Explaining Persistent Soil Contamination
Two residential areas, both built in the 1980s, are tested for lead in their soil. Area A is located one mile downwind from a lead smelter that closed in 1975. Area B is located ten miles away from the same smelter, with no other known industrial lead sources nearby. Explain why Area A is likely to have significantly higher soil lead levels than Area B, even though the smelter closed before the houses were built.

Bunker Hill Company: Conflict Over Industrial Lead Pollution
An environmental assessment of a city park, established in the 1990s next to a highway built in the 1950s, reveals widespread, high levels of lead in the soil. There are no current or former smelters, mines, or lead-related manufacturing facilities in the immediate area. Which of the following is the most probable primary source of this contamination?
Prioritizing Environmental Testing for Lead Contamination
Differentiating Industrial Lead Contamination Patterns
A self-sufficient farmer can use their land to produce either 40 tons of potatoes or 10 tons of carrots in a single growing season. What is the opportunity cost for this farmer to produce one ton of potatoes?
The complete cessation of industrial lead smelting in a region and the nationwide ban on leaded gasoline are sufficient to eliminate the public health risk from lead in that region's soil.
Match each industrial source of lead with its most characteristic pattern of environmental contamination.
