Benchmark Labs collects water samples for potability, which is required on all properties that utilize wells, cisterns, or springs before a real estate closing. Some FHA lenders require water to be tested for Lead, Nitrate and Nitrite. Check with you lender.

Benchmark Labs is an Ohio EPA certified laboratory. Lab results are normally reported within 24 hours. We also offer well chlorination and water retesting for samples that do not pass the analysis.

Ohio EPA Result Interpretation:

TC Negative = Free from Coliform bacteria Passed
TC Positive = Coliform bacteria present Failed

A failed water test can normally be remedied by chlorinating the water supply source.

We also offer a Complete Water Check (CWC) for owners who desire a more extensive evaluation of their water source. The CWC tests for 97 different items, including pesticides, herbicides and metals. This test can take up to 15 days to complete.
