Multi-Media Sampling, Sample Management, And Quality Control


When media sampling is required, chemical analyses of the samples provide the concentrations of the individual compounds present. Evaluation of the chemical data, combined with site-specific knowledge of the facility can identify the sources(s) and contaminants of concern. The successful site investigation, and ultimately risk reduction, is largely dependent upon a well-planned and executed site-sampling program. Multi-media sample collection and analysis provides the basis for sound environmental decisions.  GEM's monitoring programs are designed with the projects specific goals and requirements to obtain accurate, timely results in a helpful and flexible format. Our experience spans design and execution of sampling programs for hazardous waste, surface water, illicit discharges, groundwater, ambient air, indoor air, soils, sediments, sludge, facility maintenance activities, industrial process streams, and biota.

GEM provides expert monitoring services for all environmental media. Once analytical results are obtained, GEM provides data validation and interpretation services to help the client make informed decisions on further courses of action. Other key elements of our investigation and sample and analysis program include:
  • Customized sampling and analysis programs using current technologies and innovative techniques to achieve specific project goals.
  • Multi-disciplinary monitoring using state-of-the-art-sampling techniques and State and federally accepted protocols for sample collection, sample handling, and documentation to ensure sample integrity while placing special emphasis on health and safety and quality assurance.
