Align Capital Partners-backed Alliance Technical Group, a provider of air quality testing, monitoring and source emissions testing services, completed the acquisition of Air Quality Services, a provider of environmental services. Financial terms were not disclosed. “Strategically AQS fits from both a geographic and service offering perspective for Alliance. In addition to adding experienced stack testing and ambient air monitoring professionals, we are entering the CEMS market which allows us to provide our customers with services they have been asking us to include in our offering. We will continue to look for opportunities to partner with high-quality companies and people, like the AQS team, making us stronger and better positioned to meet our customers’ air-related requests," Chris LeMay, Alliance CEO.
