W Gdańsku staw przy szpitalu przybrał nietypowy zielony kolor, a nie jest to spowodowane zanieczyszczeniem, lecz pracami prewencyjnymi.
As specialists explain, companies servicing heating and water supply systems sometimes add a special dye to the water. The green color is most commonly used — it is easily noticeable and allows for quick detection of possible leaks
The thing is, regular water is transparent, and minor faults in pipes or tanks can go unnoticed for a long time. However, the dyed liquid immediately reveals the problem: even small leaks become visible to the naked eye
This practice is widely used in diagnosing systems and poses no danger. The dyes used are generally safe and specifically designed for such checks. After the work is completed, the water is either cleaned or gradually returns to its normal appearance
