Since our inception in 2000, ETI has focused on providing our customers with reliable data at competitive turnaround times. That focus pushes us to constantly evolve as a company to ensure that our clients can always depend on their results to make informed decisions. We understand our support role and make the success of each client a priority. Standard turnaround time on most analyses is five (5) business days to help you complete your project effectively and efficiently. Rush services are also available.


We specialize in the analysis of aqueous and solid matrices. Our Oklahoma City laboratory is NELAP (National Environmental Laboratory Accreditation Program) accredited and has the capacity to analyze these matrices by GC/MS (Gas Chromatography/Mass Spectrometry), GC, ICP (Inductively Coupled Plasma) to name a few. Combining the use of state-of-the-art instrumentation with years of analytical experience, gives us the ability to perform our analyses accurately and efficiently. These capabilities make ETI a dependable partner for our clients. Here are just a few of the projects for which our data provides valuable information:

  • UST (Underground Storage Tank) assessment, removal, and remediation
  • Hazardous Waste Characterization
  • Wastewater compliance monitoring requirements
  • Site assessments and remediation
  • Phase II Environmental Reports

One of our most beneficial strengths is our ability to quickly adapt to the needs of our clients. Our NELAP and state certifications in Oklahoma, Texas, Kansas and Louisiana give confidence that your results are the most accurate available and our small business culture adds a personal relationship to each project. Having a team that you trust every step of the way helps you manage your projects more effectively.


Even with all of the technical capacity available at ETI, we are first and foremost a service provider. Our data reports are our product and your experience in receiving them is our service. ETI's deliverable options have been created with that in mind. We are able to provide you with your results in many different formats. We understand that there are ways we can work for you that may make your life a little easier. We are happy to provide pre-printed labels and Chain of Custody forms for your sample kits. You will never be charged for any containers. If we can make the process easier, that means you can complete your work that much more quickly.
