You are an environmental scientist analysing water quality parameters from two different sources, Source A and Source B. These sources provide water to nearby ecosystems. Consider the following data table showing water quality parameters from two different sources. Based on this data, which of the statements is most likely true?

1. Higher nutrient levels in Source A suggest an increased likelihood of eutrophication.
2. Source B has higher Dissolved Oxygen and Total Dissolved Solids (TDS) than Source A, implying better water quality for the nearby ecosystems.
3. Lower Dissolve Oxygen levels in Source A indicate the potential for oxygen depletion due to increased organic matter decomposition.
D. Hypoxic and alkaline conditions in Source B can lead to the formation of algal blooms.

Parameter Source A Source B
pH 6.8 8.2
Dissolved Oxygen 2.5 mg/L 5.0 mg/L
Nitrate Levels 2.0 mg/L 0.5 mg/L
