Common questions

Are home water testing kits accurate?
DIY strip tests give a useful snapshot but are less precise than lab analysis. For definitive results, send a sample to an ISO 17025 accredited lab like Tap Score.
What should I test my water for?
At minimum, test for hardness, pH, chlorine, lead, and nitrates. If you are concerned about PFAS or microplastics, you will need a lab test as strip kits cannot detect these.
