Site Assessment and Remediation:
Groundwater Services

Barr routinely performs groundwater sampling as part of contaminated site investigations and remedial action effectiveness monitoring programs. Our staff is experienced with a variety of sampling techniques, including low flow sampling protocols for trace (ng/L) analyses of PAHs and mercury.

We also have groundwater modeling and contaminant transport assessment specialists on staff. Their expertise includes developing regional-scale and site-specific groundwater flow and contaminant transport models for a variety of contaminated-site investigation and remediation projects, as well as for wellhead protection studies. These projects involve two- and three-dimensional steady-state and transient modeling.

Our groundwater specialists consider a wide range of alternatives when determining solutions for remediating contaminated groundwater:

• Air sparging
• Groundwater pumpout and treatment—UV/oxidation, packed tower aeration, granular activated carbon adsorption, organophilic adsorption media, biological treatment, cascade aeration
• Monitored natural attenuation
• Plume management
• Isolation by barriers (for example, slurry walls)
