Interpretation of Drinking Water Tests


Much more than water testing…

Waiting on test results can hold up your projects and distract you from important work. Let P&N take care of the details. You can count on us for high quality, well-documented, scientifically sound results.

We test water and soils for:

  • Lead and Copper
  • Organics
  • Other Metals
  • Inorganics
  • Microbiology
  • NPDES/IPP Compliance Monitoring
  • PFAS

We’ll even collect your samples at your site.

After testing, we’ll send your results in the format you want and make sure you understand them. We can help you understand and meet environmental regulations. The average turnaround time is five business days, but rush jobs can be done sooner if arranged.

Need help with remediation? We do that, too.

When you trust your laboratory testing to P&N, we tailor our services to meet your needs — leaving you free to focus on more important things.  For more information, contact us at (616) 364-7600.
