Wisconsin Administrative Code › Department of Natural Resources › NR 800 - Environmental Protection - Water Supply › Chapter NR 809 - Safe Drinking Water › Subchapter V - Reporting, Consumer Confidence Reports and Record Keeping › Section NR 809.835 - Required additional health information for consumer confidence reports

Current through June 24, 2024
(1) ADDITIONAL HEALTH INFORMATION FOR
				  VULNERABLE POPULATIONS. All reports shall prominently display the following
				  language: "Some people may be more vulnerable to contaminants in drinking water
				  than the general population. Immuno-compromised persons such as persons with
				  cancer undergoing chemotherapy, persons who have undergone organ transplants,
				  people with HIV/AIDS or other immune system disorders, some elderly, and
				  infants can be particularly at risk from infections. These people should seek
				  advice about drinking water from their health care providers. EPA/CDC
				  guidelines on appropriate means to lessen the risk of infection by
				  Cryptosporidium and other microbial contaminants are available from the
				  environmental protection agency's safe drinking water hotline at
				  800-426-4791."
(2) ADDITIONAL
				  ARSENIC INFORMATION. Beginning July 1, 2002 a water supplier for a public water
				  system that detects arsenic above 0.005 mg/L and up to and including 0.01 mg/L:
(a) Shall include in the report a short
				  information statement about arsenic, using language such as: While your
				  drinking water meets EPA's standard for arsenic, it does contain low levels of
				  arsenic. EPA's standard balances the current understanding of arsenic's
				  possible health effects against the costs of removing arsenic from drinking
				  water. EPA 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) May write their own
				  educational statement, but only in consultation with the department.
