The pollution of water bodies in Bradford in West Yorkshire is the responsibility of the dishwashers of 200 Asian restaurants in the city.
The underground rivers that flow beneath Bradford turned yellow because of turmeric and other spices for curry, which are drained into it. Now all these polluted waters flow into the Aire river, which caused anxiety and protests among the local population.
The problem that arose was described in the Friends of Bradford Beck annual report, which led the Environment Agency to conduct its own investigation. Rob Hellawell stated that numerous curry restaurants did not violate any laws and did not know about the effect of spices on local water bodies.
He explained: "Even in the times of the Industrial Revolution, factories poured their waste into the water. Later, numerous bends were built, and the dishwasher systems of restaurants are connected not to the sewage system, but to these drainage systems. The builders see the drainage system and connect to it, not realizing what in fact it is."
Rob Hellawell said that the restaurants took appropriate measures when it became aware of the problem, which has already allowed some to improve the quality of water.
In Bradford there are 200 Indian and Asian restaurants, and the city has already been awarded the title of "British Curry Capital" six times. Such large Asian population is explained by the fact that during the Industrial Revolution the textile industry flourished in the city and Bradford needed labor, which means there was a great need for immigrants.
