130A-131.9A. Investigation to identify lead poisoning hazards.

(a) When the Department learns of confirmed lead poisoning, the Department shall conduct an investigation to identify the lead poisoning hazards to children and pregnant women. The Department shall investigate the residential housing unit where the child or pregnant woman with confirmed lead poisoning resides. The Department shall also investigate the supplemental addresses of the child or pregnant woman who has confirmed lead poisoning.

(a1) When the Department learns of an elevated blood lead level, the Department shall, upon informed consent, investigate the residential housing unit where the child or pregnant woman with the elevated blood level resides. When consent to investigate is denied, the child or pregnant woman with the elevated blood lead level cannot be located, or the child's parent or guardian fails to respond, the Department shall document the denial of consent, inability to locate, or failure to respond.

(b) The Department shall also conduct an investigation when it reasonably suspects that a lead poisoning hazard to children or pregnant women exists in a residential housing unit or child-occupied facility occupied, regularly visited, or attended by a child less than six years of age or a pregnant woman.

(c) In conducting an investigation, the Department may take samples of surface materials, or other materials suspected of containing lead, for analysis and testing. If samples are taken, chemical determination of the lead content of the samples shall be by atomic absorption spectroscopy or equivalent methods approved by the Department.
