What we do is who we are.

We analyze water (drinking water, wastewater, groundwater, surface water, storm water), soil, sludge, oil and other matrices for potentially harmful environmental contaminants. We develop long-standing relationships with our professional client/partners, combining talents and technology with them to help create a cleaner, safer environment.

Service is our highest priority.

We are committed to unsurpassed customer service. Not only do we pay extra attention to the day-to-day personal interactions with our client/partners, but as a matter of course, we provide many extra services that make their lives easier. Some of these include electronic data delivery, courier services, technical support, provision of sample containers, automated bottle orders and technical seminars. In addition, our Field Services Department offers direct push services, equipment rental and experienced field technicians when an extra set of hands is needed in the field.
