Happiness said:There are many ways to remediate toxic substances besides removal of the substances. One of the most common ways is "protect in place" which in the case of land, means burying the toxic substances under clean dirt. Protect in place doesn't mean the cleanup was not "done well." There are situations where the process of removal could release toxins into the environment and cause a bigger mess. It could be that the "don't eat fruit" warning relates to fear that the roots of the trees may tap down to something potentially harmful.zubs said:If the cleanup was done so well, why does the contract need to stipulate "DO NOT EAT FRUIT from backyard, etc."?
Soil readings are "instantaneous" equivalents whereas fruit accumulates toxic (and non-toxic) compounds. The harmful stuff is always there but in amounts that are deemed acceptable by current environmental regulation.
