cis-1,2-Dichloroethylene
Wernersville Muni Water Authority
NOTE: Wernersville Muni Water Authority purchases water from Western Berks Water Authority which is required to test for cis-1,2-dichloroethylene. Sample information shown below was taken by Western Berks Water Authority.
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.
