## Water Extraction and Its Impacts
Water extraction is the process of removing water from an aquifer, lake, river, or other ground or surface water source. It is essential for various human activities, including municipal water supply, irrigation, and industrial processes. However, water extraction can also have significant impacts on the environment.
## Consequences of Water Extraction
Excessive water extraction can lead to:
– **Lowered Water Tables:** Water extraction can lower water tables, impacting groundwater-dependent ecosystems, such as wetlands and springs.
– **Reduced Streamflow:** Water diversion for extraction can reduce streamflow, affecting aquatic habitats and downstream water users.
– **Land Subsidence:** In areas with soft or compressible soil, extensive groundwater extraction can lead to land subsidence, causing infrastructure damage and property loss.
– **Saltwater Intrusion:** In coastal areas, over-extraction of groundwater can draw in saltwater, contaminating freshwater aquifers.
– **Reduced Water Quality:** Water extraction can alter the chemical composition of water sources, potentially increasing the risk of contamination and affecting human health.
