The following link will take you to an article written in the Guardian Environment Network. The article summarises a piece of work carried out to assess the contribution that former landfills have made to pollutant concentrations in the nearby River Thames.

Over a five mile reach of the Thames at Port Meadow, the amount of ammonium delivered to the river attributed to landfill leachate is understood to be in the order of 27.5 tonnes, increasing concentrations of ammonium by approximately 40% in that stretch of water.
