cis-1,2-Dichloroethylene
Aqua Illinois-university Park
NOTE: Aqua Illinois-university Park purchases water from Aqua Illinois - Kankakee which is required to test for cis-1,2-dichloroethylene. Sample information shown below was taken by Aqua Illinois - Kankakee.
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.
