Water Testing: Complete Guide

You can't filter what you don't measure — and you can't trust that your Consumer Confidence Report tells the whole story. Your utility's annual report shows contaminant levels at the treatment plant, not at your tap. Lead leaches from pipes after treatment. PFAS is rarely tested by utilities. Well water has no oversight at all. These guides walk you through every testing option — from free CCR lookups to certified lab panels — so you know exactly what's in your water before choosing a filter.
