Title 22 { levels of nitrite in drinking Water have not been observed, other sources of nitrite have caused serious illness and sometimes death in infants under six months of age. The serious illness in infants is caused because nitrite interferes with the oxygen carrying capacity of the child's blood. This is an, acute disease in that symptoms can develop rapidly. However, in most cases, health deteriorates over a period of days. Symptoms include shortness of breath and blueness of the skin. Clearly, expert medical advice should be 'sought immediately if these symptoms occur. The purpose of this notice is to encourage parents and other responsible parties to provide infants with an alternate source of drinking water. Local and State health authorities are the best sources for information concerning alternate sources of drinking water for infants. DIAS has set the drinking water standard at 1 part per million (ppm) as nitrogen for"nitrite to protect against the risk of these adverse effeets. DIAS has also set a drinking water standard for nitrate (converted to nitrite in humans) at 10 ppm and for the swn of nitrate and nitrite at 10 ppm. Drinking water that meets the DHS standard is associated with little . to none of this risk and is considered safe with respect to nitrite." ; (n) Selenium: "The California Department of Health Services (DHS) sets drinking water`-j;. standards and has determined that selenium is a health concern at certain high levels of exposure. Selenium is also an essential nutrient at low levels otexposure. This inorganic chemical is found. naturally in food and soils and is used in electronics, photocopy operations, the manufacture of glass,': chemicals, drugs, and as a fungicide and a feed additive. In humans, exposure to high levels of F: selenium over a long period of time has resulted in a number of adverse health effects, including a loss of feeling and control in the arms and legs. DHS has set the drinking water standard for selenium at 0.05 part per million (ppm) to protect against the risk of these adverse health effects. Drinking water that meets the DHS standard is associated with little to none of this risk and is:; r considered safe with respect to selenium." (o) Thallium: "The California Department of Health Services (DIAS) sets drinking water ' - standards and has determined that thallium is a health concern at certain high levels of exposure. This a inorganic metal is fatind naturally in soils and is used in electronics, pharmaceuticals, and the manufacture of glass and alloys. This chemical has been shown to damage the kidney, liver, brain and intestines of laboratory animals when the animals are exposed at high levels over their lifetimes. MIS has set the drinking water standard for thallium at 0.002 part per million (ppm) to protect ." ' against the risk.of these adverse health effects. Drinking water which meets the DIIS standard is associated with little to none of this risk and should be considered safe with respect to thallium." Section 64468.2. IIealth Effects Language - Volatile Organic Chemicals Pursuant to Section 64467, the explanation of potential adverse health effects for volatile organic 'Y chemicals shall include the following mandatory language for the designated contaminants: (a) Benzene'. "The California Department of Health 'Services (DHS) sets drinking water standards and has detertnihed that benzene is a health concern at certain levels of exposure. This chemical is used as a solvent and degreaser of metals. It is also a major component of gasoline. 246
