Final answer:
Without specific tests and data, it is not possible to definitively determine which water source is the 'cleanest' between Lee Falls Lake, Bartley Creek at McCoy Dam, and Bates Creek. Cleanliness could depend on impurities or bacterial content. Correct answer may be 'None of these' due to lack of data.
Step-by-step explanation:
The 'cleanliness' of a water source largely depends on the criteria we choose to use. This could be based on the amount of impurities in the water, such as sediment or pollutants, or it could be based on the bacterial content of the water. Without specific tests and data, it is not possible to definitively determine which water source is the 'cleanest' between Lee Falls Lake, Bartley Creek at McCoy Dam, and Bates Creek. Therefore, the correct answer may indeed be 'None of these' because we do not have enough data to make an accurate comparison.
