Alliance helps prevent costly fines and production interruptions with comprehensive and timely assistance in emissions stack testing. With the largest national network of qualified resources, Alliance ensures you have the right team at your site at the right time to meet both your compliance and your operational needs.


We invest heavily in creating a system that ensures the reliable delivery of services. The foundation of that effort is The Alliance Advantage which defines our commitment to executing projects quickly and efficiently. We guarantee that you will:

  • Receive a cost proposal within two (2) business days following the development of a firm scope of work;
  • Receive a test plan within two (2) business days following the receipt of documentation to proceed; and,
  • Receive a draft test report within two (2) weeks following the completion of fieldwork or within two (2) business days following receipt of laboratory data.


Alliance’s expertise in regulatory compliance, source testing methods, and our commitment to safety means that no situation is too challenging for us to perform safely and correctly. Our source testing staff includes experienced scientists and QSTI qualified Project Managers (PM) who execute and oversee field testing for our customers. Our team of stack testing specialists, our accredited Particulate Matter (PM) laboratories, and our fleet of FTIRs and operators give us the ability to provide quality and timely source testing services to customers throughout North America.


Our network of qualified subject matter experts, project scientists, and mobile source testing laboratories provide nationwide coverage for our customers. Our corporate-wide proprietary scheduling and project management platform allows us to fully leverage this network to proactively schedule projects, confirm on-site test teams have the required training/certifications and provide qualified test teams. In essence, working in tandem, they allow Alliance to mobilize the right test team and equipment to the right place at the right time.
