Article first time published onHow do you remediate groundwater contamination?
The most basic type of groundwater remediation, uses air to strip water clean (air sparging). Another method, called pump and treat, physically removes the water from the ground and treats it by way of biological or chemical means. Both of these methods have proven successful in treating contaminated groundwater.
