The presence of lead (Pb) in drinking water can lead to severe health effects of which include the hindrance of brain development in children. As a result, proper testing of drinking water in schools is imperative for students’ health. For our research this semester we are investigating Pb levels in drinking water Middlebury Union High School. This research includes three main components. The first is creating a comprehensive approach to developing a sampling and testing plan that can be replicated at other schools in the future. If we do encounter unsafe levels of lead, it is critical that our data is reliable and follows on the approved sampling protocol of the EPA. After carrying out the sample collections, we will determine the concentration of lead using graphite furnace atomic absorption spectroscopy, which includes accuracy and quality control assessments. Once complete, we will present our results to the community, likely including the school board and possibly students and parents. The EPA sites the lead action level of 15 parts per billion in drinking water. Therefore, if a sample contains a concentration at or above this level, we will share this information with the school staff so that they can address the problem and make the necessary changes to reduce the lead concentrations. The methods we develop in this project, both related to sampling and communicating results with the school community, will be applicable and hopefully enacted in other schools.
