SALINA, Kan. (AP) — Health officials say only about half of the 33 cases of elevated lead levels reported in Saline County children were investigated because some people were reluctant to allow officials into their homes. Saline County official Shawn Esterl, who helped the Kansas Department of Health and Environment with the investigations, said other parents didn't like the information they were given by health officials. The Salina Journal reports that the families who didn't participate will not receive specific information about the source of lead in their homes but can still follow general recommendations for controlling lead hazards. The state began an investigation in June because of the high number of children affected. In August, the state notified families that no single cause for the elevated lead levels was found.
