1

Chicago has over 400,000 lead service lines -- among the most in any US city.

2

The city uses chloramine instead of chlorine, which forms NDMA and other DBPs.

3

Lead leaches from pipes directly into tap water, especially in older homes.

COMMON QUESTIONS
Is Chicago tap water safe to drink?

Chicago water meets EPA legal standards but meeting standards is not the same as being free of contaminants. EPA limits are set based on feasibility, not always on what is safest for health. Enter your ZIP above to see the full violation history and PFAS data for your specific water system.

Do I need a water filter?

Even compliant water can contain contaminants at levels above what independent health scientists consider safe -- particularly for PFAS, lead, and chromium-6. An EPA-certified RO system removes 95-99% of all detected contaminants and costs $0.10-$0.25 per gallon, compared to $1-$3 for bottled water.

What's the best filter for this area?

For most US cities, a reverse osmosis system under the sink is the gold standard -- it removes lead, PFAS, arsenic, nitrates, fluoride, and virtually everything else. For renters, a Waterdrop D4 countertop RO requires zero installation. Enter your ZIP above to get personalized recommendations based on your actual water report.
