Yes, We Test Drinking Water!

Are you buying a new home or concerned about your current well water? Are you on town water but live in a old house with ancient plumbing? Give us a ring at 846-6569 to discuss your concerns!

We run drinking water tests of all kinds, including "basic safety" and common real estate panels. Testing for single elements of concern (arsenic, copper, lead, fluoride, uranium, etc.) is also welcome. See "Our Analytical Services" page for a full list of tests available.

Please note: MEL does not sell water treatment systems.

Short Holding Time Analyses

Download 2018 Short Hold Time Sheet with BOD/CBOD Calendar

“Holding time” is the maximum amount of time that may pass between taking a sample and starting analysis on it before it starts to degrade. Many analyses have short holding times—some as short as 8 hours.

We always make every effort to analyze your samples within the listed holding times. However, we cannot guarantee analysis within short holding time limits without at least 24 hours notice.

 ***ALWAYS CALL US 24 HOURS IN ADVANCE OF SAMPLING TO MAKE SURE WE CAN ACCEPT YOUR SAMPLE!***

What’s the big deal?

Samples that are analyzed beyond the recommended hold times may not be valid for compliance purposes.

Samples received beyond their hold times will not be analyzed without the express permission of the client, and data will be flagged as having been run beyond hold-time.
