Zia Environmental navigated an extremely contentious project with us. They not only proved to be responsive, professional, and knowledgeable in their area of expertise, but they also always took the time to thoroughly explain pertinent information and address the opposing parties (baseless) concerns immediately. They are truly a joy to work with and we look forward to continuing our partnership on future projects.

I have worked with Zia Engineering for the last six years on numerous projects both completed and current. They are very capable and offer a diverse array of services with staff that are well trained for their various specialties. I would highly recommend Zia Engineering.

Thank you for the work that you did to accomplish the cleanup and closure of the Gibson Fryburg site! This was a major project that presented a number of surprises during excavation, and your on‐site crew did a phenomenal job of dealing with and adapting to each new challenge. I’m certain that their cooperation and flexibility were due in large part to your guidance and instruction, and I thank you for your part in ensuring that the project kept moving forward, rather than stalling at each unexpected turn of events.

Zia is professional and timely on all projects that we have worked with them on. They are quick to respond to any questions or comments and stick to the project timelines. We appreciate their positive attitude and will continue to keep working with them in the future.

Zia provided an excellent response to a major request for proposal issued on behalf of my Cultural Resources/Natural Resources/NEPA program at Holloman Air Force Base. Their response demonstrated that they thoroughly considered our data and resource management needs. Then, with comprehensive, timely and expert fieldwork, reporting and document preparation, Zia delivered excellent results that answered our needs. I am well pleased with their work.

Performs all work such as hazardous wastes, environmental assessments, and archaeological and biological surveys on time, even if we need something with a very fast turnaround.
