Indoor air quality
Because reliable data is the foundation of a successful air monitoring program, the strictest standards are applied to the operating methods. The quality assurance audits are based on the National Institute for Standards & Technology for traceable gases. The firm has developed and rigidly followed procedural and maintenance manuals for monitoring that meet all of EPA's current guidelines. Our staff and technicians have a thorough knowledge of ambient air monitoring instruments.

Service to Shell Engineering means meeting the customer's needs successfully and in a timely manner. Assistance and training are offered to those who wish to purchase the monitoring equipment, maintain it, audit it for quality assurance and provide data for themselves. In other operations, complete turnkey sites are established. The client is then provided reliable and acceptable data for permitting. Of course, air monitoring consists of more than working with numbers and equipment.

A client with special needs in dealing with governmental agencies will benefit from Shell Engineering's good working relationship with governmental agencies and its knowledge of what these agencies require. The firm can advise the client on PSD permitting and provide experienced expert witnesses for various legal cases.
