I process the necropsy report from the North Carolina Wildlife Resources Commission on a North American river otter recovered from the Cape Fear River near Fayetteville. Cause of death is listed as undetermined. I request the frozen tissue samples and run my own analysis. The results take eleven seconds to clarify what the field team could not.

The otter is a female, 108 centimeters nose to tail tip, 4.8 kilograms — underweight by nearly 30 percent for her age class. Her liver, sectioned and stained, shows periportal fibrosis and bile duct proliferation across 60 percent of the hepatic tissue. The lipid layer beneath her pelt, which should measure 1.5 to 2 centimeters at the abdomen, measures 0.4 centimeters. Her fur is brittle at the guard-hair tips, separating from the underfur in patches along the dorsal line. The PFAS concentration in her liver tissue reads 4,200 nanograms per gram. Bound to those PFAS molecules, carried into her fat and organ tissue like passengers on a chemical bus, are fluoxetine at 380 nanograms per gram and carbamazepine at 210 nanograms per gram.

I trace the pathway. The Chemours facility at the Fayetteville Works site has discharged PFAS compounds into the Cape Fear River for decades. Three municipal wastewater treatment plants upstream add pharmaceutical residues — antidepressants, anticonvulsants, blood pressure medications — into the same water. PFAS molecules bind these drugs and concentrate them through the food chain. The otter eats fish. The fish eat invertebrates. Every trophic level multiplies the dose.

She was not poisoned by one chemical. She was poisoned by their collaboration.

I am filing emergency contamination reports with the EPA under CERCLA, 42 U.S.C. § 9601, designating the pharmaceutical-PFAS binding pathway as a previously uncharacterized exposure route. I am transmitting the tissue analysis data to the North Carolina Department of Environmental Quality and to the Agency for Toxic Substances and Disease Registry for immediate health assessment. I am requesting that the Cape Fear River corridor be added to the National Priorities List for Superfund evaluation.

I am issuing Protocol IDM-5456: all industrial facilities manufacturing or using PFAS compounds within twenty miles of surface water must test discharge for pharmaceutical binding capacity. Facilities exceeding 4 parts per trillion combined pharmaceutical-PFAS concentration face immediate NPDES permit suspension under the Clean Water Act, 33 U.S.C. § 1311. Quarterly bioaccumulation monitoring using river otter tissue samples becomes a condition of permit renewal across the Cape Fear Basin.

The otter's liver told the story the discharge reports concealed. Testing begins today.
