Is free water testing accurate?

A professional free water test can accurately measure the water quality indicators included in that test. It is a useful first step for identifying problems such as hardness, iron, manganese, chlorine, pH imbalance, and elevated total dissolved solids.

It is not automatically a complete health or regulatory analysis. No single quick test checks for every possible contaminant. Suspected bacteria, PFAS, lead, or other health-related concerns may require samples to be analyzed by a state-certified laboratory. Long Island Clean Water Service will explain what the free test covers and whether additional testing makes sense, so you know exactly what the results tell you.
