Air Pollution Testing, Project Management & Calibration

From project management to equipment testing, McHale Environmental handles all aspects of the emissions and air pollution measurement process. Our strategic location in the Research Triangle Park in Durham, North Carolina allows us to access data banks and personnel at prominent organizations. These include Duke University, the University of North Carolina, North Carolina State University, EPA research branches, and the EPA emissions testing center and libraries. McHale also is able to develop informal networks with other testing and analytical firms in the area. This collection of knowledge and expertise is used by Air-Tech to ensure the most current testing methods, equipment, and information are made available for our clients.


Industrial Plant

Project Management

McHale Environmental assigns a project manager to coordinate team activities in planning a test. The project manager will receive input from the client, and in coordination with the team members, prepares a proposal, and a test plan or protocal. Once the project is assigned, the project manager will participate in all phases of the technical effort to ensure continuity and quality control, overseeing each aspect of the test, keeping the client informed of the progress, and providing on-hand expertise. Once the project is completed, the project manager will review the data and submit a report to the client for final approval.

ERT Reporting (Electronic Reporting Tool)

We are a leader in the ERT area. As part of project management, we ensure total quality control by putting together a comprehensive reporting package for the client for every test project requested. All protocols, plans, and reports are compiled and reviewed by senior staff. From developing testing protocols and advising about health and safety to Quality Assurance Project Plans (QAPP), trial burn plans, and detailed final reports, we cover all aspects of testing.

Calibrating & Maintaining Equipment

McHale Environmental recognizes the importance of up-to-date and well-maintained equipment. Equipment failure can delay a test and give incorrect data. Therefore, all equipment is maintained and calibrated according to the QA/QC requirements listed in Volume III of the QA Handbook for Air Pollution Measurement Systems. Also, Air-Tech will take duplicate equipment needed on a test site to ensure no delays. To control costs for the client, some equipment is rented or leased. In such cases, the equipment is tested and calibrated (if necessary) before use in the field.
