cis-1,2-Dichloroethylene
Santa Claus Water Utility
NOTE: Santa Claus Water Utility purchases water from Patoka Lake Regional Water which is required to test for cis-1,2-dichloroethylene. Sample information shown below was taken by Patoka Lake Regional Water.
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.
