Environmental Enlightenment #236

Issued January 29, 2018

This is a SHORT, LIGHT and SIMPLE newsletter. Its purpose is to rekindle in the initiated concepts they have once learned, and enlighten the uninitiated on concepts they may have never heard of, but will understand once they are introduced to them.

Exploding Grounds

A street widening project. A section of a property along the street has been acquired by the City and a new sidewalk is being constructed. The construction crew encounters a buried 1.5" steel pipe running across the intended side walk.





Using an electric saw, they start cutting. The sawed side of the pipe emits a puff of smoke and six feet away a crater opens with a volcanic blast hurling dirt and rock. By sheer luck, nobody gets injured.






We are retained to investigate, and we find two historical 500-gallon gasoline tanks buried underground with piping running to the locations of historical pumps some 30 feet away. The tank that connects to the sawed pipe is the one that exploded. Its end is ripped open. The sawed pipe used to be a vent line.

(1)  Safety: Do not perform hot work on abandoned buried piping until it has been traced to its origin. As a minimum, test the interior atmosphere and determine if it is explosive.

(2)  Property transaction: A Phase One Environmental Site Assessment process would have been likely to find evidence of the tanks. Old building permits, business permits, fire insurance maps, aerial photography, etc., would have had a good probability of locating data pointing to the historical tanks. An after-the-fact interview of the site occupant revealed knowledge of the historic installation.


You can find past issues of our "Environmental Enlightenment" at amiadini.com Wealth of information about environmental site assessments in the real estate transactions and issues concerning assessment and cleanup of contamination in the subsurface soil and groundwater.

Call me if you have any questions. There are no obligations.
