Title 22 <br /> 1/93 <br />Section 64468. Health Effects Language <br />The description of potential adverse health effects shall <br />include the following mandatory language for the designated <br />contaminants: <br />For TrichloroethYlene. "The California Department of <br />Health Services (DHS) sets drinking water standards and has <br />determined that trichloroethylene is a health concern at certain <br />levels of exposure. This chemical is a common metal cleaning and <br />dry cleaning fluid. It generally gets into drinking water by <br />improper waste disposal. This chemical has been shown to cause <br />cancer in laboratory animals such as rats and mice when the animals <br />are exposed at high levels over their lifetimes. Chemicals that <br />cause cancer in laboratory animals also may increase the risk of <br />cancer in humans who are exposed at lower levels over long periods <br />of time. DHS has set forth the enforceable drinking water standard <br />for trichloroethylene at 0.005 parts per million (ppm) to reduce the <br />risk of cancer or other adverse health effects which have been <br />observed in laboratory animals. Drinking water which meets this <br />standard is associated with little to none of this risk and should <br />be considered safe." <br />For Carbon tetrachloride. "The California Department of <br />Health Services (DHS) sets drinking water standards and has <br />determined that carbon tetrachloride is a health concern at certain <br />levels of exposure. This chemical was once a popular household <br />cleaning fluid. It generally gets into drinking water by improper <br />waste disposal. This chemical has been shown to cause cancer in <br />laboratory animals such as rats and mice when the animals are <br />exposed at high levels over their lifetimes. Chemicals that cause <br />cancer in laboratory animals also may increase the risk of cancer in <br />humans who are exposed at lower levels over long periods of time. <br />DHS has set the enforceable drinking water standard for carbon <br />tetrachloride at 0.0005 part per million (ppm) to reduce the risk of <br />cancer or other adverse health effects which have been observed in <br />laboratory animals. Drinking water which meets this standard is <br />associated with little to none of this risk and should be considered <br />safe." <br />For 1,2-Dichloroethane. "The California Department of <br />Health Services (DHS) sets drinking water standards and has <br />determined that 1,2-dichloroethane is a health concern at certain <br />levels of exposure. This chemical is used as a cleaning fluid for <br />fats, oils, waxes, and resins. It generally gets into drinking water <br />from improper waste disposal. This chemical has been shown to cause <br />cancer in laboratory animals such as rats and mice when the animals <br />are exposed at high levels over their lifetimes. <br />Chemicals that cause cancer in laboratory animals also may increase <br />161
