About Us

IM000296.JPGAlliance Environmental Group (AEG) is an environmental services and engineering corporation with offices in Warwick, Rhode Island, and Cambridge, Massachusetts.  AEG was established in 2001 by Richard Hittinger, MS, and Michael Geisser, PE, LSP, along with a staff of experienced engineers, scientists and technicians.

Mr. Hittinger remains the active principal in the firm with over 30 years of experience in environmental engineering and consulting.  All the personnel at AEG are expert in developing and managing environmental investigations and designing and implementing environmental remediation.  AEG provides professional services in the areas of environmental studies, permitting, design, emergency response and remediation.  AEG is a Registered Professional Engineering Firm with the Rhode Island Board of Professional Engineers.

The key professionals at AEG have many years of experience in areas ranging from Phase I Site Assessments to Stormwater Pollution Prevention Plans (SWPPPs), to designing and operating remediation systems for the cleanup of contamination and complete site restoration following the cleanup of environmental releases. AEG is always searching for new, more modern technologies in order to consistently provide our clients with the best possible solution to their specific problem or issue.  Our reputation amongst regulators and the regulated community is second to none.

AEG has completed numerous Phase I and Phase II Environmental Site Assessments as well a wide range of Rhode Island Department of Environmental Management (RIDEM) and (Coastal Resources Management Council (CRMC) permitting.  Also of particular note are the major Brownfields projects that AEG has managed for some of our clients.  Many requirements have to be met while working on Brownfields projects, and this often necessitates intense coordination with the U.S. Environmental Protection Administration (USEPA) and high profile community public relations.  Overall, our unique strengths are communications and strategic planning for sensitive environmental projects.  In addition, all of our projects are staffed with key AEG professionals and supported by our highly qualified subcontractors.  This has been a formula for success for AEG on many past projects, and we have developed strong relationships with the most qualified subcontractors available in the Northeast.
