Diking is defined as

Diking is defined as

• A. Contamination technique that is used when liquid is flowing in a natural channel or depression and its progress can be stopped by blocking the channel.
• B. Adding water to a solution to decrease the concentration
• C. The placement of materials to form a barrier that will keep a hazardous material in liquid form from entering an area, or that will hold the material in an area.
• D. Intended to redirect a liquids flow from an endangered area to an area where it will have less impact (usually storm drains)

Answer: (C)

Diking means building a barrier around or enclosing a spill to keep the hazardous liquid from spreading and to hold it in the defined area. This is typically done with earth, berms, sandbags, or other temporary barriers to protect nearby areas, drains, and sensitive environments and to make cleanup easier. The goal is containment, not dilution or diversion. The other ideas describe blocking a channel, diluting the material, or directing flow away into drains—these address flow paths rather than creating a barrier to keep the liquid in place, so they aren’t diking.
