See recommended water filters →What is in the water

DetectedIndustrial contaminant. Known human carcinogen. Unregulated at the federal level in the US.
EWG lists chromium-6 among detected large-system contaminants for Wichita.
Nitrates
DetectedCommon in agricultural areas from fertiliser runoff. Particularly dangerous for infants.
