Hudson River PCBs: GE discharges and cleanup

The allegation

GE discharged PCBs into the upper Hudson from 1947 to 1977. The issue is industrial release management and cleanup, not every downstream illness.

Timeline

EPA listed the river as Superfund in 1984, selected a remedy in 2002, and dredged reaches in 2009–2015.

What the record establishes

EPA records identify sources, contamination, remedy, and monitoring. NY fish advisories reflect exposure precautions, not individual diagnosis.

Counterevidence and alternative explanations

Other sources and sediment transport contribute. Concentrations vary by place, depth, species, and time; residual detection alone does not prove cleanup failure.

Uncertainty and limits

Ecological exposure is clearer than individual disease attribution. Sediment movement complicates trend comparisons.

Calibrated skeptical verdict

GE releases and contamination are established. Specific health claims or fabricated-sampling allegations need separate proof.

What could change the assessment

Independent sediment cores, fish data, transport models, and remedy reviews could change residual-risk conclusions.
