There has been some controversy in the area recently about building new homes on contaminated land. This got me thinking. I've recently filled some raised beds for growing veg in with topsoil from the local builders merchants. It was sieved and that's all I know about it. Should I be worried about heavy metals etc?
I guess even if I was growing veg straight into the ground I wouldnt know what contaminants were already in there. Am I just being dramatic?
