Compiled from the EWG Tap Water Database, which aggregates the testing results utilities report to state agencies and the U.S. Environmental Protection Agency (detections 2014-2023). Official Iowa records are published by the Iowa Department of Natural Resources. Levels are utility-wide averages and meet federal legal limits; 'health-based guideline' means EWG's own health guideline, which is not enforceable and is stricter than the federal legal limit. Informational only — not a medical or safety determination. Your home's water, especially on a private well, may differ; a free in-home test measures your actual water.
