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. |
