Answer: There is certainly a possibility of this happening, but you would need to have the plants and soil analyzed to see if it is so. To be on the safe side, I would strongly suggest growing edible crops elsewhere. If you have a well you might also look into having your water tested -- consult with the testing agency as to which tests to run but they would include heavy metals for starters since you found batteries and car parts. Your county extension (424-9485) may have some insights on this as well as suggestions of who to contact or how to verify whether or not it really is a problem in need of remediation.
