In small towns like Morris that are surrounded by agriculture, there’s an increased likelihood of contaminants to be present in the water. These commonly include heavy metals and pesticides which, in high enough dosages or prolonged exposure, can quickly become poisonous and harmful with lasting effects for both plants and humans. Throughout our research we have been analyzing the presence, if any, of lead, copper and cadmium as well as the common pesticides atrazine and mesotrione in the water throughout Morris. We look at a variety of samples coming from melted snow (collected throughout Nov. 2022–Apr. 2023), drinking water, and the Pomme de Terre River as well as the lake that feeds it. Our methods of detection include high performance liquid chromatography and various electrochemical techniques including linear sweep voltammetry, cyclic voltammetry, and square-wave voltammetry. We hope to then compare our data to the regulations and guidelines set by the Environmental Protection Agency and ensure that they fall below there commended values for human consumption.
