What is involved in the full decontamination of a watercraft?

The process of full decontamination of a watercraft requires a systematic sterilization of all parts that have come into contact with high-risk water, which is critical to prevent the spread of aquatic invasive species (AIS). This comprehensive approach includes not just cleaning the visible surfaces, but also addressing hidden areas like bilges, live wells, and any internal compartments that could harbor invasive organisms.

Effectively achieving thorough decontamination ensures that all potential life forms, including eggs and larvae, are eliminated, safeguarding water ecosystems from the introduction of harmful species. The method typically involves using high-pressure hot water, along with approved cleaning agents, to thoroughly treat the craft, making it safe for transport and usage in different water bodies.

Basic cleaning of surfaces or only a power wash do not address the potential complexities of contamination, and simply spraying water at high temperature without ensuring coverage of all critical areas would not guarantee the elimination of all invasive species. Thus, the systematic approach detailed in the correct answer is the only method that meets the rigorous standards required for full decontamination.
