People on social media have been left puzzled since a picture surfaced online depicting a Leeds stream that had turned bright green.
The peculiar photo was taken by Emma Harland and shared by her husband Mark Harland (@HarlandMark) on Twitter.
Mark Harland posted the image early yesterday (Tuesday 25 April) morning and captioned the image: “Hi folks. Any idea what the green colour in the stream is?”
The local community were left puzzled and no one seemed to know what exactly had occurred or why.
Harland tagged The Friends of Gledhow Valley Woods in the post, a group dedicated to the conservation and interests of Gledhow Valley, including pollution of the beck.
The group were unfortunately unable to confirm what had happened and concerns of pollution arose.
The group contacted Yorkshire Water to investigate the matter.
A Yorkshire Water technician was promptly sent out to assess the incident and whether further action needed to be taken.
Yorkshire Water confirmed on Twitter at 2pm that it was a green dye in the Gledhow Beck.
The dye was used to check to the direction and rate of water flow of the nearby drainage system in the area.
The dyes commonly used for this purpose are non-toxic, biodegradable, safe for the environment and EDF approved.
A similar green dye was released into a river in Chicago earlier this year in celebration of Saint Patrick’s Day.
100lbs of dye fluid were reportedly used for the occasion and the effects lasted for an entire week.
The dye will eventually degrade and leave Gledhow Beck of its own accord without any further human intervention.
Yorkshire Water therefore deemed that no one should panic and that no further action is required in regards to the incident.
The mystery of the green Gledhow Beck has officially been solved.
