Panorama on BBC One investigated the illegal dumping of untreated sewage in rivers across the country. The River Pollution Scandal aired on Monday, with the River Windrush in Witney a focus of the half hour investigation. Ashley Smith, from campaign group Windrush Against Sewage Pollution (WASP), spoke on the programme about river pollution. He told the Oxford Mail: “Getting on Panorama is a vital part in allowing people to make sensible choices and for people to get the facts rather than what the Environment Agency says. “The public has been misled and kept in the dark, and the Panorama episode has opened the lid on this.
