  "definition": "1. Injecting air or oxygen into groundwater to strip or flush volatile contaminants up through the groundwater as air bubbles and capture them with a vapor extraction system.\n\n2. Injecting air or oxygen into an aquifer to strip or flush volatile contaminants as air bubbles up through the ground water and is captured by a vapor extraction system.\n\n3. An environmental cleanup method that bubbles air through contaminated groundwater to transfer volatile contaminants from the groundwater to the soil gas, which then conveys the contaminants to the surface, where the contaminants may be captured or allowed to disperse in the atmosphere. Air sparging systems are often used together with soil vapor extraction systems.",
