Alliance Source Testing, formerly E. Roberts Alley & Associates, Inc., is one of the premier source testing companies in the United States. We are a full-service emissions testing company offering a comprehensive range of engineering, consulting, and field services to assist you with your source testing needs. With offices strategically located to provide national coverage, we bring a holistic approach that yields cost-effective solutions designed to meet your needs. Originally a division of E. Roberts Alley & Associates, Inc., Alliance emerged as its own company in 2009 in order to serve our clients better by focusing exclusively on source and emissions testing.

Every day we do something to make the world a better place. Although our technical focus is on working with you, our clients, to monitor your emissions, our overarching focus is to pursue the truth and strive for excellence in our work and in ourselves. By doing so, together we can continue to do our part to preserve our way of life and make it better for future generations. We strive to be all we can be, never compromising the integrity of our work, and delivering on every promise we make.

The higher standard we set for ourselves, the better we can serve you.

Alliance, under the name of ERA&A, has been providing emission testing services to industrial clients since the mid-1990s, and we are proud to now be operating under our new name, to reinforce our commitment to you and your needs. We have conducted hundreds of emissions testing programs utilizing a significant number of different EPA, SW-846, NCASI, ASTM and NIOSH test methods. These test programs have been performed for a variety of reasons including:

• Compliance demonstration
• Air pollution control device (APCD) design
• APCD guarantee demonstration
• DRE evaluations for Thermal Destruction and Recovery studies
• CEM installation and performance specification validation
• Process and control device troubleshooting and optimization
• Boiler tuning
• Ambient air monitoring
• Predictive emission monitoring system validation
• Toxic release inventory reporting
• Permitting and dispersion modeling support
• Worker exposure evaluations

All of our Project Managers, Field Supervisors, and Field Testing Personnel have the appropriate training, experience, and qualifications to provide quality emissions testing while minimizing our on-site time.

Alliance has extensive testing experience in many different types of industry including Asphalt, Automotive, Chemical, Food and Beverage, Fiberglass, Foundry, Mineral Processing, Natural Gas, Petroleum Refining & Terminals, Power Generation, Printing, Pulp/Paper, Primary & Secondary Metals, and Wood Products facilities.

Alliance project managers and senior management are QSTI certified and/or registered Professional Engineers – we have set our internal standards high so we can take care of you well.

QSTI - The Qualified Source Testing Individual (QSTI) program is conducted by the Source Evaluation Society (SES) as a service to the source testing industry that quantifies the knowledge and expertise of a source tester.  The source tester must demonstrate the knowledge and the ability to apply source testing methods and fundamental engineering and chemistry principles in a manner consistent with that of a field test team leader. In addition to thorough and practical knowledge of source testing methods, those principles include an understanding of elementary physical gas laws and chemistry, basics of safety and hazardous material handling, and primary theories of source testing (e.g., isokinetic and proportional sampling).   The QSTI program has set the standard for individual certification in source testing. Alliance Source Testing personnel are currently Group 1 and 3 certified.
