Letter Health Consultation: Review of Soil Gas Data Collected in 2013, Lee's Lane Landfill Site, Louisville, Jefferson County, Kentucky, July 28, 2014.

摘要

This health consultation is in response to a request for our review of soil gas data collected in 2013 from the Lees Lane Landfill site. Various volatile organic compounds were found, mostly in deeper wells, in an area where subsurface contaminant migration to homes in the nearby Riverside Gardens subdivision is possible. The contaminant concentrations in the soil gas are high enough and may be close enough to the homes to warrant further investigation under both EPA and ATSDR current guidance related to vapor intrusion. Seasonal variations may increase the potential of vapor intrusion into the homes, but there is only limited data available to evaluate this possibility.
