Hello all. My garden has fairly good but uneven soil. Currently I am digging a pond. About 50cm deep (1.6ft) I have found a lot of rubble and rubbish: lumps of concrete, disintegrating bin bags, old toys, plastic bottles, rotting leather, Styrofoam, bits of wood with nails sticking out. My house and the surrounding estate was built in the late 1940's and was originally council housing. It looks to me like the rubbish is from around the 80's and that for whatever reason, the previous owners just decided to cover it over. What should I do? It could be localised but I fear may affect most of the garden. Has anyone else encountered anything like this?
