SOIL AND GROUNDWATER REMEDIATION

Commercial and industrial operations have the potential to contaminate the soil and groundwater on a site. At a site with contamination levels exceeding acceptable limits, soil and/or groundwater remediation may be necessary. AFI can assess a site and determine the best approach to remediation by looking at a variety of factors, such as the number and types of contaminants involved and the depth to groundwater. Soil and groundwater investigations are not only to determine if contamination exists, but also to determine the extent and root cause of any identified contamination. AFI has conducted a wide array of subsurface investigations, from underground storage leak detection to extensive site investigation with a large number of boreholes throughout the property. AFI's professionals have knowledge in all soil sampling protocols and regulatory requirements.

Groundwater investigations include well installation and development, field sampling and analysis, groundwater flow determination, and interpretive contaminant hydrology. AFI has the experience to develop and implement ongoing groundwater monitoring.

AFI's diverse environmental capabilities and experience are the basis from which we approach site remediation and cleanup. AFI's scientists and field supervisors have designed and executed numerous site remediation and cleanup operations across the country. Accurate characterization of existing site conditions is a crucial part of managing every remediation project. AFI is experienced in array of remediation activities which include:

• Contamination source removal/disposal (i.e., oil/gas wells, pipelines, tank farms, etc.)

• Hazardous waste characterization, removal, and disposal

• Contaminated soil excavation, re-use, and/or treatment at off-site disposal facilities

• Contaminated groundwater management, treatment, and/or monitoring

AFI's thorough understanding of the regulations promulgated under RCRA, CERCLA, and SARA are paramount to AFI's success in achieving cost-effective and complete cleanup to applicable regulating standards or technical guidance values established by state regulatory agencies, the USEPA, or other appropriate regulatory agencies. AFI's routine contact with state agencies and the USEPA keeps AFI on the cutting edge of new environmental technologies. Finally, supervision of cleanup operations by field-tested scientists who understand and have demonstrated experience as equipment operators allow for AFI's cost-effective management of field activities.
