## About

TapWaterMap shows US tap-water quality city by city, using the EPA's own Safe Drinking Water Information System (SDWIS) records. Look up the water systems serving a city, the contaminants and violations on record — with dates and whether the EPA classifies each as health-based — compare cities side by side, and understand what any contaminant is. It's calm and sourced: it reports what the EPA recorded and never gives a safety verdict. Covers about 19,000 cities across all 50 states and DC.

## How to use

1. **Add it in ChatGPT** Open TapWaterMap in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick TapWaterMap, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.
