Glyoxal
Status: Unregulated - EPA has not established a maximum legal limit in tapwater for this contaminant.
Glyoxal is a synthetic chemical used for production of paper coatings, textiles and polymers and as an intermediate for making other chemicals; it is used as a disinfectant in medicine and may form as a byproduct of tap water ozonation.
