As with soil remediation, Brown Environmental favors onsite remediation techniques designed to destroy or recover contaminant mass. Brown Environmental has designed and fabricated four injection systems to account for variations geologic media and amendment materials. Additionally, specialized delivery techniques have been developed to maximize application efficiency including pneumatic and hydraulic fracturing, water flooding, infiltration trenches, horizontal wells and seepage pits. Physical recovery of subsurface contaminant mass is often used to compliment injection techniques and is most commonly accomplished through either vacuum recovery or pumping methods.

Brown Environmental specializes in the following groundwater remediation techniques:
