Maine has a sewage sludge problem. A byproduct of wastewater treatment, sludge has to be disposed of somehow. However, our sole disposal option is quickly becoming untenable and we have no backup plan in place. Until recently, most of Maine’s nutrient-rich sludge was destined for land application. Following the discovery that this practice was contaminating soil and water with PFAS, Maine banned land application in 2022. Therefore, landfilling is Maine’s single sludge-disposal option. This is deeply problematic. Long-haul transportation is expensive. Rotting sludge emits the potent greenhouse gas methane, accelerating climate change. PFAS-laden, wet sludge may leach contaminants into local soil, groundwater and water bodies. And we are fast running out of in-state landfill space. We need a sustainable plan of action. ~ David Conwell, Citizens’ Climate Lobby
