Critical Commentary
Three of Santa Ana’s zip codes, including Madison Park’s 92707, are amongst the forty California zip codes with the highest reported number of children with Blood Lead Levels (BLL) that are 4.5 mcg/dL or greater.
The table at the right shows the percentage of children under the age of six in three of Santa Ana’s zip codes that have a BLL of 4.5 mcg/dL or greater.
Blood Lead Levels in Children (cdc.gov)
The CDC indicates that no level of lead is safe. Elevated BLL can result in neurodevelopmental impairment, with no blood lead level known to be without a damaging effect. As of 2021, they use a blood lead reference value (BLRV) of 3.5 micrograms per deciliter (µg/dL) to identify children with blood lead levels that are higher than most children’s levels. The California Department of Public Health plans to adopt this reference value but is currently “working to procure the required resources” to implement the new BLRV. CDPH encourages (but does not mandate or incentivize) healthcare providers to provide retesting and follow-up for blood lead levels ≥ 3.5 mcg/dL. BLRV
