On Friday 15 April Woodbridge Festival launched its summer programme at the Sun Deck music nights by the river, featuring a Light Art exhibition, highlighting river pollution, projected onto the iconic 300 year old Tide Mill landmark in Woodbridge.

Resident DJ, and co-founder of Woodbridge festival, Ben Osborne, provided the music while VJ Jim Horsfield projected local artist Ruth Leach’s exhibition, featuring local people she associates with life on the river.

The event highlighted pollution levels in the river, recently revealed in a survey by Woodbridge Town Council and University of Suffolk. Councillor Eamonn O'Nolan says three out of 13 sites they tested along the Deben were "significantly" below the Government's pollution standards.

Ruth Leach’s pictures had been exposed to river water over several weeks as part of the artistic process. This caused a decay in the photographs, which is captured in the projected images.

The event pre-figured this weekend’s nationwide activity highlighting river pollution, organised by Surfers Against Sewage and wild swimmers - Ben Osborne will also DJ at a protest swim being organised by Manningtree Mermaids Against Sewage on Saturday 23 April.

As well as presenting international live music acts and DJs, Woodbridge Festival of Art and Music has an active environmental area and regularly runs schools and workshops on the environment.

The pictures include an image of Dan Tarrant-Willis, the miller at the iconic Woodbridge Tide Mill.
