OBJECTIVE: On November 20, 2021, petroleum fuel contaminated the Red Hill well, which provides water to about 93 000 persons on Oahu, Hawaii. Initial investigations recommended further evaluations of long-term health effects of petroleum exposure in drinking water. We reviewed electronic health records of those potentially exposed to contaminated water to understand prevalence of conditions and symptoms. METHODS: A sample of persons potentially exposed during November 20, 2021-March 18, 2022 who sought care within the military health system through February 24, 2023 was identified. Abstracted records were categorized as worsening preexisting or persistent new for conditions and symptoms. RESULTS: Of 653 medical charts reviewed, 357 (55%) had worsening preexisting or persistent new conditions or symptoms. Most-documented conditions included worsening preexisting migraine (8%; 50/653) and chronic pain (4%; 26/653), and persistent new migraine (2%; 14/653) and adjustment disorder (2%; 13/653). Most-documented symptoms included worsening preexisting headache (8%; 49/653) and anxiety (6%; 42/653), and persistent new rash (7%; 46/653) and headache (5%; 34/653). CONCLUSIONS: Approximately half of the abstracted medical records demonstrated worsening preexisting or persistent new conditions or symptoms and might benefit from sustained access to physical, mental, and specialized health care support systems. Continued monitoring for long-term health outcomes is recommended.

Introduction: Motor-vehicle crashes are a leading cause of death among children in the United States, and almost one-fourth of all trips by school-aged children are trips to and from school. This study sought to determine how children (5-18. years) travel to and from school and, among those living ≤ 1. mile of school, to explore the role of school bus service eligibility on school travel mode. Methods: We used national 2012 survey data to determine prevalence of usual school travel mode, stratified by distance from school. For those living ≤ 1. mile of school, multivariable regression was conducted to assess the association between bus service eligibility and walking or bicycling. Results: Almost half (46.6%) of all children rode in passenger vehicles (PV) to school and 41.8% did so for the trip home. Results were similar among those living ≤ 1. mile (48.1%, PV to school; 41.3%, PV to home). Among those living ≤ 1. mile, 21.9% and 28.4% of children walked or bicycled to and from school, respectively. Ineligibility for school bus service was strongly associated with walking or bicycling to school [adjusted prevalence ratio (aPR: 5.36; p. < 0.001)] and from school (aPR: 5.36; p. < 0.001). Conclusions: Regardless of distance from school, passenger vehicles were a common mode of travel. For children who live close to school, the role that school bus service eligibility plays in walking or bicycling deserves further consideration. Practical applications: Given the large proportion of children who use passenger vehicles for school travel, effective interventions can be adopted to increase proper child restraint and seat belt use and reduce crash risks among teen drivers. Better understanding of conditions under which bus service is offered to children who live close to school could inform efforts to improve pedestrian and bicyclist safety for school travel.
