Iowa Water Systems

Iowa

1,765 community water systems on record — 1,078 active, 687 inactive.

Every active community water system nationwide must produce a Consumer Confidence Report under the EPA's revised rule, effective for reports due July 1, 2027.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed July 4, 2026. This is a record-keeping and public-information tool — it does not replace Iowa’s official records. Always confirm current status with Iowa before making decisions based on this information.
