Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) A system that detects arsenic at levels
				  above 0.005 mg/L, but below or equal to the MCL, shall include the following in
				  its Consumer Confidence Report: "While your drinking water meets the federal
				  and state standard for arsenic, it does contain low levels of arsenic. The
				  arsenic standard balances the current understanding of arsenic's possible
				  health effects against the costs of removing arsenic from drinking water. The
				  U.S. Environmental Protection Agency continues to research the health effects
				  of low levels of arsenic, which is a mineral known to cause cancer in humans at
				  high concentrations and is linked to other health effects such as skin damage
				  and circulatory problems."
(b) A
				  system that detects nitrate at levels above 5 mg/L (as nitrogen), but below the
				  MCL, shall include the following in its Consumer Confidence Report: "Nitrate in
				  drinking water at levels above 10 mg/L is a health risk for infants of less
				  than six months of age. Such nitrate levels in drinking water can interfere
				  with the capacity of the infant's blood to carry oxygen, resulting in a serious
				  illness; symptoms include shortness of breath and blueness of the skin. Nitrate
				  levels above 10 mg/L may also affect the ability of the blood to carry oxygen
				  in other individuals, such as pregnant women and those with certain specific
				  enzyme deficiencies. If you are caring for an infant, or you are pregnant, you
				  should ask advice from your health care provider." If a system cannot
				  demonstrate to the State Board with at least five years of the most current
				  monitoring data that its nitrate levels are stable, it shall also add the
				  following language to the preceding statement on nitrate: "Nitrate levels may
				  rise quickly for short periods of time because of rainfall or agricultural
				  activity."
(c) A system that
				  detects lead above the action level in more than 5%, and up to and including
				  10%, of sites sampled, shall include the following in its Consumer Confidence
				  Report: "Infants and young children are typically more vulnerable to lead in
				  drinking water than the general population. It is possible that lead levels at
				  your home may be higher than at other homes in the community as a result of
				  materials used in your home's plumbing. If you are concerned about elevated
				  lead levels in your home's water, you may wish to have your water tested and/or
				  flush your tap for 30 seconds to 2 minutes before using tap water. Additional
				  information is available from the USEPA Safe Drinking Water Hotline
				  (1-800-426-4791)."
