Surface water and groundwater typically have a pH range of?

The pH range of surface water and groundwater is generally between 6.8 and 8.5, which reflects the natural conditions found in many aquatic environments. This range is essential for maintaining the health of aquatic ecosystems, as most aquatic organisms thrive within this pH spectrum. Water with a pH lower than 6.8 can indicate increased acidity, potentially harmful to fish and other aquatic life, while a pH exceeding 8.5 could indicate alkalinity, which may also pose challenges for biodiversity.

Understanding this range is crucial for water quality assessment and management. It helps in determining the overall health of water bodies and ensuring that they support the necessary ecological functions. The typical values suggest that natural processes, such as mineral dissolution and biological activity, are in balance, contributing positively to the water chemistry.
