Former Occidental Chemical

Property owners notified: 30. Date notified: Sept. 17, 2003

Contaminants:

Tetrachloroethylene (PCE). Also known as tetrachloroethene, perchloroethylene and PCE.
A manufactured chemical widely used for dry cleaning of fabrics and for metal-degreasing. It is also used to make other chemicals and is used in some consumer products.

Possible dangers: reasonably be anticipated to be a carcinogen

Carbon tetrachloride. A manufactured chemical that does not occur naturally. It is a clear liquid with a sweet smell that can be detected at low levels. It is also called carbon chloride, methane tetrachloride, perchloromethane, tetrachloroethane, or benziform. Most often found in the air as a colorless gas. It is not flammable and does not dissolve in water very easily. It was used in the production of refrigeration fluid and propellants for aerosol cans, as a pesticide, as a cleaning fluid and degreasing agent, in fire extinguishers, and in spot removers. Because of its harmful effects, these uses are now banned and it is only used in some industrial applications.

Possible dangers: EPA says probable human carcinogen.

Hexachlorobutadiene. Does not occur naturally in the environment. It is formed during the processing of other chemicals such as tetrachloroethylene, trichloroethylene, and carbon tetrachloride. Hexachlorobutadiene is an intermediate in the manufacture of rubber compounds and lubricants. It is used as a fluid for gyroscopes, a heat transfer liquid, or a hydraulic fluid.

Possible dangers: possible human carcinogen.

Hexachloroethane. In the U.S., about half of the hexachloroethane is used by the military for smoke-producing devices. It is also sold as degassing pellets used to remove air bubbles in melted aluminum. Hexachloroethane may be present as an ingredient in some fungicides, insecticides, lubricants, plastics, and cellulose. At one time, hexachloroethane was prescribed for deworming animals. Hexachloroethane is no longer made in the U.S., but it is formed as a by-product in the production of some chemicals.

Possible dangers: Possible human carcinogen.

Trans-1,2-dichloroethylene. An odorless organic liquid that has two slightly different forms, a "cis" form and a "trans" form. Both the cis and trans forms - usually as a mixture - are used as a solvent for waxes and resins; in the extraction of rubber; as a refrigerant; in the manufacture of pharmaceuticals and artificial pearls; in the extraction of oils and fats from fish and meat; and in making other organics.

Possible dangers: EPA has found cis- and trans-1,2-DCE to potentially cause central nervous system depression when people are exposed to it at unsafe levels for relatively short periods of time. Both cis- and trans-1,2-DCE can cause liver, circulatory and nervous system damage from long-term exposure at unsafe levels. The trans form is approximately twice as potent as the cis form in its ability to depress the central nervous system.

Hexachlorocyclopentadiene. A manufactured chemical that does not occur naturally. It is a light, lemon-yellow liquid with a sharp musty odor. It easily evaporates into the air; the vapor looks like a blue haze. HCCPD is used in the manufacture of certain pesticides. Most of the HCCPD in the environment results from releases during production and disposal. It is also used to make flame retardants, resins that won't burn, shock-proof plastics, esters, ketones, fluorocarbons, and dyes.

Possible dangers: No information to show it causes cancer.

Hexachlorobenzene. Was widely used as a pesticide to protect the seeds of onions and sorghum, wheat, and other grains against fungus until 1965. It was also used to make fireworks, ammunition, and synthetic rubber. Currently, there are no commercial uses of hexachlorobenzene in the U.S.

Possible dangers: Reasonably expected to cause cancer. A study of people in Turkey who ate bread accidentally contaminated with hexachlorobenzene showed that the young children of mothers who it ate it or young children who ate it themselves can have lower survival rates.
