Alongside Marston Brook, behind no 30 Arlington Drive. Large amount of aluminium cooking foil has been put through a hole in a garden fence onto the bank of the brook. (This is not on the path side but on the same side as the houses but accessible via the Marston brook footpath. Our dog jumped across and ate some of the foil, which we had to pull out of his mouth. This is very irresponsible littering - harmful to wildlife as well as allowing cooking fats to seep into the brook.
