are you aware of any studies that determined how far from house foundations which are treated annually for termites one can safely plant vegetables, i.e., how far (horizontally) from the spray/granule contact area do those chemicals migrate into the soil?

We do not know of a study. First you would need to know the name of the chemical which was used in the treatment. You may need to contact the pest control company which did it. They have to keep good records. Then you can find the Material Safety Data Sheet online for that chemical and/or contact the National Pesticide Information Center with your questions: 1-800-858-7378.
