The Hidden Truth
What you don't know can hurt you
Regulatory Gaps
Utilities may test for toxins just once a year. Contaminants can spike between tests, exposing your family for months.
The Last Mile
Your utility tests water at the plant. Lead and copper can be picked up in the pipes between the plant and your tap.

Water utilities test the water leaving their treatment plant, not the water coming out of your tap. By the time water travels through distribution pipes to your home, it can pick up lead from older pipes and fittings, chlorination byproducts, and other contaminants not present when it left the plant.
Utilities are also only required to test for a subset of regulated contaminants on a fixed schedule, sometimes as infrequently as once a year for certain parameters. A KELP home water test gives you an address-specific result from your own tap, not a system-wide average.
Your annual utility report (Consumer Confidence Report) is public, but it tests at the plant, uses averages across thousands of customers, and typically lags by 6–12 months. Your home test kit tells you what's actually in your water, today.
