State law requires the adoption of a maximum contaminant level (MCL) for PFAS contamination in drinking water by June 1, 2024. While discussion mitigation options has included degree risk reduction and cost treatment, indirect environmental effects are missing from conversation. Until other technologies developed, treatment Maine will likely rely on established, energy-intensive method adsorption (binding) to granular activated carbon.
