About EAI

Our Mission

You can’t fix what you can’t see.

Knowledge is the first requirement of effective action. Our mission is to be the eyes and ears of environmental professionals tasked with keeping the water we drink, the air we breathe and the ground we walk on safe and free of contaminants. By providing our client/partners with knowledge in the form of accurate data and laboratory analyses, we help to ensure a healthy environment for all—now, and for the future.

Employee owned and operated since 1980.

Everyone who works at EAI is vested in the success of the company as only an owner can be. For us, success is personal. Providing the best experience we can for each of our client/partners is not some abstract goal in a business manual or sales brochure; it’s what we do every day. We measure our success by how well, how efficiently, and how accurately we meet the goals of those we serve.

Core Purpose: combining talents and technology with professional partnerships to help create a cleaner and safer environment.

Our Vision: to be the laboratory of choice within our marketplace, consistently delivering services of excellence, quality and personal attention.
