What might happen if there is excessive water removal from the central valley, aquifer in California
If there is excessive water removal from the central valley aquifer in California, several negative consequences could occur:
1. Land subsidence: Excessive water removal can cause the ground surface to sink, leading to land subsidence. This can damage infrastructure such as buildings, roads, and pipelines.
2. Saltwater intrusion: Excessive water removal can lead to the intrusion of saltwater into the aquifer, making the water unusable for irrigation and drinking purposes.
3. Decreased groundwater availability: Excessive water removal can deplete the aquifer, reducing the availability of groundwater for agriculture and other uses.
4. Environmental damage: Excessive water removal can harm natural ecosystems that depend on groundwater, leading to the loss of habitats and species.
5. Increased pumping costs: As the water table drops due to excessive water removal, farmers and other users may have to pump water from greater depths, increasing the cost of water extraction.
