Harris County Precinct 1 Constable Alan Rosen's office first revealed the investigation early Friday afternoon.
According to Rosen, his environmental crimes unit is serving a search warrant in the 1000 block of Church Street, which is located next to the San Jacinto River Authority Canal.
Pictures of the buried oil were posted to Rosen's Twitter account. Rosen tweeted investigators are digging for the source of the contamination, and that oil was found as far as a quarter-mile away.
The exact amount of oil buried at the site was not immediately disclosed, as well as who may have buried it there.
