what makes the the water of the aquatic system more basic? maybe the pollution?
Maybe. What aquatic system are you talking about?

for further discussion of what can make aquatic systems acidic or basic.
To determine what factors can make the water in an aquatic system more basic, it would be helpful to understand the specific aquatic system you are referring to. Different factors can contribute to changes in water pH, and subsequent acidity or basicity can vary depending on the environment.
One common factor that can affect the acidity or basicity of water is pollution. Industrial waste, agricultural runoff, or sewage discharge can introduce various chemicals into the water, potentially altering its pH level. For example, certain pollutants may increase the concentration of carbonate ions in the water, leading to higher alkalinity and a more basic pH.
However, it is essential to note that pollution alone may not be the only factor influencing the water's basicity. Natural processes, such as the weathering of rocks and the presence of alkaline minerals, can also contribute to the basicity of water in aquatic systems.
To get more specific information about the aquatic system you are interested in, I recommend referring to relevant scientific research, government reports, or environmental monitoring data. Local environmental agencies or organizations like the Texas Commission on Environmental Quality (TCEQ) might have valuable resources that discuss factors contributing to the water's acidity or basicity in a particular area.
For example, you can visit the TCEQ website and explore their Compliance Monitoring Database, which provides daily information about various parameters, including pH (acidity/basicity) in different aquatic systems within Texas. This resource can offer insights into the factors influencing water basicity and help you understand the issue on a larger scale.
