Worried about your water? We can help!

Since 1974, Prein&Newhof’s environmental laboratory has been performing water testing for drinking water, well water, wastewater, groundwater, leachate, and surface water, including nearly 18,000 microbiology tests each year.



Drinking Water

Prein&Newhof is one of the few laboratories in Michigan specializing in the analysis of drinking water samples. We are committed to delivering high quality, well-documented, and scientifically sound test results. Our goal is to help protect public health by aiding all clients in better understanding the results of their water tests.

We test water and/or soils for lead and copper, other metals, organics, inorganics, microbiology, NPDES/IPP Compliance Monitoring, and PFAS/PFOS. See below for more details on PFAS Water Testing.

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 and our sampling services follow EGLE Sampling Guidance.

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.
