Work after kerosene leak begins Monday

On Monday, work will begin on the Garching campus to pump out groundwater contaminated with kerosene. Specialist companies will sink two wells for this purpose. The water will then be cleaned so that it can be fed into the sewer system. More than 5,000 liters of kerosene had leaked from a utility building during a construction project, most of which seeped into the soil.

Last week, a company had been commissioned by the State Construction Office to renew a pumping station that pumps kerosene on demand from an underground tank into a laboratory building located next to the Department of Mechanical Engineering, which is also used by the Department of Aerospace and Geodesy. The fuel is needed there in propulsion research. Last Monday, a TUM employee discovered that kerosene was leaking from the system. The company was immediately informed and stopped the leak.

Investigations by a commissioned expert revealed that the kerosene spread in a localized area in the soil. It can be assumed that this area has a maximum extension of 25 to 30 meters. The soil will be monitored in order to advise on the need for treatment if necessary.

No one was injured. TUM is working with all involved parties and relevant authorities to investigate the causes of the incident.
