Bitumen treated wall in vegetable planter?

Hi, I have built a concrete planter and one wall of it is shared with the house wall (made of stone and plaster). Concerned about moisture seeping into the house I painted several layers of bitumen onto the wall below soil surface (1,5 gallon). Would it be safe to grow vegetables in that planter?
