Water Quality Testing

Maryland Department of the Environment - Certified Water Sampler

We are licensed as a Maryland Department of the Environment Water Sampler and work with partner certified drinking water laboratories to perform water sampling services for real estate transfers, use & occupancy permits, new well certifications, adoptions, refinances, day care licenses, etc. Every residential well should have water testing performed once per year for bacteria.

Conventional Loans: Typically require a test for Nitrates, E-Coli, Total Coliform (Bacteria), Turbidity, and pH.

Frequently Asked Questions

Can’t I just take a bottle of water to a lab on my own?
If the water testing results are going to be submitted to a regulatory agency (MDE, EPA, County Health Department, financial institution), it most likely requires a certified sampler. This ensures a proper chain of custody and allows results/procedure to be defended in court. Different tests require different containers and procedures. It is not worth the risk to save a few bucks by performing an amateur DIY test.

What about these plumbing companies that provide free testing?
Unfortunately, most of the time they are offering the testing because they want to sell their treatment services. In other cases, the free test is very basic with additional tests for a fee. I am an independent third-party who holds nothing to gain by whatever the results say and will not up-sell you.
