Markets and Services


Client-Focused Support

For more than four decades, EA’s unique and long-term business relationships have formed the very cornerstone of our success.  We may be a multifaceted firm operating in multiple markets, but we take a decidedly individualistic approach to client service.  We have organized ourselves internally to provide market-specific services, and ensure that each client is assigned an experienced project manager with a proven record of success in that specific area.

We are equally adept at supporting public and private sector clients

EA has completed thousands of projects worldwide for a highly diverse client base that includes the federal government, states and municipalities, utilities, private industry, Fortune 500 companies, trade associations, academic institutions, law firms, non-profit organizations, and others.

85 percent of our new contract awards come from repeat customers

We operate under a singular vision of customer service that is based on the highest levels of integrity.  Discerning clients look to EA for solutions to their most vexing environmental and infrastructure challenges.  Our integrated project delivery teams make it their priority to provide consultative work products that articulate defensible conclusions and sensible options to move projects forward.  That is why our very first client from 1973 is still our client today!

At EA, client satisfaction is more than just a goal.  It is our way of life!

Our long history of providing high quality work, on time and within budget, is evidenced by repeat business, technical achievements, outstanding federal Army Contract Assessment Support System (ACASS) ratings, and letters of appreciation and commendation.  We continually strive to provide our clients with “Best Value” and to excel in areas of project performance that are critical to all of our clients: quality service, timeliness, cost control, safety, innovation, and responsiveness.

Our Markets


The Depth and Breadth of Experience You Need

EA was founded to help power producers comply with Section 316(b) of the Clean Water Act; and, while our service offerings and client base have grown considerably over the years, we continue to remain focused on addressing environmental issues.  Having completed thousands of projects and performed more than $2 billion in services, EA is a leading provider of environmental, engineering, compliance, information technology, natural resources, and infrastructure management solutions to a wide range of public and private sector clients.  Over our 48-year history, EA has garnered an outstanding reputation for technical expertise, responsive service, and judicious use of client resources.  EA is an employee-owned public benefit corporation with more than 500 professionals operating through a network of over 25 commercial offices across the continental United States, as well as Alaska, Hawaii, and Guam.  We offer interdisciplinary project teams experienced across a variety of regulatory, political, geographic, and technical frameworks, all trained to adhere to our well-established and integrated quality and safety programs.

Delivering “Best Value” Solutions

EA’s professionals guide our clients through change by developing fully integrated solutions to help them solve their environmental and infrastructure problems and meet regulatory and business objectives.  By truly integrating engineering, science, and technology, it enables us to formulate outstanding responses and assist our clients in ways that are environmentally sound, fiscally responsible, technically defensible, and operationally efficient.

Industry Involvement

EA is dedicated to serving the needs of public and private sector clients worldwide.  Since our founding in 1973, we have helped industry and government improve their performance and achieve their environmental and organizational objectives.  We are members of leading organizations to ensure we remain in the forefront of the latest developments that affect our industry and our clients.
