Leaking fuel from a Matraville petrol station has significantly polluted soil and surrounding groundwater, prompting an investigation into potential health impacts on nearby shop workers and residents.
The NSW Environment Protection Authority (EPA) has issued 7-Eleven with a clean-up notice for its service station at 515 Bunnerong Rd.
A report released by the environmental watchdog stated monitoring found groundwater and soil had been significantly contaminated with petroleum hydrocarbons including cancer-causing benzene, toluene, ethylbenzene and xylenes.
The report said “the plume of contaminated groundwater … has the potential to migrate off site”.
The service station is surrounding by shops and is two doors down from St Agnes’ Catholic School.
An EPA spokesman said the contamination likely resulted from undetected leaks or spills during service station operations. The report stated potential “vapour intrusion risks” to surrounding properties would require further investigation.
“At this stage there is no evidence of risks to any other properties, however the EPA has required the operator to undertake further testing to assess any potential off-site risks,” he said.
“EPA officers have also door knocked nearby residents and commercial properties to inform them of the declaration”.
7-Eleven reported the contamination to the EPA after routine groundwater tests found it had been polluted.
