Building-related illnesses are often related to HVAC systems, chemicals, or mold and sometimes to other environmental factors.

Mold Inspections

We can help in the most sensitive of situations. Mold colonization is a problem in any building. IAQ issues become much more serious when mold develops in a health care setting. ORION has provided expert support to the major hospital systems in the Seattle and Tacoma area. One of our areas of expertise is clean room Project Management.

Air Quality Testing

Our solution-seeking experts can solve complicated IAQ problems. ORION was called to a local health care facility where employees were experiencing an unusual odor, headaches, and nausea. Several agencies had investigated the site with no resolution. Our team evaluated the situation and discovered, much like in the picture to the left, a gasoline plume from leaking underground storage tanks at a nearby gas station as infiltrating the building.
