Dichloroethylene
Dichloroethene -- Dichloroethene has been used in the production of chlorinated solvents, the extraction of rubber, to remove fats from meat and fish and to decaffeinate coffee. It is a natural byproduct of PCE. The chemical can act as an anesthetic resulting in nervous system depression. It can also lead to liver damage in high concentrations. 1,1-Dichloroethylene (1,1-DCE) is an organic liquid with a mild, sweet, chloroform-like odor. Virtually all of Here are some common trade names: 1,1-DCE |

| "The MCL has been set at 7 ppb because EPA believes, given present technology and resources, this is the lowest level to which water systems can reasonably be required to remove this contaminant should it occur in drinking water." |

The main health effect is liver damage. Also, kidney damage, toxicity to the developing fetus and cancer. Removal: The following treatment method(s) have proven to be effective for removing 1,1-dichloroethylene to below 0.007 mg/L or 7 ppb: Granular activated carbon in combination with packed tower aeration. Reverse osmosis reduces dichloroethylene by about 85%. Main Source: EPA at http://www.epa.gov/ogwdw/pdfs/factsheets/voc/11-dichl.pdf |
