cis 1,2 Dichloroethylene
Cis-1,2-xichloroethylene (cis-1,2-DCE) is one of two isomers of the volatile organic chemical 1,2-dichloroethylene. It is readily volatile, thus all routes of exposure (ingestion, inhalation and dermal) are relevant if one is exposed via drinking water. The other isomer, trans-1,2-DCE, is used as a solvent in industrial processing and for extracting meat and fish oils, but cis-1,2-DCE is not currently used in industry. It has been detected in both surface water and groundwater.

Health Effects
Drinking water standards for cis-1,2-DCE are based on potential kidney effects.
Affected Organs & Systems:
Common Sources
- Although it is not currently produced or used in the US, cis-1,2-DCE may enter the environment and drinking water sources through the breakdown of common chlorinated solvents. These include tri- and tetrachloroethylene.
How to Remove It
Water filters certified under the following NSF standards are effective at removing cis 1,2 Dichloroethylene:
EPA MCLG Level
The EPA MCLG represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
