<p>A method and system for forming an in-situ subsurface filter in a contaminated aquifer, and for removing contaminants from groundwater drawn from a contaminated aquifer (12). The filter is produced in situ by injecting an aqueous solution comprising bacteria-stimulating chemical components through a well (10) to bioactively generate a subsurface mineral filtering zone surrounding the well. As water is subsequently drawn through the well, contaminants are removed from water as it passes through the filtering zone.</p> |
