► Shield’s comprehensive remedial strategy is geared toward the ongoing effort to ensure the safety of on-site workers,
the public, and the surrounding environment.
►Remediation can involve the removal of the waste/source; waste stabilization; providing innovative, cost-effective
corrective actions; and ultimately clean-closing or properly containing contamination, as appropriate.
►Shield’s personnel have extensive experience with a variety of technologies including monitored natural attenuation,
bioremediation, phytoremediation, chemical oxidation, soil vapor extraction, dual-phase extraction, reactive barriers, soil
flushing, and various pump-and-treat scenarios.
After the project options and issues have been identified, Shield works
closely with the client in selecting a remedial action plan that will
accomplish the desired results. When excavation and clean closure is
selected as the appropriate remedy, Shield creates a design to
minimize the amount of material to be excavated and often includes
waste segregation activities to further reduce treatment/disposal costs.
In some cases, site containment is the selected remedy and Shield
will execute a design that will include the appropriate type of cap or
cover, e.g. RCRA, modified RCRA, asphalt, etc.

Remedial Design / Remedial Action
Often industries must address contamination issues
posed by past disposal practices, and when
remediation is necessary Shield provides turnkey
services for our clients. Our engineers and
scientists have created groundwater and soil
treatment designs, industrial and hazardous waste
site closure plans, and corrective action plans for
project sites throughout the United States.
The remedial design is highly dependent upon specific project conditions including:
■ Contaminant source(s), concentrations, and media classification;
■ External characteristics;
■ On-site and off-site structures;
■ Fate and transport;
■ Property and surrounding land use; and
■ Specific regulations and agencies involved.
