CATLIN has extensive experience in designing and carrying out environmental site assessments and contamination investigation activities under varying geologic and hydrogeologic conditions. We routinely perform contaminated media assessments associated with a variety of sources pursuant to Local, State and Federal regulatory requirements. Project experience includes sites such as Superfund sites, commercial and hazardous waste landfills, dry cleaners, industrial solvent spills, fire training areas, chlorinated solvent contaminated sites, maintenance yards, POL storage and distribution areas, bulk fuel storage facilities, pipeline releases, maintenance facilities and refueling stations.

CATLIN constantly seeks ways to accelerate the investigative process by implementing innovative strategies including working on multiple phases concurrently using a non-phased sampling and analysis approach, and maximizing the use of field screening techniques and flexible work plans. Field screening techniques include geophysical methods, such as electromagnetic (EM), seismic refraction and ground penetrating radar to delineate buried debris and contaminant plumes; in-house direct push sampling techniques for soil and groundwater sampling (Hydropunch and PowerProbe); vertical and horizontal drilling techniques; advanced site characterization using Membrane Interface Probe (MIP) and mobile laboratories; field screening analyses and on-site laboratories to generate results that allow real-time decision making.
