Farallon incorporated groundwater circulation wells in the design of an innovative system to treat petroleum hydrocarbon-contaminated groundwater at a retail gasoline station. The system included airlift air...

After Farallon successfully completed cleanup of a former dry cleaning facility on a client’s property, groundwater at another portion of the property was discovered to be impacted by the dry cleaning...

Farallon has been leading an investigation to evaluate releases of per- and polyfluoroalkyl substances (PFAS) in the Lower Issaquah Valley in Washington State. Following initial detections of...

To delineate the extent of the contaminated soil and groundwater, Farallon initially completed a subsurface investigation. Farallon then conducted a remedial alternative and cost-benefit analysis feasibility...

Farallon’s client had a vision for redeveloping a Seattle property used as a landfill from the 1930s through the 1960s, and required Farallon’s expertise to make that vision a reality.

Design elements included stormwater management facilities; water and sewer utilities; natural gas, power, and telecommunications utilities; waste handling; delivery, employee, and visitor vehicle access and...

When multiple attempts to treat recalcitrant contaminants with conventional technologies failed, Farallon proposed using surfactant injection to increase mobility and recoverability of light nonaqueous-phase...

Surfactant injection, an innovative remedial alternative, can increase mobilization of LNAPL and ease of capture to reduce the cost and duration of attaining a No Further Action determination. Farallon...

Remedial actions previously conducted by others included source removal, soil vapor extraction, and air stripping/hydraulic control of groundwater. The current remediation system treats emissions via thermal...
