A method for cleaning a contaminated reason water region

摘要

A high pressure water injection process reduces the time taken to remove chlorinated hydrocarbons and other poorly soluble substances from contaminated ground water. The water is introduced into the core zone of soil containing the contaminants and hydraulic measures are then taken to increase the flow speed of the ground water in this zone. A high pressure water injection process reduces the time taken to remove chlorinated hydrocarbons and other poorly soluble substances from contaminated ground water. The water is introduced into the core zone of soil containing the contaminants and hydraulic measures are then taken to increase the flow speed of the ground water in this zone. The measures may include removal and processing of contaminated ground water, or the injection of water at high pressure and creation of strengthened sub-surface barriers or seals. The high pressure water is introduced as an impulse, at intervals or non-continually using drill holes, bore holes, springs or rinse filters.
