CERCLA - Our staff have been involved in the CERCLA program since 1989. Our experience spans site investigation (PA/SI, EE/CA and RI/FS), Risk Assessment, Remedial Design/Remedial Action, Time-Critical Removal Action, and Non-Time Critical Removal Action projects. Our site investigation services range from real-time metals analysis via portable XRF technology, to laboratory sampling of surface water, groundwater, soil, air and biological media, and evaluation of human health and ecological risks. We have provided our CERCLA expertise in a variety of settings ranging from alpine environments above 9,000 feet in the mountain of Colorado and Utah to inner-city locations. We can assist our clients in regulatory negotiation, project management, and site closure. Our CERCLA projects include sites in California, Colorado, Missouri, Montana, Utah and Washington.
