It has been well documented that urban residential areas potentially have high levels of heavy metals particularly lead (Pb) in their soils.   Additionally, other carcinogenic toxins may be present in the soil depending on the historical use of the property or if the structure was destroyed by fire. 

The Ag agent has sampled many of these residential and agriculture sites to determine if the soils were suitable for food production, and safe for children. Recently soil sample test results indicated extremely high levels of lead in the garden soil where vegetables were being harvested. The Ag agent notified the home owner of the potential human health risk, recommending additional soil and plant tissue testing analysis. Educational publication references on the potential health effects of exposure to heavy metals was provided to the homeowner with an assisted process for mitigation of the carcinogenic toxins. 

Other residents have indicated concern and interest regarding an analysis of their particular lawn or garden soil.  The Ag agent contacted Louisville Metro partners for assistance in convening neighbor meetings and the sharing of information in newsletters. 

More residents rely on the Extension Service for current information on soil quality for gardens, crops and lawns, while gaining important knowledge regarding soil carcinogens and safety. These outcomes have resulted Ag agents, through the Urban Extension Institute Fellows program, conducting extensive research in Louisville’s “Food Desert” neighborhoods, where many vacant lots could potentially be in use for food production.
