Vinyl chloride
EPA Designation Regulated
EPA Classification Organic Chemicals
EPA Levels 1,2 zero MCLG (mg/L)
0.002 MCLG (mg/L)
Alternative Names none
Sources Leaching from PVC pipes; discharge from plastic factories
Vinyl chloride is a chemical used for production of PVC plastic; it contaminates drinking water due to leaching from PVC pipes and discharges from plastics manufacturing.

Overview

Vinyl chloride is a colorless organic gas with a sweet odor.

Uses

Vinyl chloride is used in the manufacture of numerous products in building construction, automotive industry, electrical wire insulation and cables, piping, industrial and household equipment, medical supplies, and is depended upon heavily by the rubber, paper, and glass industries.

Health Effects

Some people who drink water containing vinyl chloride well in excess of the maximum contaminant level (MCL) for many years may have an increased risk of cancer.

EPA Definitions:

1Maximum Contaminant Level Goal (MCLG) - The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety and are non-enforceable public health goals.

Maximum Contaminant Level (MCL) - The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to MCLGs as feasible using the best available treatment technology and taking cost into consideration. MCLs are enforceable standards.

Maximum Residual Disinfectant Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

(TT) Treatment Technique - A required process intended to reduce the level of a contaminant in drinking water.

Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

2 Units are in milligrams per liter (mg/L) unless otherwise noted. Milligrams per liter are equivalent to parts per million.
