What it measures

A broad screen identifying organisms present across the microbiology categories included in the package. Up to 190 supplier-listed potential detections are not fixed or guaranteed; the displayed reference list is under reconciliation.

Why homeowners choose it

When the question is about biological conditions in a water sample rather than a broad chemistry screen.

What results can help explain

The report can distinguish which biological indicators were included and provide a clearer starting point for next questions.

Search by category or parameter

Start with the grouped view. Select a parameter only when you want its background information.

About this reference listThe current supplier advertises up to 190 potential detections, but its published categories currently name 188 and do not reconcile to that number. This page retains a separate 129-entry reference list while the full roster is reconciled; it is not a guaranteed or complete detection list.
