To detail baseline drinking water sample lead concentrations and features of US state-level programs and policies to test school drinking water for lead in 7 states' operating programs between 2016 and 2018. We coded program and policy documents using structured content analysis protocols and analyzed state-provided data on lead concentration in drinking water samples collected in public schools during initial testing phases. We analyzed data from 5688 public schools, representing 35% of eligible schools in 7 states. The number of samples per school varied. The proportion of schools identifying any sample lead concentration exceeding 5 parts per billion varied (13%-81%). Four states exceeded 20%. Other program features varied among states. Instances of lead above the state action level were identified in all states. In 2018, many US public school students attended schools in states without drinking water lead-testing programs. Testing all drinking water sources may be recommended. Initiating uniform school drinking water lead testing programs and surveillance over time could be used to reduce risk of lead exposure in drinking water.

Introduction: Contamination of drinking water by can cause serious diseases, including cancer. The determinants of the infection rate are socioeconomic status, low standard of living and overcrowding. In addition, exposure to environmental sources contaminated with feces, such as water and vegetables, is another risk factor for infection.

African communities that have been forced to leave their homes experience a considerably greater susceptibility to malaria as a result of densely populated living conditions, restricted availability of healthcare, and environmental influences. Internally displaced individuals frequently live in large settlements with restricted availability to drinking water, essential sanitation, and medical services, intensifying the spread of malaria. As a result, the occurrence of malaria is significantly more common among refugees and internally displaced individuals compared to those who are not displaced.
