The Wisconsin Department of Natural Resources regulates the amount of chloroform that can be released into outdoor ambient air by industries. The state groundwater standard for chloroform is 6 parts per billion ppb. The state and federal drinking water standard for total trihalomethanes in chlorinated, municipal drinking water supplies is ppb.
We suggest you stop drinking water that contains more than the standard for your water supply. If levels of chloroform or trihalomethanes are very high in your water, you may also need to avoid washing, bathing, or using the water for other purposes. A person's reaction to chemicals depends on several things, including individual health, heredity, previous exposure to chemicals including medicines, and personal habits such as smoking or drinking.
Immediately or shortly after exposure to a level of ppm , ppbv of chloroform in air, a person may feel tired, dizzy, and have a headache. Chloroform can be measured in exhaled breath, urine, blood, and other tissues, but no reliable method exists to determine the level of your exposure.
Because chloroform can be formed in the body following exposure to other substances, levels found in tests cannot always be linked to just chloroform exposure. Doctors can use tests of liver, kidney, and heart function to evaluate the health effects of chloroform exposure.

There are at least pollutants found in the drinking water, but the EPA is required to set standards for only about sixty of them, and these standards are routinely violated without consequence. Out of the , violations, the states took just over 2, enforcement actions, while the EPA took about Municipalities struggle with outdated technology.
Over 70, different chemical compounds are now in use by industry, agriculture, and private citizens, with 5, new and unproven chemical compounds being added into the environment each year.
That amounts to 18 billion pounds of new pollutants every year. So what is chloroform? Chloroform is also known as trichloromethane, methane chloride, or methyl trichloride. It is a colorless liquid with a pleasant, non-irritating odor and slightly sweet taste. Most of the chloroform found in the environment comes from the industry. It will only burn when it reaches very high temperatures. Chloroform was one of the first inhaled anesthetics to be used during surgery, but it is not used for anesthesia today.
Nearly all the chloroform made in the United States today is used to make other chemicals, but some is sold or traded to other countries. We also import chloroform. Chloroform enters the environment from chemical companies, paper mills, wastewater from sewage treatment plants, and drinking water that contains chlorine. Chloroform can enter the air directly from factories that make or use it, and by evaporating from water and soil that contain it.
If you work in an industry that uses chloroform, please read chemical labels and the accompanying Safety Data Sheets for hazard information. The following resources provide information about occupational exposure to chloroform. Search the HHE database for more information on chemical topics.

Overview CAS No. Some examples of workers at risk of being exposed to chloroform include the following: Workers involved in paper manufacture or recycle industries Service employees exposed to some air conditioner refrigerants Equipment operators working at sanitary landfills Workers who work in water treatment plants NIOSH recommends that employers use Hierarchy of Controls to prevent injuries.
