cis-1,2-Dichloroethylene
The Village of Bald Head Island
NOTE: The Village of Bald Head Island purchases water from Brunswick County Water System which is required to test for cis-1,2-dichloroethylene. Sample information shown below was taken by Brunswick County Water System.
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.
