Which of the following statements is true regarding surface water?

Surface water is typically characterized by the presence of algae and turbidity. Algae are a common occurrence in surface water bodies, such as lakes, rivers, and ponds, due to the availability of nutrients and sunlight. This biological productivity can lead to a noticeable green or cloudy appearance, which is referred to as turbidity. Turbidity is often a result of various particles suspended in the water, including silt, microorganisms, and organic matter.

Given these characteristics, the statement that surface water contains algae and turbidity accurately reflects the common conditions observed in surface water bodies. This is important for water quality management and treatment processes, as high levels of algae can indicate nutrient pollution and may lead to further complications, such as the growth of harmful algal blooms.

In contrast, surface water may not consistently be low in bacteria or high in minerals, as these factors can vary widely depending on the environment and surrounding land use. Additionally, while surface water can have dissolved solids, it doesn't inherently possess high levels compared to other water sources, such as groundwater. Understanding these distinctions is crucial for those pursuing knowledge in water treatment and management, particularly for a Texas Class D Water License.
