Near Roadway information for Tom Grahame





Tom Grahame asked whether we had information regarding lead
concentrations near roadways (such as gradient studies).  Deirdre
identified 2 sections of the Criteria document and 1 appendix to the
Lead Risk Assessment that deal with lead in outdoor soil and dust near
roadways.  These are:

Criteria Document

Chapter 2, section 2.3.3 "Resuspension of Lead Containing Dust and Soil"

Chapter 3, section 3.2  "Exposure:  Soil and Dust"

Risk Assessment

Appendix F:  "Lead in Outdoor Soil and Dust near Roadways"-- this
appendix includes a table listing key studies and summarizing their
design/findings in terms of lead concentrations

Perhaps we could send this to Heidi to forward on to Tom, along with the
links to CD, Staff Paper, and Risk Assessment?
