Luminous green water has puzzled workers at a Dundee industrial estate.
Following a shower of rain workers at different businesses noticed bright green water in puddles and in raindrops on their cars.
The North Tay estate on Balfield road is the site of the old RGL contracts building, and during the demolition barrels of Flourescein, a chemical dye used by welders and plumbers and also in medical capacities, were opened.
The dye is a red or brown power and during windy conditions of the last few days blew out of the site.
Upon contact with water the chemical turns luminous green, allowing it to work as a tracer.
It is not considered dangerous, but can cause nausea and anaphylactic shock in some.
Jacki Millar said: “Nobody has been here at all to tell us about whether it is safe or any precautions we should take.”
Phil Wallace, who works in the area said: “All we know is that SEPA have been down and analysed it and found it is not toxic and not harmful.”
Workers at the site, who did not wish to be named, said that barrels of the chemical had been in the loft space of the building and were removed prior to demolition.
Green water has been visible on the site for over a week, they said, but this was the first time that the unusual colour had seeped outside of the site.
The containers were ruptured and following windy conditions the power spread outside of the site.
A spokesperson from the Scottish Environment Protection Agency (SEPA), said: “SEPA officers did inspect a premises on Balfield Road last week following a complaint of green liquid flowing out of a demolition site.
“On inspection, the green liquid was identified as a tracing dye commonly used in drains which had accidentally been displaced from container on the site. While the dye does colour water bright green, SEPA officers are satisfied that there is no impact on the environment.”
Coldside councillor Jimmy Black said: “I can’t stress enough how important it is for businesses to be responsible for the disposal of chemicals.
“If used improperly, these agents can get into the water supply, they can cause damage to humans and wildlife.
“I will be asking environment officers from the council to do their best, and if there is negligence to pursue those responsible.”
A Dundee City Council spokesperson said: “Council officers have visited the site and will be working with SEPA to investigate the situation.”
