Questions: Question 14 1 pts Biochemical Oxygen Demand Based upon these results, what would you recommend should be done at this point regarding Biochemical Oxygen Demand? No further action is necessary - the single elevated BOD reading is probably a fluke. The evidence of pollution is strong enough to warrant notification of local authorities about contamination in the White Oak Creek watershed (local city government, Environmental Protection Division of Georgia Department of Natural Resources). The evidence of pollution is strong enough to warrant notification of authorities about contamination upstream in the Chattahoochee River watershed. A plan for regular BOD sampling of the Chattahoochee River just upstream of the mouth of White Oak Creek should be implemented; BOD should also be tested at Site 3 under normal flow (from upstream) conditions.

The answer is the second one: The evidence of pollution is strong enough to warrant notification of local authorities about contamination in the White Oak Creek watershed (local city government, Environmental Protection Division of Georgia Department of Natural Resources).

Explanation for each option:

1. No further action is necessary - the single elevated BOD reading is probably a fluke.
   This option suggests that the elevated BOD reading is an anomaly and does not require further action. However, dismissing the reading without further investigation could overlook potential pollution issues.

2. The evidence of pollution is strong enough to warrant notification of local authorities about contamination in the White Oak Creek watershed (local city government, Environmental Protection Division of Georgia Department of Natural Resources).
   This option is appropriate if the elevated BOD reading is significant enough to suggest potential pollution. Notifying local authorities allows for further investigation and potential remediation efforts to address any contamination.

3. The evidence of pollution is strong enough to warrant notification of authorities about contamination upstream in the Chattahoochee River watershed.
   This option would be suitable if there were evidence suggesting that the source of pollution is upstream in the Chattahoochee River watershed. However, the question specifically mentions the White Oak Creek watershed, making this option less relevant unless additional data supports upstream contamination.

4. A plan for regular BOD sampling of the Chattahoochee River just upstream of the mouth of White Oak Creek should be implemented; BOD should also be tested at Site 3 under normal flow (from upstream) conditions.
   This option suggests a proactive approach to monitoring BOD levels, which is beneficial for ongoing assessment. However, it does not address immediate concerns about potential pollution, which is why notifying authorities is a more immediate action.

In summary, notifying local authorities about potential contamination in the White Oak Creek watershed is the most appropriate immediate action based on the evidence of pollution.
