Compare Water Quality

Our water quality comparison tool lets you see side-by-side differences between any two US cities. Each comparison includes:

• Overall Safety Scores - Letter grades from A+ to F based on EPA data
• Contaminant Levels - Detailed breakdown of all detected contaminants with percent of EPA limits
• Compliance Records - EPA violation history and resolution status
• Infrastructure Quality - Age and condition of water systems
• Key Differences - Which city has better water in each category
• Filter Recommendations - Suggested water filtration based on each city's specific contaminants

All data is sourced from the EPA's Safe Drinking Water Information System (SDWIS) and updated quarterly.
