Accurate test results begins with proper sampling techniques. Not only do we perform laboratory testing, but we’ll collect your samples at your site beforehand. We tailor our services to meet your needs.

Call us to set up sampling services or order a self-sampling kit: (616) 364–7600.

If you prefer to collect your samples yourself, please follow these instructions according to the sample type:


Reporting Results

Waiting on test results can hold up your project and delay your response time. After testing, we’ll send your results in the format you want and make sure you understand them. We will help you understand and meet environmental regulations.

Our average turnaround time is five business days, but high-priority jobs can be done sooner if arranged.
