1,1-Dichloro-2-Propanone is an organic chemical formed during water chlorination. It's also used as an industrial solvent and can enter water from factory discharges.

1,1-Dichloro-2-Propanone is primarily a byproduct of water chlorination, formed when chlorine reacts with organic matter in water. It's also used in industrial processes as a solvent. This compound can be detected in water using gas chromatography-mass spectrometry (GC-MS) techniques. While it's not typically found in high concentrations in drinking water, its presence is monitored due to potential health concerns. The EPA and other regulatory bodies continue to study its effects and establish safe exposure limits.
