High chloroform in water
WebChloroform and Drinking Water Summary Chloroform (also called trichloro methane) is a chemical used to make other chemicals and a byproduct of chlorinating water. … WebChloroform also dissolves easily in water, but does not stick to the soil very well. This means that it can travel down through the soil to groundwater where it can enter a water supply. Chloroform lasts for a long time in both the air and in the groundwater. Most chloroform in the air eventually breaks down, but this process is slow.
