Passage Summary: Because the local budget won't allow for new inspectors, large dairies are going to fail their waste management standards. The author concludes this will lead to polluted drinking water for the district.

Conclusion: The drinking water in the district will likely become contaminated.

Reasoning: The current budget prevents hiring more dairy inspectors, which means most large dairies in the valley will fail to meet federal waste disposal standards.

Analysis: The argument makes a significant leap from 'dairies failing waste standards' to 'the district's drinking water becoming polluted.' While the stimulus mentions that waste can seep into groundwater, it doesn't guarantee that the failure of these specific dairies will inevitably result in district-wide pollution. To make this argument logically sound, we need a bridge that guarantees this outcome. Look for an answer choice that confirms that if these large dairies fail to meet those specific federal standards, the district's water supply will indeed be compromised.
