Field Studies and Sampling
ERG supports our clients' sampling and testing programs, including design and planning, execution, and the interpretation and effective presentation of results. Our teams include chemists, environmental scientists, chemical and mechanical engineers, and highly trained technicians. Our staff has completed EPA Inspector Training and meets OSHA HAZWOPER requirements for working at hazardous waste sites. We conduct studies of all environmental media (air, water, wastewater, soil, and sediments).
ERG designs and executes specialized programs that fit each client's needs. We don't just take measurements—we help our clients identify the type and quality of data they need for informed decision-making.
