Elk Grove Pump Stations
Elk Grove, California

While explosive gases are fairly common in sewers, it is possible to produce explosive gases in stagnant storm drains too.  The City of Elk Grove was improving six pump stations and wanted to determine if decaying vegetation in their storm drain pump stations was creating liquids or gases that could result in an explosive environment.  Geocon collected samples of liquid from each of six pump stations and screened the vapor at various depths to check readings against the lower explosive limit.

Interesting Fact: The lower explosive limit is the minimum concentration of a particular combustible gas or vapor necessary to support its combustion in air
