Why is groundwater salty?

Why is groundwater salty?

Groundwater salinity is generally of 3 types: (i) natural/primary salinity caused as a result of dissolution of minerals (e.g. halite, anhydrite, carbonates, gypsum, fluoride-salts, and sulphate-salts) from bedrocks or accumulation of salts from rainfall built up over time, hence the residence time of these may be …

Is groundwater salty like the ocean?

Very deep groundwater is normally very saline, much of it is connate water, sea water deposited with the sediments forming the sedimentary rock containing it. Localized salt intrusion may come from salt domes contributing chloride to the surrounding groundwater.

What is saltwater intrusion and how does it affect the groundwater?

Saltwater intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences. Saltwater intrusion can naturally occur in coastal aquifers, owing to the hydraulic connection between groundwater and seawater.

Why does groundwater become easily contaminated?

Groundwater is also one of our most important sources of water for irrigation. Unfortunately, groundwater is susceptible to pollutants. Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use.

• Septic Waste.
• Landfills.
• Hazardous Waste Sites.
• Storage Tanks.
• Atmospheric Pollutants.
• Underground Pipes.
• Road Salts.
