive level and thus used as the PHG for lead.
