We cover approximately 13,592 cities tied to active Community Water Systems and Non-Transient Non-Community systems in SDWIS. Some very small communities or unincorporated areas may not be listed if they don't appear in SDWIS geographic records. Let us know and we'll look into it.
Our underlying data is public EPA data. You're welcome to reference MyWaterIQ in articles or research. For bulk data requests or partnerships, email us.
