Environmental Services



McHale’s Environmental Services provides emission testing programs designed to meet each client’s particular needs with experienced and professional emissions measurement teams overseen by a staff with over 25 years of experience in the source testing industry, including both domestic and international testing projects. The McHale team consists of engineers and technicians, dedicated to providing our clients with accurate and precise test results.

McHale is equipped with the latest emission measurement equipment, ensuring the best technology to provide precise, reliable, test results. McHale is noted for its ability to meet the client’s needs, whether it is a 24-hour continuous testing or a short-notice mobilization. We can mobilize for most applications within 24 hrs. We are highly efficient at testing multiple sources simultaneously, while effectively communicating with facility personnel to provide real-time emissions data, correlating with process and control variations.


McHale’s Environmental Services provides emission measurement solutions to a variety of industries. Sources tested include pulp & paper mills, IC engines, and generators, boilers, turbines, thermal oxidizers, BIF sources, incinerators, and refineries.

McHale offers expert site teams to support your project and specific testing needs. McHale can take samples to analyzers and either take samples to send to an Accredited laboratory or directly provide on-site analysis for many different constituents. A summary of our on-site analysis and sampling capabilities is listed below.
