## What is TapGrade?

TapGrade is a drinking water quality monitor that pulls official EPA violation data to give you an instant A-F safety grade for any community water system in the U.S. Just enter a ZIP code. No subscription — one-time purchase unlocks everything.

INSTANT WATER GRADES
Enter any U.S. ZIP code and get a clear A-F letter grade based on your water system's EPA compliance history. TapGrade analyzes the last 10 years of health-based violations, weighing recent issues more heavily and flagging active, unresolved problems. See exactly why your water got the grade it did — every deduction is explained in plain English.

5-YEAR GRADE TREND
Track how your water system's safety record has changed over time with an interactive trend chart. See whether things are getting better, worse, or holding steady.

CONTAMINANT BREAKDOWN
See which contaminants triggered violations, how measured levels compare to EPA Maximum Contaminant Levels (MCLs), and what each contaminant means for your health. Tap any contaminant for a detailed breakdown — health effects, MCL comparison, and recommended filter types. Free users see the top 3 contaminants; premium unlocks the full list.

FULL VIOLATION HISTORY (PREMIUM)
Dive into the complete chronological record of every violation on file — including category, compliance dates, and open/resolved status. Tap any violation to see the full record: measured values vs. EPA limits, severity score, public notification tier, and timeline.

LEAD & COPPER RESULTS (PREMIUM)
View 90th-percentile Lead and Copper Rule sampling results with clear comparison to EPA action levels. Know if your water system has elevated lead or copper.

ENFORCEMENT ACTIONS (PREMIUM)
See formal EPA enforcement actions taken against your water system — state and federal orders, consent agreements, and compliance follow-ups. Understand the regulatory history beyond just violations.

FILTER RECOMMENDATIONS (PREMIUM)
Based on the specific contaminants detected in your water, TapGrade recommends the right filter types — Reverse Osmosis, Activated Carbon, Ion Exchange, UV Disinfection, and more. Shop for recommended filters directly from the app.

FULL REPORT (PREMIUM)
A dedicated tabbed report view with five sections: Overview, Contaminants, Violations, Lead & Copper, and Filters. Everything in one place for a complete picture of your water quality.

SAVED LOCATIONS (PREMIUM)
Save multiple locations — home, office, vacation home — and check each one's water quality with a single tap. Enable push notifications to get alerted when new health-based violations are detected.

PDF WATER REPORT (PREMIUM)
