Abstract - The electrocoagulation process has garnered
may include improved wastewater treatment processes, enhanced monitoring programs, regulatory actions to limit the use of certain chemicals, and public education campaigns to promote responsible disposal of pharmaceuticals and personal care products. Addressing emerging contaminants in water requires a multidisciplinary approach involving collaboration between scientists, policymakers, industry stakeholders, and the public to protect human health and the environment.
significant attention as a method to treat wastewater. The technology involves the oxidation of anode, which produces coagulants. This approach serves as a viable alternative to chemical coagulants for pollutant removal and provides an advantage for communities with better access to electricity than such chemicals. In this study, we conducted several electrocoagulation tests using aluminum electrodes to examine various operating parameters, including electric current, initial pollutant concentration, initial water pH, and electrode arrangement. We tested the removal of iron, fluoride and arsenic (V) in single contaminant experiments as well as binary mixtures and ternary mixtures. We determined the evolution of concentration throughout each trial along with total suspended solids and particle size distribution at their conclusion. We found that increasing electrical current improved the removal efficiency for all contaminants. For iron contamination specifically, higher pH values favored its elimination while fluoride and arsenic (V) exhibited opposite trends. Furthermore, during our experience with ternary mixture testing it appeared that the presence of other contaminants facilitated overall elimination results across all pollutants tested.

EMERGING
Emerging contaminants can be classified based on various criteria, including their source, chemical structure, persistence, and potential impact on human health and the environment:
Emerging contaminants in water refer to pollutants that have recently been identified or have become a concern due to their potential impact on human health and the environment. These contaminants can come from various sources, including industrial processes, agricultural runoff, pharmaceuticals, personal care products, and urban runoff. Examples of emerging contaminants include pharmaceuticals, personal care products, pesticides, hormones, perfluoroalkyl substances (PFAS), and microplastics. The presence of emerging contaminants in water bodies poses challenges for water treatment facilities and regulatory agencies. Many of these contaminants are not effectively removed by traditional water treatment methods, leading to potential exposure through drinking water and ecological harm to aquatic ecosystems. Efforts to address emerging contaminants typically involve a combination of monitoring, research, regulation, and technological innovation. Strategies for managing emerging contaminants
