A local resident named Natalia Maca, 37, often walks through the Ouse River at Huntingdon every day to detect a change in the color of the water: " I come here every day, and see it change color, when it's green, it's blue, it's not just one day, it has happened all month! '

"I called the Environment Agency and they said that I would tell the cause after the investigation but then it didn't work. It was a soap liquid but I didn't know it really. What is it, maybe someone poured a large amount of this liquid into the river and polluted the area. "
A dog was sick when he fell into the river's waters and people thought authorities should investigate industrial parks around Huntingdon to find a source of pollution.
A spokesman for Anglian Water said: "We are working with the Environment Agency to identify the source of the change in the color of the river."

"We always encourage people to inform us and unusual events so we can investigate as soon as possible, we operate 24 hours a day. However, because the river basin covers a huge area. stretching over many places, so the source location of pollution has not been determined correctly. "
While the results of the survey are not yet available, many experts believe that it is due to dyes, Dr. Dr James Ebdon - an expert on Environmental Microbiology at Brighton University responded on the page:
"I think the explanation for this phenomenon may be due to the common dye in the textile industry."
