What substances are illegal to discharge into federally controlled or state waters?

The discharge of waste, oil, and trash into federally controlled or state waters is illegal due to environmental protection laws that aim to preserve the integrity of aquatic ecosystems. Waste, including sewage and untreated solid materials, poses significant health risks to both marine life and humans. Similarly, oil spills can have disastrous consequences for water quality and wildlife by creating toxic environments that can harm organisms at various levels of the food chain. Trash, particularly plastics and other non-biodegradable materials, contributes to pollution and can entangle or be ingested by marine animals, further disrupting the ecosystem.

Recognizing and adhering to these regulations is critical for maintaining clean water and protecting biodiversity, which are both essential for the health of our environment and for recreation and resource use. Hence, understanding the specific materials that are prohibited ensures that boaters contribute positively to the preservation of our waterways.
