Water chemistry is the study of the chemical composition and properties of water. It involves understanding how various substances, such as minerals and gases, dissolve in water and how these interactions affect water quality. Key factors include pH, temperature, and the presence of contaminants, which can influence aquatic life and ecosystems. In addition to natural processes, human activities can significantly impact water chemistry. For example, agriculture can introduce fertilizers and pesticides into water bodies, while industrial discharges may release harmful chemicals. Monitoring and managing these factors is essential for maintaining clean and safe water for both humans and wildlife.
