Arsenic vs. guideline

82x

Chromium vs. guideline

Bottom line: 8 contaminants came back above the latest health guidelines — led by arsenic, farm-runoff nitrate and chlorination byproducts. The good news: the right system reduces all of them.

Detected above health-based guidelines

Level found vs. a non-enforceable, health-based guideline. Detection data comes from public Iowa DNR & U.S. EPA testing records (2021–2023); health guidelines are drawn from state public-health authorities (such as California's OEHHA) and peer-reviewed research, and are far stricter than federal legal limits. Water that exceeds a health guideline can still meet all legal standards.

Based on publicly available drinking-water testing data from the Iowa Department of Natural Resources and the U.S. Environmental Protection Agency (detections 2021–2023; radiologicals 2018–2023). Levels are utility-wide annual averages and meet federal legal limits; 'health-based guideline' refers to non-enforceable health goals set by federal or state public-health authorities. 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.
