WebSoil vapor extraction (SVE) involves the use of multiple air injection points and multiple soil vapor extraction points that can be installed in contaminated soils to extract vapor phase contaminants above the water table. Contamination must be at least 3 feet (0.91 m) deep beneath the ground surface in order for the system to be effective. WebDuring droughts, groundwater extraction may increase to offset the low availability of surface water and groundwater levels decline. In periods of high rainfall, demand for groundwater decreases and this allows groundwater levels to recover, sustaining a reliable and secure water resource. bas salaire
