Fluid Migration in Utility Trenches 1

[SanEnr1]

I am doing research for a paper regarding fluids (either liquids or gasses) that follow utility trenches after construction is complete. I have seen groundwater follow porous stone bedding materials downgradient and volatiles follow the same type material upgradient where the fluid is then released into the environment.

If anyone has experience regarding this topic or has read other papers on the issue, I would like to hear the story of the problem and how it was resolved.

Thank you.

We are usually instructed to install clay or other impermeable stanks at intervals along the trench
