Queen's University Belfast has won a top award in the national campaign to find Britain's greenest companies, councils and communities.
The University won a Green Apple Environment Award for the arsenic-removal water cleansing project, which was carried out by the School of Planning, Architecture and Civil Engineering.
The School competed against more than 500 nominations to win this award in the international category. The award was for Dr Bhaskar Sen Gupta and his team's work in developing a method to remove arsenic from ground water without the use of chemicals, in the world's first low-cost arsenic removal plant in India.
Dr Sen Gupta said: "I am delighted we have been awarded this UK Industry Award as it is a great recognition for the work we have been carrying out into the removal of arsenic from groundwater without using chemicals.
"It recognises the team's hard work in tackling the world's worst case of ongoing mass poisoning. This solution overcomes arsenic contamination of groundwater and improves the quality of life in rural communities."
As a result of this success the University has been invited to have their winning paper published in The Green Book, the leading international work of reference on environmental best practice, so that others around the world can follow their example and learn from their experience.
The Green Apple Award recognises, rewards and promotes environmental best practice around the world.
The University will also be considered for the European Business Awards for the Environment.
