cis-1,2-Dichloroethylene
Lake Bruin Water District #1
NOTE: Lake Bruin Water District #1 purchases water from Tensas Water District Association which is required to test for cis-1,2-dichloroethylene. Sample information shown below was taken by Tensas Water District Association.
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.
