cis-1,2-Dichloroethylene
Vista De Manana
NOTE: Vista De Manana purchases water from Entranosa Water and Wastewater Co-op which is required to test for cis-1,2-dichloroethylene. Sample information shown below was taken by Entranosa Water and Wastewater Co-op.
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.
