The problem that exists in the Susquehanna River is far more ominous than nutrient pollution. Smallmouth bass are intersexed, they are dying from opportunistic infections that suggest immune incompetence and now they are displaying abnormal collections of melanin (black pigment) which could represent cellular dysplasia (melanoma/cancer)or hormonal dysregulation of melanin deposition. These three problems suggest chemicals in the water that could present significant public health risks for people eating the fish and using the water for drinking and recreation. While nutrient pollution can indeed damage the environment, chemical endocrine disruptor pollution has greater potential consequences for public health.
The problems need immediate and aggressive evaluation and this impaired watershed needs to be cleaned up now.

You raise some excellent points, Dr. Yingling.

Endocrine disrupting chemicals are indeed a suspect in the intersex problems among the smallmouth bass in the Susquehanna and other rivers, although exactly which chemicals and what their sources are remain unclear.

The kinds of pollution limits being contemplated as part of a possible impairment listing and Clean Water Act Total Maximum Daily Load for the river typically do not include endocrine discruptors -- such as drugs or herbicides or soaps -- so perhaps an updating of the standards are needed.
