Which of the following is a common storm water pollutant?

Phosphorus is recognized as a common storm water pollutant due to its role in promoting algal blooms in water bodies. These blooms can lead to decreased oxygen levels, harming aquatic life and disrupting ecosystems. This nutrient can enter waterways through various sources, such as fertilizers, detergents, and animal waste, especially during rain events when storm water runoff occurs.

Nitrogen is also a significant storm water pollutant for similar reasons. Like phosphorus, nitrogen compounds contribute to nutrient loading in water bodies that can lead to algal blooms and subsequent oxygen depletion.

While oxygen is essential for aquatic organisms, it is not typically classified as a storm water pollutant. Instead, its levels are often influenced by other factors, such as organic matter decomposition and algal growth within the water.

Since both phosphorus and nitrogen are common storm water pollutants and can severely impact water quality, the correct understanding of this question lies in recognizing that phosphorus and nitrogen are included in the group of pollutants, while oxygen does not fit this classification. Therefore, stating that all the options are common pollutants is an inclusive approach to acknowledging the major contributors to storm water pollution.
