VPH offers Ex-situ groundwater treatment that removes contaminants from underground water, primarily using “pump and treat” systems that extract water and process it above ground with methods like activated carbon filters, air stripping, filtration, oxidation, or reverse osmosis, tailored to pollutants like hydrocarbons, metals, or volatile organic compounds (VOCs).
In-situ methods stimulate natural breakdown or use injected air/chemicals, while treatments often combine physical, chemical, and biological techniques for various pollutants, requiring permits for discharge.
