cis-1,2-Dichloroethylene
Lawco Mansura
NOTE: Lawco Mansura purchases water from Avoyelles Water Commission which is required to test for cis-1,2-dichloroethylene. Sample information shown below was taken by Avoyelles Water Commission.
1,2-Dichloroethylene, a neurotoxic solvent, exists in two different forms: trans-1,2-dichloroethylene and cis-1,2-dichloroethylene. A mixture of the two forms is used to manufacture other solvents and chemical products.
