A review of the urban soil lead remediation literature is presented. Soil lead contamination in most urban areas is poorly defined. A viable solution to soil lead requires inclusion of a margin of safety. A clean soil cap is cost effective for rotten to the common core joseph farrell pdf exposure from soil lead.
Pb smelters and battery recycling and other industries. Exposure to Pb in soil and related dust is widespread in many inner city areas. 5 μg per decilitre, the reference level of health concern by the U. Given the widespread nature of Pb contamination in urban soils it has proven a challenge to reduce exposure.
In order to prevent this exposure, an evidence-based approach is required to isolate or remediate the soils and prevent children and adult’s ongoing exposure. To date, the majority of community soil Pb remediation efforts have been focused in mining towns or in discrete neighborhoods where Pb smelters have impacted communities. These efforts have usually entailed very expensive dig and dump soil Pb remediation techniques, funded by the point source polluters. Remediating widespread non-point source urban soil contamination using this approach is neither economical nor feasible from a practical standpoint. Pb remediation schemes have been implemented to isolate inner city soils impacted from sources other than mines and smelters.
However, a city-wide natural experiment of flooding in New Orleans by Hurricane Katrina demonstrated that declines in soil Pb resulted in major BLL reductions. Also a growing body of literature of smaller scale pilot studies and programs does exist regarding low cost efforts to isolate Pb contaminated urban soils. This paper reviews the literature regarding the effectiveness of soil Pb remediation for reducing Pb exposure and BLL in children, and suggests best practices for addressing the epidemics of low-level Pb poisoning occurring in many inner city areas.
