Setting: Jericho Springs, a small town in rural Missouri
Population: 247
In this town was a small grocery and gas station setting on top of hill. One day a car comes over the hill and loses control running into a gas pump knocking and it over. The customers uprights the pump and fixes broken pipe at the pump and all is well. Customer then started pumping gas again without realizing that a crack has appeared where the pipe connects to the tank below ground.
For approximately 2 yrs as the customers pumped gas into their cars, they were also pumping it into the ground below. You could literally smell the gas as you drove up the hill to the store. The ground was totally gas saturated. EPSI was contacted by Mr. Dominic Whitley of Mid America Environmental in Cartage, MO to discuss the effectiveness of their patented liquid/liquid separation because the oil/ water separator, air stripper and multiple carbon columns they had installed were not working.
They could not get close to their discharge limits. After a brief study of this case EPSI suggested that they install a liquid/liquid separator between the oil/water separator and air stripper and an EPSI EZ FLOW media column using Biomin’s EC-300 organoclay, a clay modified specifically to remove MTBE.
After eight hours of operation the new system had dropped BTEX levels from 22,385ppm to N/D. Their goal was 800ppm. MTBE levels from 7,762ppm to 0.045ppb. Their goal was 400ppm.
These results were provided by Mid America Environmental, the engineering company hired to clean the site.
