The presence of vinyl chloride in drinking water can be a problem for some people living in certain areas of the country. Vinyl chloride (VC) is colorless, organic gas that has a sweet odor to it. The reason this substance may be a problem for certain areas of the country is in its many uses.
Vinyl chloride is widely used in the manufacturing and processing of numerous products. These products can run from those used in construction to the automotive industry. VC is also used in the manufacturing of piping, electrical wire insulation, cables, industrial equipment, various household devices, rubber, glass, medical supplies, and paper. And this is not a complete list!
Vinyl chloride normally gets into water sources through leaching from polyvinyl chloride (PVC) piping as well as from discharges from industries and manufacturing factories.
Those who may be consuming VC in their drinking water for long periods of time may be at risk for cancers of various types. It is for this reason that the EPA has set up limits for this chemical in water.
The EPA has established the maximum contaminant level (MCL) for vinyl chloride at 0.002 mg/L or 2 ppb (parts per billion).
Some states, especially those with heavy industry, have set higher standards for this substance and those standards override the EPA level.
For those who get their drinking water from municipal treatment plants, testing for VC is conducted on a periodic basis. In the event the testing reveals levels of VC that are higher than the limit set by the EPA, the water supplier must notify customers within 30 days of discovering the violation, and they must also take immediate steps to correct the problem.
The presence of vinyl chloride can also be a problem for those who get their water from private wells. Private well water does not have to be monitored by the state or anyone else for that matter. However, homeowners who ingest well water should conduct their own testing for VC if they are in an area where leaching or run off may occur. Testing should also be conducted if PVC piping is used to a great extent in the plumbing of the well and its distribution lines.
In-home water filters that provide some form of aeration are the most effective in removing VC from water.
