The Field Services Unit performs emergency response duties and provides field support services for programs within the department and other state agencies. Staff also help provide field sampling support as needed.

Field Services Unit staff have the training, experience and equipment to conduct investigations to provide field support to the department’s Hazardous Waste Program. This involves collection and analysis of various environmental media and potential hazardous wastes at:

The unit also provides technical document reviews, environmental assessment services, equipment and extensive field sampling support services at a variety of abandoned hazardous waste sites, regulated facilities, and petroleum tank sites.

Personnel are proficient with several pieces of specialized in-house equipment used to collect high quality soil, water, and air samples for analysis. The department’s in-house laboratory analyzes a majority of samples collected to provide managers with the information necessary to make decisions and assess risks posed by individual sites.

Examples of in-house equipment used at investigations include:
