They call it progress .. but I miss the old Santa Anna capture site on the Houston Ship Channel

Euthanizing bird flocks  PURGIT has a vaporizer that could be used to euthanize birds to control the spread of viruses. We also have experience in displacing air from large spaces and inserting inert gas that will not support life or combustion.

Test cargo tanks for nitrogen leakage    We can set up battery powered equipment to do storage tank monitoring. This can help identify leaking seals and or pressure / vacuum valves.


Soil remediation   PURGIT built ground water suction units. They have vacuumed up hundreds of thousands of gallons of ground water as they remediated the earth around a pipeline spill.
