 The waste has been capped with around 1.5 metres of top soil and possibly clay beneath this but, at parts, there is exposed soil which has a red colour to it and has been given the name "Burgy Mud".This red colouring is one of the main characteristics of the Burgies.Although it has been capped, there is still a lot of run off of an unknown composition probably due to water soaking in and absorbing the chemicals within and then seeping out at the bottom.
