Dyed water surfaced near the CATL battery plant in Debrecen, in eastern Hungary, on Tuesday, the mayor’s office said in a statement, adding that experts were investigating the situation.
The water was used in a pressure test earlier in the day, dyed green to make it easier to determine leakage, the statement said. After the test, the dyed water was released into the sewage system, where it surfaced again due to a blocked pipe.
According to information received from CATL leadership, the company conducting the pressure test and the local waterworks, the water is not contaminated, the mayor’s office said.
The pollution has been localised and municipality employees will ensure it does not find its way to natural waters, the statement said. The water’s lab analysis is also under way, it added.
