There are results of research on oil-derivative pollution at the Ołowianka pumping station in Gdańsk. According to VIEP, the results indicate 90 percent compliance with lubricating oils and 85 percent compliance with insoluble salts of higher fatty acids. The prosecutor’s office launched an investigation into the matter.
Recall that the events took place on January 5 in the evening. Employees of the Gdańskie Wodociągi company revealed an influx of a chemical substance of unknown origin in the Ołowianka sewage pumping station in Gdańsk, in the form of a slurry floating on the surface of sewage.
– Thanks to the efficient action of employees of Gdańskie Wodociągi, the substance was pumped out and did not flow further towards the Wschód Treatment Plant – reported Magdalena Rusakiewicz, spokesperson for Gdańskie Wodociągi.
The Voivodship Inspectorate of the Environment was immediately informed about the case, which took samples of the substance for testing. Nearly 15 tons of pollutants were pumped out and transported to an entity authorized to process this type of waste. According to preliminary findings, the illegal drop could have taken place in the districts of Zaspa or Wrzeszcz Dolny.
There are test results
As the Provincial Inspectorate for Environmental Protection in Gdańsk informed in a Wednesday’s announcement, the Central Research Laboratory of CIEP, branch in Gdańsk, on Wednesday provided the results of testing a sample of a substance taken from the collector of the sewage pumping station.
– The sample was tested to identify the origin and type of waste. According to the report received, the test results do not give a clear answer as to the possible origin and type of the tested substance, however, they show about 90 percent. compatibility with lubricating oils and 85% compatibility with insoluble salts of higher fatty acids.
As emphasized by VIEP, the report shows that the tested substance is “a mixture consisting of long-chain aliphatic hydrocarbons and additional impurities originally from waste as well as from the sewage system”.
The investigation continues
The Prosecutor’s Office has already received two notifications from the Provincial Inspectorate of the Environment in Gdańsk and the Gdańskie Wodociągi company. The prosecution emphasizes that this is only the beginning of the proceedings. It is necessary to determine what type of waste went to the sewage system and where it could have come from.
