Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

The following is a list of chemicals published as a requirement of Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as California Proposition 65, that are "known to the state to cause cancer or reproductive toxicity" as of January 3, 2020. [1]
Section 304(a)(1) of the Clean Water Act is the Water Quality Criteria (WQC) developed for the protection of aquatic life and human health. [4] The MATC and ACR are used in a sequence of calculations to obtain the Criterion Maximum Concentration and Criterion Continuous Concentration (CMC and CCC, respectively) for the chemicals being regulated.
According to the EPA, methylene chloride is known to cause a range of cancers, as well as neurotoxicity and liver damage, while direct exposure can lead to death. The agency has reported that at ...
Maximum contaminant levels (MCLs) are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality. [1] [2] An MCL is the legal threshold limit on the amount of a substance that is allowed in public water systems under the Safe Drinking Water Act (SDWA).
Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
Chloroform, [10] or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent.It is a volatile, colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE. [11]
