It also is the location of an old fire pit. We have been picking up trash on our property for two years & have a feeling the old owners may have burnt toxic things here (pressure treated wood, trash, etc.). For that reason, we would like to plant super-plants that will pull up those toxin from the soil.
I would try to get some mushroom slurries poured into the soil where you feel contamination may be lurking, the mycelium will work with the other toxin accumulators (sunflower, daikon, crimson clover are good TA functioning plants as well as many others but these three play nice together).
The more, different fungi you can get inoculated into the suspect soil, the better, most mycelium don't kill off each other, they might make some species move away from them but they generally seem to be ok as long as there is enough space between the species.
Of course, if you are using found mushrooms or not worth eating mushrooms to make the slurries with, it will be more a matter of use what you have, over which ones play nice together.
I do have some other ideas Mj, should you want more on getting toxins out of soils.
