What is the key concern when managing runoff during a decontamination operation?

The key concern when managing runoff during a decontamination operation is preventing contamination from spreading. This is critical because during any decontamination process, hazardous materials or contaminants can be washed off surfaces or individuals and enter the environment, which could pose risks to public health and safety.

Effective runoff management involves controlling the movement and containment of contaminated water to ensure that it does not infiltrate soil, waterways, or other areas where it could affect unintended targets, such as the general public or wildlife. By focusing on preventing the spread of contamination, response teams can minimize the overall impact of the hazardous situation, protect responders and the community, and facilitate a safer clean-up process.

While visibility, maintaining water supply, and limiting first responder exposure are also important considerations during a decontamination operation, they are secondary to the paramount goal of controlling and containing contaminants to prevent further spread.
