Which method can be used to reduce the amount of hazardous material flowing into the environment?

Using diking is an effective method to reduce the amount of hazardous material flowing into the environment. Diking involves creating barriers, typically made of earth or other materials, around a hazardous spill to contain it. This physical confinement stops the hazardous material from spreading into surrounding areas, such as water sources, soil, or populated regions.

When diking is properly implemented, it can significantly minimize the impact of spills and leaks, allowing for more controlled cleanup and remediation efforts. This practice is essential in preventing further environmental harm and protecting human health, especially in scenarios where hazardous materials are involved.

In contrast, while dilution may seem like a quick fix, it can actually lead to wider contamination if the hazardous substance spreads into larger volumes of water or soil. Adsorption and dispersion might manage or alter the material but do not provide the immediate containment offered by diking.
