The correct answer indicates that improper management of wash water does not contribute to the prevention of point-source pollution. Point-source pollution refers to contaminants that enter a water body from a single, identifiable source. Proper management of wash water is crucial in preventing point-source pollution; if wash water is improperly managed, it may lead to the direct discharge of pollutants into water bodies, thus contributing to pollution.

In contrast, the other options provided represent effective measures for preventing point-source pollution. For instance, properly disposing of empty pesticide containers helps ensure that hazardous waste does not leach into the soil or water systems. Cleaning up spills at pesticide storage sites reduces the chance of chemicals entering water sources, and preventing leaks when loading pesticides directly minimizes the risk of polluting the surrounding environment. Each of these actions is aimed at managing the sources and pathways through which pollutants can enter aquatic systems.
