Which process involves removing high-risk water and replacing it with hot water?

The process of removing high-risk water and replacing it with hot water is known as standing water decontamination. This technique is critical in managing aquatic invasive species (AIS) because it focuses on eliminating organisms that may be residing in water that has been stagnant or is no longer flowing. Hot water serves as an effective method for killing many types of invasive species, making it an essential part of preventive measures to protect local ecosystems.

In situations where water has been standing, it can accumulate various organisms that may pose a threat to native species or ecosystems once reintroduced to different water bodies. By using hot water, this decontamination method effectively sanitizes the standing water, ensuring that any remaining invasive species or pathogens are eradicated before the water is returned to an environment where it could cause harm. Thus, understanding and implementing standing water decontamination is vital for anyone involved in watercraft maintenance or aquatic environment management.
