Project managers

Good people make for good results. Our three project managers are with you every step of the way, making sure you get accurate results on time and on budget. They understand your business and the challenges you’re facing. They work with you to define your project requirements, then work closely with our laboratory and quality management staff to ensure your requirements are met.

Flexible turnaround times

Our typical turnaround time for most analyses is 10 days (the industry standard). But we understand that in the real world, you often can’t wait 10 days for results. Our Project Managers will arrange for expedited turnaround times to meet the needs of your project.

We know permits

With our knowledge of the permit process (Drinking Water, NPDES, Pre-Treatment Agreements, etc.) we’re able to partner with you to manage your permits. We’ll help you interpret the analytical requirements of your permit and schedule the appropriate testing on time.
